				<content:encoded><![CDATA[<p><strong>This year&#8217;s Mont 24hr mountain bike race was totally different from the generally miserable time I had the previous year. Not having to crawl out of a sleeping bag to face 1 degree centigrade temperatures and the wind at 4am certainly helped, but the biggest improvement was made</strong> <strong>by the MyTinySun Sport 2700x trail light that allowed me </strong><strong>to really see where I was going. This update on these lights has been a while coming (the first part,</strong> <strong><a title="MyTinySun Sport 2700X Trail Light in Review" href="http://www.bicycles.net.au/2012/12/tiny-sun-sport-2700x-trail-light-review/">MyTinySun high powered light review</a>, was done in December last year), but giving these lights a proper workout was important, for journalistic integrity and so on, and absolutely not to give me a performance advantage. Honestly.</strong></p>
<p><strong><br />
Previously, at The Mont 24&#8230;</strong><br />
In 2012, my then 3-year-old Ay Ups seemed perfectly adequate for the race ahead. They were great for night commuting and the occasional fire trail social night ride I’d been doing with mates. Indeed, the previous year at my first ever Mont, they really did seem fine. It was an unpleasant surprise to find then, come race day, when scooting through the twisty Kowen Forest singletrack, their weaknesses jumping out like a hungry drop bear.</p>
<p>Mounted on the handlebar, the bright Ay-Ups’ intense hotspot and rapid drop-off to the sides created a tunnel vision effect. This forces the rider to scan with the helmet light and fill in the gaps between the hotspots and front wheel from memory. I found this very tiring and difficult to maintain at race speed on twisty rerrain.</p>
<p>Sections like Kowalski&#8217;s Sideshow and Rolling Thunder became particularly difficult at night, with the bar light pointing out into the inky black off the side of the hill around the fast banked hairpins. This left no choice but to use the helmet light on the foreground instead of looking around the corner.</p>
<p>The Ay-Ups just weren&#8217;t doing it. It was an unpleasant slog. I wasn&#8217;t sure if I was up for putting myself through that again.</p>
<p><strong><br />
Jump forward 12 months: a new toy arrives</strong><br />
When the MyTinySun light arrived late last year, I felt like 007 getting his new toys from Q before a dangerous mission. My manic work schedule (yes, I have a real job) meant midweek practice trail rides with the new kit didn&#8217;t happen. Nevertheless, I was quietly confident I had a secret weapon in my hands. For the Mont 24 MTB race in Canberra, the Ay-Ups were relegated to helmet light duties where the hotspot would be handy.</p>

<p><img src="http://www.bicycles.net.au/wp-content/uploads/2013/04/handlebar_mounted_mountain_bike_night_light.jpg" alt="Handlebar Mountain Mountain Bike Night Light" width="500" height="333" /></p>
<p><strong><br />
Turning night into day</strong><br />
Come the first night lap, I knew early on I was going well when I noticed how far forward I could plan lines and how relaxed I felt. The full, even beam from the MyTinySun meant peripheral vision could handle the load as in daytime and I no longer had to ride by memory. This set in motion a virtuous cycle. Not being constantly surprised, and being able to stay off the brakes much more when setting up for corners, helps maintain momentum instead of wasting energy. The increased speed and lower effort means flowing lightly over obstacles, if not popping the bike over them altogether, instead of having to grind and bounce my way through every rock garden and mass of tree roots.</p>
<p>Sections like Kowalski&#8217;s Sideshow that were tricky to ride fast, still required full concentration but were a blast to ride. The Sport 2700x allowed you to see clearly the exit line you were aiming for while still giving you a great view of the foreground and everything to the side and in between. This freed up the helmet light to do its job of searching ahead for what was coming next.</p>
<p>The result was a first night lap that was my fastest of the event: 1 hour 8 minutes-odd, according to the Garmin, on a course two kilometres longer &#8211; a massive improvement of 26 minutes over the last year, in the same conditions. This compared well with the elite&#8217;s night laps at around the 53 minute mark. Not bad for an old fart.</p>
<p><img src="http://www.bicycles.net.au/wp-content/uploads/2013/04/mont24_night_mtb_lights_mytinysun.jpg" alt="Mont24 Night MTB Lights from MyTinySun" width="500" height="333" /></p>
<p>On the second night lap I found myself struggling a little, until I figured out I’d been running the 2700x in half-power mode for the first half. Out of habit I’d dimmed the light to conserve battery on the first long slow climb. In the rush to hit the mode button before arriving at the next fast technical section I had somehow missed clicking it properly.</p>
<p>Back on full beam, confidence returned. Shape-making on the bike and line selection improved and speed through the winding singletrack just seemed to lift of its own accord without extra effort.</p>
<p>A check on the Garmin as I crossed transition showed 1 hour 14 minutes and some seconds. Not at all bad, considering the first half. My last lap, in mid-morning Sunday sunshine, would come in at 1 hour 12 and some cramps. Consistent!</p>
<p><img src="http://www.bicycles.net.au/wp-content/uploads/2012/12/mytinysun_sport_2700x_beam.jpg" alt="MyTinySun sport 2700x Beam" width="500" height="333" /><br />

<p><strong><br />
Excellent battery life</strong><br />
Why I felt the need to dim the light on that climb I am not quite sure. My lap times were never going to threaten the 2 hour 47 minute run time on full beam specified on the light’s spec sheet. The battery status indicator only just tripped over to indicating 75%  capacity ten minutes or so before hitting the transition area on the first lap, so the spec sheet run time seems quite realistic.</p>
<p>The light head does get more than a little warm on full power when standing still, but even spinning up steep gradients at 6-7km/hr seems to provide enough airflow to keep it no more than warm to the touch.</p>
<p><img src="http://www.bicycles.net.au/wp-content/uploads/2012/12/mytinysun_package.jpg" alt="MyTinySun package" width="500" height="333" /></p>
<p><strong><br />
Mounting hardware that works</strong><br />
Despite spending several weeks fixed 24&#215;7 on my commuter bike, the O-ring light head mount was just as secure on the Easton carbon bars of my race bike on the rough stuff. I shifted the aim up and down slightly a couple of times during the lap to suit the terrain, but this was a plus not a minus.</p>
<p>The Velcro fasteners kept the battery securely nestled up front between down and top tubes, and the cable connectors behaved perfectly.</p>
<p><img src="http://www.bicycles.net.au/wp-content/uploads/2012/12/my_tiny_sun_connectors.jpg" alt="My Tiny Sun Connectors" width="500" height="333" /></p>
<p>The connectors are difficult to pull apart, which is confidence inspiring as the last thing you want on a fast rough descent is for your light to suddenly wig out from a dodgy connector. Gripping each connector end firmly and flexing from side to side loosens the connection easily without stressing the wires. I managed to deduce this by studying the plug&#8217;s design, and this omission is probably the only complaint I would have about the instruction sheet.</p>
<p><strong><br />
With great power&#8230;</strong><br />
One consequence of having so much light at one&#8217;s fingertips is that it imposes a responsibility to be careful with its use. The instructions carry a warning against looking directly into the beam when handling the unit due to the risk of permanent damage to your vision, and they&#8217;re not kidding.</p>
<p>On one occasion commuting home, after hitting full beam on a fast descent that is periodically prone to having oil sprayed across the kerbside lane by government buses, I came to a sudden stop behind a small hatchback at the red traffic light at the bottom of the hill. The full 2700 lumens fired straight in the back window. An almost instant  &#8221;What the hell is that?!&#8221; exploded from the driver (I&#8217;ve cleaned up the language) followed by a sheepish mumbled apology from me and my hand quickly covering the light while I bumped the intensity down.</p>
<p><strong>Light Modes</strong><br />
As noted in the race report above, it is still possible to get confused about which light mode you&#8217;re in. In a race situation stopping to check is not something you prefer to do, and taking one&#8217;s hands off the bar to dab the button carries some obvious risks! This is no different to any other competitor&#8217;s light and so can&#8217;t be highlighted as a disadvantage, rather it&#8217;s something I would like to see addressed in any MTB light set up.</p>
<p>My other suggestion about the modes involves the flashing mode, or rather the lack of a regular one. The only flashing mode available gives you an SOS morse code signal that cannot be disengaged without unplugging the light. It is obvious that MyTinySun are not aiming this light at the city commuting market, rather it is intended to attract the serious mountain biker or back-country rider. Having a light that can be more useful on commutes, however, would help to justify its price.</p>
<p><img src="http://www.bicycles.net.au/wp-content/uploads/2012/12/mytinysun_sport_2700x_mountain_bike.jpg" alt="MyTinySun sport 2700x Mountain Bike" width="500" height="333" /></p>
<p><strong><br />
Conclusion</strong><br />
My experience at the Mont speaks for itself. For their intended use as off-road trail lights, the Sport 2700x really hits the mark. The remarkable light output with a wide and even beam spread changed my riding from grinding and picking my way carefully around barely-seen obstacles, to flowing my way to bettering my night time lap speeds. Even with a whopping 2700 lumens, these still work best in combination with helmet mountain light which can be a lower powered light with a hotspot.</p>
<p>I&#8217;m really grateful to the importers for the opportunity to test this light, as I had almost given up on night mountain bike riding. It transformed a challenging, unpleasant and tense experience into the brilliant fun it always should have been, and has restored my appetite for night racing. I can&#8217;t wait for the next event!</p>
<p>MyTinySun also have handlebar remote versions: Pro 2800x (also with 3 Cree LEDs) and a dual lamp (6 Cree LEDs) called the PRO 3600X. Yes, that&#8217;s right, 3600 lumens of light. That will burn holes into the landscape!</p>
<p><strong>Great:</strong><br />
• Wide, even beam spread.<br />
• Awesome total light output and punch<br />
• Outstanding run time<br />
• Easy to use<br />
• No &#8220;off&#8221; phase when switching between intensity modes.</p>
<p><strong>Not so great:</strong><br />
• No flash mode for commuter use<br />
• Easy to dazzle other road users if you&#8217;re careless</p>
<p>MyTinySun lights are available directly from the Australian <a title="MyTinySun Sport 2700x " href="http://mytinysun.com.au/products/bicycle-lights/sport-2700x-led-bicycle-light.html" target="_blank">MyTinySun website</a>, the Sport 2700x as review retails for $629 the 5.8Ah battery pack.</p>

				<content:encoded><![CDATA[<p><strong>&#8220;Arms race&#8221; is a phrase used many times in the BNA forums to describe the advances in bike lights over the last few years, and it&#8217;s not too far from the truth. The light output that we could only dream of a few years ago is now readily available and it&#8217;s getting cheaper. Light efficiency has improved to the point where we can now rival car headlight outputs, if needed, for several hours from batteries not much bigger and heavier than a 250ml fruit juice pack.</strong></p>
<p>The Ferei BL200 is one of the most recent entrants into this race and, at a recommended retail price of $229, is outstanding value for money. At a claimed 1600 lumens, it generates enough output to paralyse possums and fry feral rabbits around my local trails. While there is a defined hotspot, there is enough beam spread to be comfortable on all but the tightest of twisty trails.</p>
<p>The light head comprises two Cree XM-L T6 LEDs in a robust weather-resistant aluminium housing with one of the most nicely engineered tool-free handlebar mounts I&#8217;ve seen. Moulded rubber inserts are included in three different thicknesses to provide a snug fit across a wide variety of bars. The thinnest was a perfect fit for my Easton 31.8 mm mountain bike riser bars. So far there has been no slippage at all, despite using them on some sketchy, rough trails.</p>
<p><img src="http://www.bicycles.net.au/wp-content/uploads/2012/11/ferei_bl200_profile.jpg" alt="Ferei BL200 Bike Lights" width="500" height="336" /></p>
<p><img src="http://www.bicycles.net.au/wp-content/uploads/2012/11/ferei_bl200_quick_release.jpg" alt="Ferei BL200 Quick Release" width="500" height="336" /></p>
<p><img src="http://www.bicycles.net.au/wp-content/uploads/2012/11/ferei_bl200_mountain_bike_mounted.jpg" alt="Ferei BL200 Mountain Bike Mounted" width="500" height="336" /></p>
<p><img src="http://www.bicycles.net.au/wp-content/uploads/2012/11/ferei_bl200_kit.jpg" alt="Ferei BL200 Kit" width="500" height="336" /></p>
<p>The included sealed battery is a compact 7.2V 4400mAh Li-Ion unit, and is supplied in a colour to match the anodised head unit. It comes with a rubber pad moulded in to the body to prevent frame scuffing, though, for riding in the dirt, I recommend applying some clear tape or Frameskin material to your frame first.</p>
<p><img src="http://www.bicycles.net.au/wp-content/uploads/2012/11/ferei_bl200_battery_mounted.jpg" alt="Ferei BL200 Battery Mounted" width="500" height="336" /></p>

<p>Besides the nominal 1600 lumen high beam, it has a tunable low-beam mode and a choice of three flashing modes. High beam is the default, a second click of the button drops the beam to low, and a third turns it off. Flash mode is engaged by starting with the unit turned off and holding down the power switch for a couple of seconds. A small LED flashes to indicate battery charge level and the high beam run time easily surpasses the claimed hour-and-thirty minutes.</p>
<p>As a commuter, it was reassuring to have flashing lights this powerful. I was concerned about not having the ability to aim the BL200&#8242;s at inattentive drivers, like you can do with helmet mounted lights, but so far my experience has, overwhelmingly, been that drivers not only notice you, but are more courteous than if you were driving a car.</p>
<p><img src="http://www.bicycles.net.au/wp-content/uploads/2012/11/ferei_bl200_high_beam.jpg" alt="Ferei BL200 High Beam" width="500" height="336" /></p>
<p><img src="http://www.bicycles.net.au/wp-content/uploads/2012/11/bl200_light_beam.jpg" alt="Ferei BL200 Bike Light Beam" width="500" height="336" /></p>
<p>In flash mode, my previous experience with a high-end Cateye &#8220;look at me&#8221; type flasher, was that drivers would either not register your presence or, more usually, seem to take the view that &#8220;it&#8217;s only a bike&#8221; and pull out in front of you anyway. With this amount of photonic grunt, drivers both notice you earlier <em>and</em> treat you with respect. The BL200s give you real &#8220;presence&#8221; on the road, even if you use them during the day.</p>
<p>One potential consequence of so much light output is blinding other cyclists; I&#8217;ve had to be careful to avoid using high beam when crossing the Sydney Harbour cycleway after dark, despite having the BL200s head unit pointed a couple of degrees below horizontal. Flash mode seems to be acceptable to oncoming cyclists with no complaints against them vocalised to date, unlike my usual Ay-Up V4s which used to regularly get grumpy comments from the commuter brigade.</p>
<p><img title="Ferei BL200 Light Beam Road" src="http://www.bicycles.net.au/wp-content/uploads/2012/11/ferei_bl200_beam_road.jpg" alt="Ferei BL200 Light Beam Road" width="500" height="336" /></p>
<p><img src="http://www.bicycles.net.au/wp-content/uploads/2012/11/ferei_bl200_view_above.jpg" alt="Ferei BL200 Switch" width="500" height="336" /></p>
<p>The BL200s functionality would be improved for trail use by separating the on/off switch from the mode switch. While most experienced mountain bike riders would be likely to have a separate helmet light when out on the trails, it would be better not to have to pass through &#8220;off&#8221; before getting high beam again. I also found myself getting confused on a couple of occasions, inadvertently entering low beam adjustment mode when I really wanted flash mode. With time and practice this would be less of an issue.</p>
<p>This brings me to the subject of beam spread. One of the issues I experienced on the fast, tight, descending switchbacks at the Mont 24 this year was the serious tunnel vision effect from my Ay-Ups. Due to the narrow beam, the bar light would point off into space instead of down the trail, and I&#8217;d have to use the helmet unit to fill in the gap in front of my front tyre, instead of looking further around the corner. This meant slowly &#8220;tippy-toeing&#8221; around the corners with the Ay-Ups, riding the brakes hard instead of flowing, all contributing to mental fatigue and really not enjoying the sections of track that had me hooting and whooping at race speed during the day.</p>
<p><img src="http://www.bicycles.net.au/wp-content/uploads/2012/11/ferei_bl200_mountain_bike_beam.jpg" alt="Ferei BL200 Mountain Bike Beam" width="500" height="336" /></p>
<p><img title="Ferei BL200 Mountain Bike Light Beam" src="http://www.bicycles.net.au/wp-content/uploads/2012/11/ferei_bl200_beam_mountain_bike.jpg" alt="Ferei BL200 Mountain Bike Light Beam" width="500" height="336" /></p>
<p>For mountain biking, the BL200s are a vast improvement over the Ay-Ups, and if the beam had a little less hotspot and only a little bit more beam spread without the sharp cutoff at the edge, they would have gone from being very good to just about perfect. For road commuting, the Ferei BL200s are exceptional.</p>
<p>I&#8217;ll be shopping for new lights very soon and these are definitely on the short list. As a mountain biker, teaming these lights on the bar with a B5 680 lumen light on your helmet will give you a sub-$400 setup that&#8217;s competitive with products twice the price.</p>
<p><strong>Pros:</strong><br />
Beam throw is outstanding<br />
Solid, stable tool free mount<br />
Light and small setup<br />
&#8220;Dude, get off my road!&#8221; flash mode, even in the day<br />
Outstanding value for money for recreational mountain bikers and commuters</p>
<p><strong>Cons:</strong><br />
Would have preferred a wider beam spread for off-road race use</p>
<p>The Ferei BL200s are available in black, red, blue, and gold/yellow from <a title="Ferei BL200" href="http://www.ferei.com.au/bicycle-lights/ferei-bl200-1600-lumen-led-bicycle-light.html" target="_blank">Ferei Australia</a> for $229.</p>
