It's no secret that I use and like the stuff made by Planet Bike. Use the search function on this blog and you'll find me saying various nice things about various Planet Bike products. I was getting ready to write a review of the light I've been commuting with for the past month, the 2 Watt version of the Blaze, but when I checked Amazon a couple of other folks already said pretty much all the nice things I was going to say about this light. So click the link above and read the reviews there and then come back and I'll add a little bit.
OK, it's a nice light. It uses 2 AA cells and it works great with NiMH rechargeable batteries. It works fine for commuting but if I was going to ride all night on a brevet, I'd take some spare batteries just to be safe. I have good night vision and run it on the low setting most of the time and on low it'll run all night. The light uses the same mount as its 1-Watt and 1/2-Watt siblings as well as the Beamer 3 and Beamer 5 lights, something I find handy because I have several bikes and swap various Planet Bike lights between them.
The 2-Watt Blaze project fairly tight cone of light with a bit of spill and as to be expected, on the low setting on the 2-Watt Blaze seems to be just about as bright as the high setting of the 1-Watt Blaze. LEDs seem to run more efficiently at lower power so the 2-Watt on low makes better use of the batteries than running the 1-Watt on high. Plus, it is nice to have the higher beam available for quick, dark descents.
In cold, wet weather I've noticed some condensation inside the lens of the light, but it hasn't caused any problems.
Finally, I prefer the sleek, Darth Vader black of the 2-Watt Blaze to the i-Mac white of the 1-Watt model.
Keep 'em rolling,
