It uses the same bulb as the Turtle Light 1, which was horribly dim and narrow. For its day it was almost a revolution - the concept of a long throwing LED flashlight. But to me, the fixed-focus TL1 was too narrow to be of use up close, and too dim to be of use further away, and now is old news. Plus it was bulky and expensive for its output, if it were smaller it wouldn`t seem so bad. The only upside was the run-time which was measured in days or something mad like that.
The aluminum one, from what I have been able to gather, gives the same narrow beam but has an option to de-focus it and introduce some rings and donut-holes, spreading that weak light over a bigger area. I have never seen one in person, but just going by specs on paper, next to a MaxaBeam it`s nothing. Though it has a similar cold-white narrow beam, it is many orders of magnitude dimmer (~60cd vs ~6000000cd), and would need a whole lot of stage-smoke and complete darkness to get the beam to show up through the air. You will be dissapointed I`m sure.
There aren`t many other commercially made narrow-beam LED lights out there right now. PT Impact is one (there is also a smaller Impact 2 now), and the Inova X1 is another. Both use lenses to focus the beam, and the Inova is actually quite bright and useful in some aspects. No side-spill whatsoever though, which is one thing the LEDCorp lights have in abundence. Even ground down, most of the light from a Nichia 5mm LED goes out of the top away from the reflector, which is one explanation as to why the TL1 is so dim.
If you want the LEDCorp light, hunt down a Dorcy Cool Blue instead (at Walmart, etc) - it`s the exact same thing but a lot cheaper. A better option would be then to fit it with an EverLED Luxeon LED drop-in bulb, avaliable from CPF advertiser LED-Supply. You should probably be able to focus it to an decently narrow beam, and it will be significantly brighter and more useful too. Note that I have not tried this combination myself (I don`t have either of them, only information), but it should work.
