dont no but it works really good i put it on my sand car .it takes a hit well.

I am not familiar with the Cree light but I have used a Niterider Trail Rat. I find the Cygolite better for my commute. I ride streets that are not lit and find the Cygolite more than adequate. The steady plus pulse mode is an added advantage. It makes the bike more visible.

i have both light color looks same, i did have a cree fail after 6 months ,, none of my Philips have

Yes - as long as you have the right wavelength (color) blue LEDs then it will work. There's nothing magical here...Cree make some suitable blue LEDs and they are far brighter than those used in this unit so you won't need anything like as many (look for a wavelength around 470nm which seems to be the wavelength our eyes ganglion cells respond to). So you need maybe 4 high power LEDs, appropriate drivers and heat sinks, a mounting box, a power source and you're done!

You will have to look and see if you can find what the lumens are on the Sylvania lights. The Cree put out 2000 lumens. I am sure that the LED will last much longer than the Sylvania.

You are correct that many LED lights are sadly lacking lumen specs. I don't nomally buy ones without lumen specs unless I don't have much choice for my application and then I cross my fingers or check a lot of reviews. High powered CREE LED's are more expensive than piling in a bunch of lower output cheap ones. Pick your price point and good luck finding lumen ratings.

Halogen is hotter and uses more power ( watts ) . The LED will use less and last longer , generally more of a direct light from LED and whiter . I think its a win win for you .

Sorry, I don't know. In researching microscopes recently I first learned that LED's are not necessarily standardized and may be proprietary. Thus, it would probably be wise (for both of us) to request the specification for the LED's used in the fixture. In fact, I'm going examine mine to see if the lights are even replaceable. It might be one of those disposable objects.

I'm pretty sure that cree refers to the technology used to produce the light, referring to the led chip that is used instead of a standard bulb. Regardless, this flashlight is very nice and I'm happy with my purchase of four of these. They are good quality, heavy and sturdy, and worth the price.

The defender is basically the single output version of the same light. So it is a matter of your preference in terms of what you need and prefer. I own both and personally prefer the single output.

If your bulb size is H8 should be good. I like the ouput of the cree led. Better price tag than the lux angel eyes thats for sure.

We have a bunch of these things running slightly more than 100 Cree LR6 modules and they work great as long as you can provide a load of at least 40-45 watts; anything less than that and the dimmer becomes unstable and you get noise and bad disco lighting effects (I'm pretty sure the modules don't like it, either).

cree led's shut off @ low voltage thresholds. what that is would need to be measured or ask the manufacturer

I'm planning to use a 9v battery to light up 2 or 3 of these LEDs; I see F. Solano has used a 200ohm resistor to accomplish similar, but Kapowzer claims a 1k resistor? Any advise re: which to use would be appreciated - thank you.

My Cree led bulb was bought as a 40 watt equivalent and I believe it is. The packaging states it is a 40 watt equivalent and no mention of 75 watt. It is being used to replace a 60 watt halogen that my wife claimed was too glare y and is a soft light as claimed on the package. My wife is happy with it. Is it possible a a 40 watt version was shipped instead of the 75 watt version or the "AD" had the wrong part number.

This is H11 compatible type bulb.Amazon matching isn't perfect all the times. This is generic brand and one year standard warranty is provided. Yes, It is cree LEDs. Thanks

The Cree LED has a usual lifetime of many thousands of hours of continuous use. The casing or circuitry is more likely to fail first.
