Default new flashlight questions

hello everyone, i just ordered this flashlight!
http://www.shiningbeam.com/servlet/t...CREE-Q5/Detail

i ordered it because someone on candlepowerforums.com said that it was a very good flashlight. they did readings and found it to be 30% brighter than the cheaper version on dx! here is the dx version:
http://www.dealextreme.com/details.dx/sku.7999

i decided upon the first one because A.) it is supposed to be way brighter and B.) they are located in new york versus Hong Kong

if you have either of these please share your experiences with me so that i know what to expect. when it arrives i will do a review on it and post videos and pictures!

Good choice! I would have gone for the RC-G2 personally but the F4 is pretty damn good. Next go for a P7, or an R2 w/ decent-sized reflector.

I have the DX version, and it must be putting out around 190 lumens - it is great

Default Re: new flashlight

what is the order of brightness of the led emmiters? (such as q5 p4)

What is the difference between lumens, candlepower (like in those 1,000,000 candle power spotlights) and lux?

Thanks,
Travis ( laserlover )

In ascending order:

P3, P4, Q2, Q3, Q4, Q5, R2.

Most common: P4, Q5, R2.

R2 is the most efficient and brightest but there's not a huge difference and some people don't like the greenish tint.

There's another LED called the P4 made by SSC. A U-bin SCC P4 can produce 200lm+. Also known for smoother beam pattern.

On a slightly unrelated note, LED's operate much more efficiently at a lower current eg 350mA. They max out at around 1200mA if I recall. Several LED's run at a lower current is better than one single LED run at a high current, because the higher you go the less lumens you're squeezing out per mA. Generally, single LED's with one deep reflector at a high current is better for throw, because it generates one strong hotspot. Multi-LED flashlights are more floody, because they produce multiple dimmer hotspots. The SSC P7, CREE MC-E etc are 4 chips in the one package to produce the efficiency of four LED's with the 'singularity' of one LED. *

how many lumens do you estimate this will produce?
