P7 led

[Deleted member 8178]

No way that's a 30W emitter, 3W or 5W I might believe.

well it is 30Watt.. as it was advertised

 

[jayrob]

They must have meant to write 3.0 watt...

Jay would know fer sur plus thats pretty small to be a 30 watt my 10 watt is twicw as big

lol now im confused hehehehe anyway, im thinking if this will not work good with P7 i will convert this to a GREEN LASER

I don't know... Does Luxeon even make a 30 watt emitter?

Anyway, if the light is really putting out 600 lumens, your not going to get a whole lot brighter with a P7 emitter and 4.5 volts input...

Before trying to modify that light, I would buy this P7 light for $35 bucks and compare brightness:
DealExtreme: $35.00 SpiderFire SSC P7 SSC P7-C 2-Mode 900-Lumen LED Flashlight with Strap (1*18650)

This seem the more powerful single-emitter luxeon led

Luxeon K2-TFFC LED - Cool White Lambertian, 220 lm @ 1000mA [LXK2-PWC4-0220]

They have also more powerful ones, but are tri-emitters.

The original light was 30W, with an incandescent bulb. Now matrixcs wants to replace it with the 10W P7 quad-emitter LED.

The letter/number combo designates the efficiency (in lm/W). P7 is an older one, with ~90lm/W. Q5 is the current standard for high-quality flashlights (~110lm/W). The current best, but difficult to get, is R2 at ~117lm/W (in each case, there's actually a range of values - all LEDs that fall within a range are put into the corresponding "bin"). There are different sub-designations for color temperature.

End of last year, there was an announcement of a 150lm/W Cree emitter (which would probably fall in the "T" bin once it starts being mass-produced), but I haven't heard any more about it (didn't try to follow it either).

what is the brightest LED out there in terms of lumen?

Is 7000 enough? 100W ebay LED

Wicked torch

I don't understand how it can be 4100 lumens. Halogens are 30lm/W at best, so the WL torch should be <3000 lumens.

From Ebay Page:

"Forward current: 3500mA
Forward voltage: 32-36V"

Where would you get that kind of driver? What batteries would be suitable to power it with?

The Wicked torch relies on the IR light as well to generate heat. It may do like 900lm or so of visible light, but how much IR is anyones guess.

I don't think the wicked torch uses a 100W halogen, last time I checked it was 50W, unless they have upgraded.

I bought a 1x18650 torch off DX with the SSC P7, the best torch I have ever bought

The SSC P7 is rated to run at 2800ma, so a single 18650 isn't really up to the job (for any amounts of time).

Its price tag is as big as the LED

You don't understand. Lumen is a measure of brightness, not power. 1W of 532 light has 600 lumens. 1W of 660 has 41 lumens. 1W of 1064 light has 0 lumens.

So it's not even possible to have the other 3200 lumens as IR. That's like saying I weight 32 gallons long.

now im a bit more confused.. hehehe i will just buy a p7 and put it there...

That website had a lot of information about the 100W led. That focusing lens was awesome. It looks like it would be a really big flashlight though.
