540 lumen 3 Rebel star mod idea. Good idea or not?

[light_emitting_dude]

Being on a budget I need a cheap host to put a tri rebel star LED in so I came up with this........

I want to put this.....http://www.luxeonstar.com/item.php?id=5537&link_str=1430&partno=7007-PWC-10-3

in this.....

A few thoughts..... After reading about rebels I am concerned that 3 rebels may generate too much heat and melt the plastic reflector. Also the reflector looks like it could be modified to facilitate the rebel stars 3 led.
I'm not sure exactly how many amps this SSC is driven at. I suspect around 700. If I pull it off, it will be a 540 lumen LED flashlight! Not sure if I want to yet, just and idea.

What are your thoughts and opinions?

Note that the tri-rebel star you linked to needs 9.45 Volts. The driver (If there's one) in light you start out with probably delivers about 3.2 Volts. I'm not sure if there's a driver available that'll deliver 700ma @ 9.45V with just a single 18650 or 2x16340's.

If it's solid under the star in that flashlight, I think it may be okay (not driving the Rebel too hard).

I'm thinking of using 3x10440 in a 3xAAA holder and use a resistor to direct drive the serial connected Rebel. The current shoudn't be too high, since 10440 doesn't have much power.

Thanks I missed that. Maybe a light with 2 18650's would be a better idea.

Sweet!
I didn't know they had those already.

I wonder if the 9.45 Vf is the maximum allowed voltage. I looked at the spec sheet and there is no input info. I guess the best way to find out would be to apply different voltages with a power supply to see if it lights up.

In Ebay I buy some time ago this driver, I think this can work for this Leds...

Let me know...

wait till they build a Rebel "V"

The seller, how make this drivers answer me this can work with 13 volts or higher power supply and connect the Leds in serie....

It would be a Rebel XVI.

I have tried the other PCB with three rebels where all the heads of the rebels come together. I have put it in a Mag host, but the three emitters don`t give a good hotspot. I have three circuits under a custom heatsink, for every emitter one circuit with about 800 milliamps to the rebels. I need to place them better under the heatsink and than try to put up some pictures.

Thanks for the info! I was wondering about the hotspot of the 3 emitters. Pictures would be appreciated!
