Is this possible?

Recently I purchased a Ridgid combo 18v cordless tool set.

One of the tools is a 18 volt flashlight. I like it's construction and form, but I'm hating it's light bulb. So far I've gone through 4 of them. They seem to be extremely fragile and the slightest jolt will knock 'em out.

It's an 18v 6.5 amp bulb, #780204001.

Can anyone suggest some way for me to outfit a LED(s) as a replacement?

I'm pretty handy with physicals mods, but nnot the sharpest when it comes to electronics, but if need be I can make things work, given some guidance.

So, anyone offer any ideas?

Thanks!

Hope you find what you're looking for and Enjoy!

simplest mod would be to replace the bulb with a Luxeon Star 1W or 3W and wire it in series to a resistor that you must add. The light must have sufficient space and can withstand some heat. To step down the 18V to ~4V for a Luxeon will produce some heat.
A step-down driver circuit is more efficient, but sounds like the light gets rough treatment. And the board may not take to shock well, whereas a simple resistor would.

Another alternative is to run 4 luxeon stars in series to take advantage of the 18V source. Still need a resistor to limit and safeguard the LEDs, but boy will it be bright!

They have a lot of data and a resistor calculator to assist you in wiring stars.
