Wouldn’t using T13 be easier? It’s already in series, 8.4V, but similar head and reflector. No need to mod that.
Heck, you might even use T13’s stock driver with only resistor. As far as I know it will buck voltage to match amperage, so 6.0V should be easy to get from its 8.4V supply.
Yeah, the T13 would be easier, and you might get the stock driver to do it too. I do not have one though.
Also, I wanted a (jacket) pocketable flood light with some throw left over in a massive spot. Worked out perfectly for me.
It looks a bit more neutral in person. I consider the tint slightly cooler than a Nichia 219.
This light is very useful. The spot is huge so as a medium range searchlight it works well. It cuts through haze so the beam itself isn’t in the way. The spill is great, nicely even and wide.
It looks like you’ve created the perfect compact flood monster. I love your driver mod. How long can you run it on high before it gets to hot or the cells start to sag?
I forgot to add that to the post. The driver has thermal protection, so it steps down after about 5 minutes or so. Without the resistor mod it should go longer.
I will do a thermal test tomorrow and update the post.
This light is very useable on medium, which would run for about two hours.
Came out great! Good idea, Great Job relic38! I thought I might not be the first - the T08 has a nice size reflector, 2 batts, cavernous driver area, good heat sinking, exc. host for this, or experimentation. Just finished a de-dedomed XM-L2/SinkPAD high amp T08 - came out well.
