With a flashlight that uses a direct driver like the D1S you need to add resistance, by using a high resistance battery (the GA is still too low resistance/high current perhaps a NCR18650B works) and using long thin led wires if you can get the driver out. If you are handy and smart enough to find a spot for it, you may be able to add an actual resistor somewhere in the current path. Unfortunately Hank’s springs are very low resitance, maybe swap the copper-alloy tail spring for a steel spring. Experiment, keep measuring current and see if you can get to 5A or lower.
I asked him refarding the d4s already. He said the beam doesnt look right. Would be awesome if he can get them in the meteor though. Love the focused beam.
Also Hank, please sell the oslon white centralizers on your store.
If you use the gasket does that mean you don’t need to focus the led? I just ordered a gt mini and flat 1 from L4P a few days ago. I’m thinking I might have made a mistake.
