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.
I was just thinking about how to add resistance in the D1S with 2mm^2 white flat. Is there enough clearance with the reflector for some 1 or 2W resistors in the head to the side of the MCPCB? You could attach them to the head with thermal adhesive to make sure they don’t overheat. For the 2mm white flat you need to add about 0.1 ohms to get the current down to 7A or so, so they need to dissipate between 4 and 5W.
