5 minute 30 second fan cooled with GA cell at 4.1x volts. I make no promises of the accuracy and in fact I don’t think the percentages are accurate but i’m hoping the overall shape is. When I pulled it off the box the SST-20 lights were in the 320-360 lumen range which doesn’t make sense given the percent stated.
I used my old integrating shoe box and my Galaxy S10 with ceilingbounce app. I haven’t really used the app on this phone or the shoe box in a long time so I cant really trust how either of those work.
At the end of the test I stuck them on my own somewhat calibrated DIY sphere just to have a more accurate measurement at the ~5-6 minute mark
I just received my FW3C polished, Cree XPL Hi 3D and it does not work. It sure looks and feels nice though. I ordered it through Neal’s site.
I have read this entire thread.
I only get the flash when the battery initially makes contact. I have tried several different unprotected 18650s that are all at a little over 4 volts. They work fine in other lights.
It has a brass driver retaining ring and a black switch retaining ring.
I tried loosening the driver retaining ring to make sure the driver was centered. I also tried it without the ring installed.
The solder joints on the MCPCB look fine.
I held a battery to the head and completed the circuit with a piece of wire and still only got the initial flash.
Is there anything else I should try?
I sure hope I do not have to send it back to China.
I was going to order a FW3T with the same emitters, if I liked the tint of the XPL Hi 3D. I am now going to hold off until I get this straightened out.
I have not reached out to Neal yet. I will do that shortly.
take off the head and tail. You will see a circular copper contact point on each, wipe those points and the springs with a swab dipped in alcohol. Problem should be solved,
Also wipe both ends of the tube.
Remove the clip, sometimes the tail is not screwed all the way down
don’t worry, it will work. They all seem to do this
