I built a mini triple light several months back.
I recently got it out of my collection to use as my nightly use light but on high the light steps down after 2 seconds. I tried doing the whole 8 tap then the 30 taps then timing what i want for step down. Well that does absolutely nothing…I tried switching batteries too…the driver is brand new from RMM and the triple noctigon is 3 XPG2s @5000k driver has the 33 mode guppy
It sounds like it could be an earthing problem somewhere. I'd check to make sure everything in the tailcap, head and the battery tubes are all tight.
