Just rcv'd one of these SC04's - oh boy, two major issues:

  • it will not run on 1 cell, RED LED comes on, comes on low only, then flickers, then goes off - all in a few seconds. It's acting like the driver is not designed for one cell. It works pretty well on 2 cells, though I only measured 4100 lumens at turn on, Tom E hyped up lumens even, on 2 good LK 5000 cells
  • The LED's are not centered and found out why - the LED centering pieces are too small for the reflector holes so have wiggle room, and the LED's wiggle around in the hole of the centering pieces. So with the 4 separate MCPCB's wired in series, not mounted, just has thermal grease under them, there's lots of slop movement and positioning possible.

Awful design issues... More comments:

  • But I do have to say the overall quality of the light is pretty darn good
  • The LED wires are only 24 AWG coming off the driver though
  • I do like the feel of the switch
  • the bezel is smooth SS, not as pictured strike bezel design - the Ali store page shows 1/2 pics with strike bezel, 1/2 smooth - luv the consistency...
  • it's a nice compact size with just a one cell setup (probably go this route with a replacement driver, rewired LED's in parallel)

What are u guys doin over there at HaikeLite? Why are you trying to kill your rep like this? I don't get it....
