I enjoyed your review, lots of useful info, thanks.
I agree Simple ceiling should not be 150/150… I set it to 110/150 which is about 250 lumens.
I like Advanced ceiling as it comes at 120/150. You can also go higher by using Turbo, although I dont think Turbo makes any sense because it drops like a rock very quickly, to a level below 200 lumens.
imo it is actually metal, Ive had it apart and it feels solid and heavy like metal.
the way I avoid frying it, is by not using Turbo.
I like to raise the thermal ceiling to 50C, it makes the sustainable output a bit closer to 300 lumens.
you can get the flashing adapter from gchart if you are in USA or from thefreeman if you are in Europe
this is a very good reflashing tutorial, if you have an Android phone:
