Also, I own a cheap chinese 50W HID, Less than $400 RMB(Yuan)
Runtime, about 30-45 minutes, uses Lead acid battery
Damn well like it but too bulky, 7" reflector and weight over 2kg
Just a toy/shelf queen, not bringing it out unless in case of emergency
Quality, acceptable but not dangerous light
My previous wallmart-range flashlight wit a P7 in it (Trustfire SSC-7) works like a charm and gives a lot of light for a reasonably long time (90 mins) before dropping out on one 18650.
So, I thougt: what the heck!, and ordered a Fandyfire stl-v2 for less than 40 euro!!
After seeing the disassembled unit I was very enthousiastic (just look at DE and search for this light)
Also starting a test with 5 x XM-L in series with a dedicated 3000 mA conlux driver made for using continuously.
Bought the reflectors for some buks each at DE and use this combination to light up my 80 square meter livingroom that is surveilled by 2 x Axis M1054's.
The nice thing about this type of IP-cam is that there is a switchable output that can be operated, logging into your ip-cam's website at every place in the word :-)
