I found the Scangrip Star
Scangrip Star product page
as I looked for a work light.
I like the multifunctional form and the rotable grip. Magnets, rechargeable. 1000lm
A bit pricy.
Edit: Found a video
Does anybody know similar lights?
Headlamp with very floody TIR or mule, there are lights that have also a magnet and/or some magnets taped on the clip
Im with Lexel, the head lamp is very usefull, much more that “reflector” in that link because you dont need any hand to carry.
I have the skillhunt H03 with tir lens and regret for not buying erlier 
Well, I have 4 headlamps.
But for 5 to 8 hours work I normally rig up my light on a stand.
It’s much less hassle.
Check out the Loftek 15w light.

Me and my brother each have one. It works great. Has 3 x 2200 mah 18650 cells built in. Usb rechargable. Even has usb output like a power bank to charge your phone, etc… The light is very wide angle and smooth.
Charles BridgTec did a review on youtube. LOFTEK, PIONEER, 15W Portable Flood Light! - YouTube
Yeah, a floody headlamp is the best work light.
