Bosch 18V GLI 18V-4000 C & GLI 18V-10000 C Professional Worklight

Bosch has two new compact yet high output cordless 18V lights with the Bosch 18V GLI 18V-4000 C and the GLI 18V-10000 C Professional Worklight. Respectively theyse tiny guys put out 4,000 and 10,000 lumens respectively. All credit for the info goes to instagram user ToolFreak.

These lights appear to be incredibly small, just big enough to hold a Bosch 18V battery with one high power LED chip on the exterior. Both appear to be identical with the only exception being the LED chip and lumen output and both had solid metal bodies shielded with shock absorbing rubber frames and roll cage style safety bars to protect the lens. It also appears they have bluetooth connectivity as it says it’s fully remote controllable via the mytools tile in the toolbox app. Runtime at max is up to 6 hours on the 4000 lumen model and up to 2.5 hours on the 10000 lumens model and that’s with a 12.0 ah battery pack so expect less runtime with smaller capacity batteries.

Edit: 8/6/20

Bosch has also come out with bluetooth connected versions of these lights model numbers GLI18V-10000CN & GLI18V-4000CN and these models offer Bluetooth connectivity – connects tool to free Bosch Toolbox app on a connected device, to turn on/off and adjust brightness.

A big thanks to Cody Robertson and Stephen for spotting!

Jesus christ, ten thousand lumens? I have the 18V light with 1,900 lumens, and that’s pretty bright.

I wonder why the safety bars and adjustable foot are different on these two lights?


I’d bet it had to do with heat-sinking design and needs. 10k it’s crazy, hell 4k is going to be demanding on something that small.

Would love your thoughts, please comment.x
