Bosch GLL 100 Green-Beam vs Bosch GLL 2-15 Comparison Test and Review


Bosch GLL-100 vs Bosch GLL 2-15 outdoors on an overcast day in the buildings shadow.
These lasers were set up 7 feet from the wall.
The arrows point to the crossing point of the respective beams.

My trusty Bosch laser level is a great thing but it just doesn't work in daylight. I'm always waiting for dusk to use it on outdoor projects. I've heard these new green lasers are better, and the manufacturers advertise them as 4x brighter. So I decided to get one and try it.

Outcome: The new Bosch GLL-100 is not much better than my old GLL 2-15. And it is much larger. I will not be keeping it. Note the attached photo, taken on an overcast day in the building's shadow. The green laser is just barely visible, a bit better than the red laser. But still not usable outside. If you are using this indoors and do not mind the size and price, or just need a new unit, it is great. But I wouldn't recommend it as an "upgrade".
