I had the older Bosch light (the GLI18V-1900), which is much heavier and bulkier than this light. I still use it at home, in the backyard when we're playing games in the yard (cornhole, Bocce ball, etc). I love that this light connects to your phone. You can turn it on and off and control the brightness from your phone. I connect this light to the ceiling grid with a zip tie when I'm terminating cables in a rack or cabinet, so it's nice to be able to turn it on and off without having to get up on a ladder.If you are like me and end up having this on all day, I strongly suggest you get a couple of the big Core 8 amp hour batteries to use in it. I can keep this on all day (on the high setting) with 2 to 3 battery changes if I'm using the 8ah batteries. I just take the drained one out, put the other one in, and pop the drained one in the charger... rinse and repeat. A long day might require 3 -4 battery changes. but considering how incredibly bright this thing is, that's really amazing. If you lower the brightness, you can probably get through an 8 hour day using only one Core 8ah battery. If you are going to have it on the brightest setting and use it all day, you'll need 2 8ah batteries, and your charger to keep it going constantly.While this tool does have Bluetooth built in, it does NOT have a geofence feature that will remind you if you leave it behind (nor does it let you know where it was last located, although it does tell you the last time it was connected). So, I attached an Apple Tag to it with a rugged tag case that sticks to the light using 3M's VHB adhesive (I have a bottle of adhesion promoter that makes the VHB stick like a champ to most surfaces). That way if I forget it (which is easy to do when you're packing up and just forget that I've ziptied it to the ceiling grid) the Apple Tag alerts me when I drive away (the Apple Tags have a nice geofence feature that does that). I wish Bosch would include a geofencing feature, or at least let you know the last place your phone was connected to it. Some other commercial-quality toolmakers are including that feature, and it would be easy to do with the Bluetooth being built in these devices or available separately in a little Bluetooth module that pops in the newer devices (like the newer drills and chargers).That aside... it's a great jobsite light that is really bright, well-constructed and pretty lightweight compared to most other portable lights of it's type. Bosch has upped their game in the last couple of years and that makes me really happy, because most all of my portable tools are Bosch. Most construction guys are monogamous to one manufacturer, because we don't want to haul around 2 or 3 types of chargers and dozens of different batteries. So, it's nice that they've recommitted themselves to keeping up with the Yellow, Red and Turquoise competitors (you know who they are).There is one more reason - maybe a little quirky, but still a good reason - is because most guys on jobsites are Yellow or Red tool devotees. Not a lot of construction guys in the States have all Bosch tools, unless it's vacuums or demo hammers, which most construction companies prefer (especially the demo and hammer drills, of which Bosch is the best). That means that those few bad apples who have sticky fingers and like to add tools to their collection that they didn't buy (meaning they steal tools from the jobsite) aren't as tempted by Bosch tools, because they don't have the charger or batteries for it. In the past, fear of being stomped into the concrete kept guys from stealing tools, but nowadays (in our kinder and gentler world) that fear isn't as prevalent. So, it's nice that Bosch tools aren't as attractive to them as the Yellow, Red and Turquoise tools are (because lots of guys buy their tools from Home Depot, that stocks the Red, Yellow and Turquoise tool brands, but they don't often carry Bosch, except for demo hammers). I live in Texas, and tools rarely get stolen off jobsites here, but when I travel to some other places (which will remain unnamed) they walk off frequently, but Bosch tools aren't as attractive to these thieves it seems like. Dunno if they're harder to pawn or they just don't have the charger and batteries for them, but Bosch tools are stolen far less, in my experience (except for the demo hammers, thieves love Bosch demo hammers). Anyway, I'm rambling. This is a great light! Get it!
