Customer Questions & Answers

What does tool only mean?

Asked by: sunshine2076
No battery or charger is included. This is typically an add on to other tools a user may have. However, you can purchase a battery and charger separately (you just pay more).

is this available in the store?

Asked by: Anonymous
Maybe. Just try to buy it online and schedule instore pickup. It will show available now - which means they have it, or pickup at a later date - which means that store doesn't have it. Try another store.

I have the M18 2Ah battery - how does this worklight perform with this battery? Most of the reviews seem to be for 4 Ah battery.

M18 18-Volt Lithium-Ion XC 4 Ah Extended Capacity Battery is rated 4.6 out of 5 by 93.

Milwaukee makes some great M12 and M18 LED lights -- this one is NOT among the best of them. This one came as a free bonus item during a November special. Separately, I would not recommend paying more than about $20 for it. It does give moderate blueish-white light enough to see what you are doing, but not very well. It does seem reasonably well-made as are all the Milwaukee tools, and I don't doubt it's ruggedness or reliability. But the quality of the light just isn't very good -- it's got that "early LED blueish light" look which makes it hard to see things clearly. The beam isn't focusable, and just not that bright since you can't focus it onto a smaller spot. In comparison, the Milwaukee M18 2352-20 is an Amazing LED light, though much more expensive. It advertises "natural light" and compares it to how "bad" LED lights can be. It's true, that expensive model gives you full-spectrum light that looks, like, frankly, the old incandescent shop-lights you'd screw a 60-watt bulb into. It's a lot of light and you can clearly see things and make out colors. It also has a high-low setting and two retractable METAL hanging hooks. I'd bought that separately, about a week before getting the "free" 2735-20. So maybe it set my expectations too high. Basically, the light from the 2735 looks like the example of the "bad" LED light that the 2352 uses on it's package as "what not to get."

Its light and bright, the construction of it solid and the hook to hang it comes in handy. I got this as part of a kit, but I have to say as much as I like it I'm not sure id pay the $50 for it. That seems kind of steep.

Rated 5 out of 5 by from Works great Have had close to 24 hours of run time off a 5.0 battery and the gauge still shows a full charge. The light is bright and has a nice feel. Only thing I think they could do to improve it is make them accept the milwaukee belt clips on the side like the drills and impacts
