So luckily this arrived the next day like it said it would!So installation was easy, the mounting bracket has plenty of holes for mounting. You do have to drill out the ones you want.After I mounted it, the battery had enough charge to test multiple times. The LED's are bright and the lenses are easy to move around.

These newer LED and nickel cadmium lights are lighter and last longer than the older incandescent and SLA units.

Great light output and runtime.

The saying "you get what you pay for" applies here. This is solid, high-quality emergency light. You need to have to wire it directly to an already installed electrical box; it is not possible to plug this into an outlet like a lamp. That said, it is not difficult to install. Instructions are helpful. This provides a lot of light - a total of 1100 lumens - and the three LED lamps are positioned so as to be able to illuminate your space in different directions. This is useful if you have several spots, like some stairs, or a potential hazard, you want to make sure is visible if you lose power. These types of lights used to really suck energy, but with the LED lights and newer tech, this one is very energy efficient. as well as exceeding the code for emergency lighting. In fact, it can be installed from 7.5 feet high to 30 feet high, which obviously goes into the commercial realm. The battery, which provides 4 hr additional run time, is lithium phosphate. There are a lot of cheap look-alike knock-offs of this kind of light, and the price reflects that. If you want a light that you can depend upon to work reliably and well into the future, this is worth the investment.
