Does the job
Your review: We have a large plant and a lot of emergency lights. So we have a big disposal problem with the lead acid batteries. I was looking for an alternative. These will fit the bill. I still have to dispose of the Ni-Cad with a service but the size means less frequently.
Since these have only been in service less than month I am uncertain about when the batteries will fail the monthly tests we perform.
Pros: Look good. Function well. No lead Acid batteries.
Cons: I have a lot of the Lithonia lights and had hoped that the base was the same. As that would make the change out very simple that was not the case. Different bases.
