Nice light, but not that bright for the money I bought this because it said it was super-bright and it was 12 volt; wanted it for 12 volt solar charged system in remote cabin. It is hard to turn the inside to get it to mount, had to call Seasense who was very responsive; had to use pliers to get the inside to start to rotate. The listing for the product does not list lumens–amount of light. This is around 80 or so lumens I found out from Seasense. I checked its functioning with 12 volt and it is bright enough to read a book in bed only if the surface mount is close to your head. It is relatively bright but will light up only a small area of a room. There are other LED’s over 600 lumens, much, much brighter, for close to same price, some 540 that are a little cheaper. The big advantage is waterproof in a marine/boat environment, and it seems made well–but I don’t need waterproof–it is for a log cabin–I need brightness on 12 volt system, expected this to be quite a few more lumens given the price and given the desription “Super Bright.” I asked Seasense–“Super Bright” does not refer to how bright the light is–but is a rating given to the type of LED’s used in it. That said, if you want a good accent light, this is made well; but if you want a bright LED to light up a good part of the room and spread the light, like most LED’s except newest bulbs, this won’t do it. It is very good I suspect for a boat cabin, which is small and needs to be waterproof and corrosion proof if on salt water. For cabin or shed lighting, it is not too bright and is more expensive than alternatives–which need not be sealed with epoxy and 100% waterproof. Relative value for money for my application is not good, I can get more lumens in LED for less than half the price. I can more than quadrouple the lumens for slightly lower place but that is for a bulb would need a $ 2.00 ceiling fixture, making price about same. Company is good, tech service phone call was immediate and informative response, quality high for marine use. Thus 3 stars. If this were a non-sealed, non-waterproof unit for under $ 10.00, I’d give it five stars. Value for money for my use brings it down to 3 starsl Shed solar lights are brighter I think–not sure of their lumens, but they don’t light up much area either and only last a couple of hours unless you replace the nicads with much higher mili-amp NiMh batteries.
