Question: Is this unit comes with Photocell button? Can be mounted on a 1/2" pipe? Thanks
Document: Well built 39 watt LED. I installed 50 of these as replacements for existing 500 watt halogens. The CRI is rather low, but they are just for security lighting and the energy savings is dramatic, 25000 watts down to under 2000.They are heavy, we had to drive a galvanized pipe behind them and use straps to stiffen everything up, as they are ground mounted about 18&#34; up off the ground.
really bright & lights up the yard well, wish it was energy star rated but for using only 39 watts instead of the 150 i had before, it i does a better job
While the cost was a little high, the investment turned out to be worth it! Since these worked out so well, I will be buying more of them and you can take it to the bank that RAB will be the only company I purchase lights from in the future
Using these light fixtures for our HOA landscaping lighting system. Have purchased several and will buy more. A lot less money that purchasing them through an electrican.
Installed to light up Basketball hoop. Does the job well and would recommend this light. I used bullets for our playground and in hindsight would have used these instead. Nice broad but focused white light with low watt usage. Light is heavy and therefore is a little more difficult to mount than a simple bullet.
Answer: no
