Question: Does the head swivel up and down or sideways?
Document: wow! I was VERY surprised at how much light this puts out. I installed 2 of them on my outdoor shop and am very happy with the amount of light they put out. Time will tell if the leds last a long time. Highly recommended so far....
When my wife saw how small this is (the whole fixture is about the size of a gallon container) she expressed doubts if it would do the job.
We had some issues near our home with people  stealing our front porch lights so I wanted to install some security lighting around our home. I debated between motion sensor lights and dusk to dawn. After thinking about it long and hard, dusk to dawn won out. I live in a neighborhood so I had to ensure the light didnt hit my neighbors home. This light is easily aimed and angled to accomodate that need. The product works perfectly and has been working now for a few weeks without a hiccup.
Very bright light, was concerned with LED being bright enough and this is brighter than the lights it replaced, dusk to dawn sensor works great. Very well made unlike other products I looked at. LED expensive, but we installed ours high up and who wants to change bulbs, not having to do one bulb change is worth the price let alone energy savings. Can't go wrong
This worked very well. The light will also work on various recessed boxes. The photo control works well; the timing may be on a bit early, but at the almost negligible power draw, who really cares?! This light could remain on 24 hrs/day and still cost far less to operate than the old ones. I have just ordered another for the neighbor......
The light replaced a Par Flood light fixture that was 150 watts. This light is substantially brighter albeit a bluish white light from the LED. Buy with confidence.
Replaced 500 watt halogen with this unit. It's brighter and clearer. The halogen was a motion detection unit which never ran properly. I have this over my driveway and it illuminates 30+ feet to the road. Installation was a breeze due to pre-existing wiring and mount. It's mounted about 15-20' high.the dusk till dawn feature works without troubles and the LED bulbs pour out true white lights.
Please make sure that you follow installation guidelines. If installing under roof overhang, make sure that sensor faces in opposite direction from light. It is also very bright so installing it higher and away from people is suggested. Sealing it after installation will help to protect electronic. Very good light and takes1/5 of the energy of light bulb.
I purchased this floodlight a few months back to replace an old one for the driveway leading to my garage. I am very happy with it. It is very bright, and I appreciate that for security. The light is fairly far on the &#34;blue&#34; range, which may be off-putting to some, but I have it in an area where there is no traffic except for me pulling into the garage from my alley.
I am waiting on my Electric bill to see the per month cost verses the halogen unit.I am buying another for my shed!
