Question: Can I use a dimmer with this light?
Document: I have a 70  W High Pressure Sodium light outside the barn. It works great, but has this orange glow. You know like most parking lot lights. I wanted something with more natural light, and used less power. This does the trick, the bonus - it is almost as brite. The unit is constructed well, easy to install and draws very little current. It WILL NOT work with a dimmer. Before installing it, I attached it to an ammeter and found the unit to draw about 18w.
We've installed 8 of these on our property. Excellent 5000+ Kelvin daylight white light. Not that horrid yellow. If you are thinking of a High Pressure Sodium instead, yes it will be cheaper at first - but will use more power and not last as long.
Since these are the type of lights that tend to get a lot of use so you can really save some money and better yet, help preserve our natural resources.
for a 500 W outdoor light. I will replace more exterior halide lamps with these. This is a good-looking lamp, well-designed.
This thing really lights up my front yard, even more than I intended but what the heck. More light equals more safety. Seems to be well made and solid, installation was a snap.
Like just about any other light sensing device out there, it comes on too early for me and shuts off too late. I wish these things were adjustable.6. Unlike the HPS, this light is directional. Where there is light is is as brigt but it does not shoot light up in the air.
Very nice look, uses only 18 volt per light and I bought 3 so ism using only 54 watts for all three, strong lumnes and it light about 30 feet by 40 feet of my driveway very brightly and sharply
The floodlight installed pretty easily and has been performing well. The only thing I would improve is the sensitivity of the photocell. It comes on way too early, I tried placing a reflector underneath the unit to gather more light and that helps, but it could be better.
I would have given it 5 stars, but I believe the sensor should be placed either at the top of the light or on either side. It is placed in an obscure location under the light. The sensor can be more &#34;sensitive&#34; to the lack of  light if the placement were different, I believe.
First off -- I love this light. At under $80 I decided to go with this Dusk to Dawn light to replace my CFL setup that was popping (due to low temperatures). I was hoping for a light over 4500 (Daylight) but this light is at 3978 at the upper edge of Bright White.
Answer: yes
