Question: Is it safe to use with a timer? I'd like to place this in the lanai when I'm not home.
Document: Very bright outdoor light, it uses only 20 watts. I replaced a 90 watt lamp with this and I'm pleased with the result. The only concern is that this one comes with very short wires which I replaced. No big deal if you've ever rewired a lamp. I use this as a yard light that is on for several hours every night. The savings in electricity is 74%. The payback is 2 years and the 'cool factor' of having an LED yard light has no price.
We like to customize our trucks/trailers/whatever.These lights were what we needed to do that.We will use this avenue for purchases again.
I wanted to illuminate a small parking area next to my home. I have it wired into a circuit controlled by an infrared motion detector and it all works great. The light is on the blue side of the spectrum and might be considered objectionable if one wishes to render colors accurately but it's fine for a security lighting system. I'd definitely purchase this again if I were considering a similar application.
i am very impressed these things i bought 6 of these and they are so powerful that i could not use them all or it would look like daytime around my house. i think i am going to use less of them and just save 2 of them for spares. these are way to much light for just accent lights.i think these are about 5 times more powerful than my 20 watt malibu landscape lighting.one of them was cracked on the housing that the small transformer is in.
The copper was so thin I was totally unable to use a wire nut (I tried over and over). I ended up tinning the wires with solder and using a terminal block to connect to my 12 gauge house wiring. It was the only way I could get a reliable connection.The screws have already started rusting, and it has been outside exactly two weeks today. I hate to think what it will look like a year from now.
Based on several reviews here I thought it recently came wired with a two prong power plug. It does not. I'm not interested in wiring this myself so I'm returning it. Can't evaluate the light quality.
I got this to reaplce the power-hungry 150x2 halogen security light that I installed after someone stole our grill last year. I'd say this is as bright as a 150 watt hqi metal halide fixture. The spectrum is pretty blue, but not too bad.
You save more then that annually in electric if yo run this all night like I do...
this light is amazing it is really bright and it doesn't produce any heat at all, i do really like it very much.
It's like looking into the sun and stays cool to the touch! I hope the led emitter last as long as stated.
Answer: yes
