Question: and does this light need to be put in a can?
Document: So as a contractor, I am unable to use them. That is a shame, because I think they are really cutting edge. They advertise 12W as equivalent to 90W, I was skeptical, but...  Thy are VERY bright and surprised me! I put it next to a 14W 6&#34; retrofit, this blew it away! Not sure how a 14W can be advertised as 60W equivalent and this a 12W is in fact brighter. Maybe  need to read up on light rendering.
Definitely worth the investment.6.) Electrical installation. I had intended to install a single transformer and then run low-voltage wires to each light. However, as mentioned above, the lights have odd electrical specifications requiring you to use the transformer that comes with the unit. This changed my installation plan somewhat because now I needed an electrical box to house each transformer instead of one electrical box to house a single transformer. According to code, you need to put high voltage junctions inside a junction box.
I purchased a handful of these lights to put in my soffit to illuminate around my pool area. Super easy to install and work GREAT! They are extra bright when you need them, but can be dimmed down to give that nice glow you want for accent lighting. I definitely plan on buying quite a few more of these to install around the rest of the perimeter of my home. I was definitely super impressed for the price and what you get.
However, upon inspecting the lights I saw they required special transformers that put out relatively high voltage DC. The lights come with this special transformer so this isn't a big deal - just unexpected.5.) Mechanical Installation. Installation is quick with a 4.25&#34; hole saw. Please note that you'll need to expand the hole in a few places to make room for the retention clips. If you don't want to do extra work, get a 4.5&#34; hole saw.
These lights have been installed in our home on dimmers and we love the output. The color is a true warm white, not yellow and if you put enough of them in a room you get a nice natural light setting. Most importantly is the reduction on your energy bill. Easy to wire, easy to install.
We bought these lights for a remodel job in our townhome. We have them in our kitchen, family and living room. They offer great lighting that is dimmable and the price can't be beat! Our contractor couldn't believe how easy they were to install and how much light they put out even though they have small footprint.We are very happy with our purchase!
The light is bright white, not unduly &#34;blue&#34; and the light from two units matched perfectly. Runs warm, not hot to the touch. I installed two units over a standard tub/shower and the light is bright and even. Did not put on a dimmer so I can't comment on that.
These lights are good quality, dim nicely, will supposedly last a very long time, and put off a nice light. I couldn't be happier. I should add that these lights are a bit warmer color temp than I expected. I am putting them in the basement and thought that 3000k would be a little closer to white daylight. But these ended up looking fairly close to an incandescent light.
Comes as two pieces. The LED fixture and a separate driver that plugs into the light fixture. For safety it's a good idea to put the LED driver into a metal junction box. If the LED driver was built in instead of a separate device I would have given 5 stars. The light is bright and evenly distributed. Much better than the florescent flood lights I was previously using.
These lights are not housed in a flimsy housing. I was very impressed by the weight of this unit. The light output is great as well, very bright. Great to put on a LED dimmer switch. The light coming out is a yellowish warm light, so 3000K. If you want more of a day light shine, find 6500K output. The one drawback I found was the wiring; if you're a handy person you'll be able to work the wiring with these lights with no problem.
