Question: My contractor initially installed the commercial version then switched to retrofit.  What are the differences? Is one better??
Document: I bought these for a new kitchen remodel. It took awhile before my contractor could to the work. When he went to put up the replacement lights one kept blowing and would not work. The return was refused as it had been too long. If you buy these make sure you try them right away.
The light has excellent light output, but I'd argue that it's not 3000K. I'd guess that it's more along the lines of 4500K. However, I do like the cool color better than I would have expected.I installed 3 of these in my basement bathroom when I remodeled it, and they work great on a dimmer.
I bought these lights on the basis of some good reviews. I remodeled my living room recently and installed Cree LED recessed lights. I have been very pleased with them. These Halo LEDs appear to have similar specs to the Cree, but they sure don't seem like it. The Halo lights are not as bright, and they seem whiter and cooler. The Cree had a better spectrum of light, in my view. The Halos will do the job I guess, but it will take some getting used to.
With great expectations, I ordered two of these as a trial. Even though they were nominally the same fixture, they were different in subtle ways. There were subtle diffences in the description on the packaging, for example, 3 year warranty vs. 5 year warranty. One was a newer model than the other, and, after researching it through the manufacturer, it turns out that neither one was the newest model. One worked pretty well (the older model).
Awsome if I had more to retrofit I would buy more instantly have to get more just for back up. Thanks Would recomend to all people who own floresent halos.
They give soft, bright lights and can be deemed. They are also better than comparable LED lights made by Halo.
Good light output. Dims fine.We've installed other LED lamps and recess light trims throughout the house and it has made a dramatic difference in our electric bill ! Couldn't be happier.
These updated Halo RL560WH-R fit much better in a 5" can than the old Coopers. It also seals against the ceiling much better.They also seem to work very well with dimmers, and dim much lower than the Coopers.I am very satisified and they are easy to install, about 5-8 minutes each.My only complaint is that the price seems to have gone up about 10$ in the last week.
I installed four of these in my office, and really like them (RL560WH-R). My only gripe was how very frustrating it was finding a compatible dimmer. I tried dozens of Lutron's CFL/LED dimmers and all of them either buzzed, had delayed start, or both. The closest was a standard non-CFL/LED Maestro dimmer, but still a faint buzz.
Unless it's just me, they really should make that more clear.
Answer: no
