Ex Input:
Ordered this case but two whole packs (4 individual) were rotten. I could even smell it right through the cover. At first I thought there must be a puncture of some kind but could not find any. So knock off 2 or more and that is how many one gets for the price.

Ex Output:
3

Ex Input:
Great for recessed or track lighting Dimmable LED White to Color. Doesn't produce Green and Cyan well but other colors are good. These also come in PAR models also (with pins on bulbs) For table lamps I recommend the A19 Hue models for a natural look.

Ex Output:
4

Ex Input:
I can't say that this flasher didn't work, because it DID work as far as slowing the blinking. However, it made the most horrible screeching sound. Sounded sort of like an angry old cat with an irritating scratchy loud meow! I had to take it out, bought another brand.

Ex Output:
