The main attribute for these bulbs is their brightness. They are bright white and do a great job of illumination, better and brighter than a standard 60 watt incandescent bulb. Very pleased -- much brighter than our existing kitchen fixture bulbs.

It looses its brightness to almost null. However, the bulbs are noticeable smaller in the actual bulb shape.

Leds are much much brighter than the cfl bulbs they replaced. They look/feel like incandescent bulbs but much more energy saving.

K temp is lovely in the backyard. No problems at all through freezing midwest temps or storms.

These are listed as 150w equivalent bulbs, but at best are about 90w, a very dim bulb for an outdoor flood. The ones that worked appear fine, but one was doa.
