These bulbs are of incredibly poor quality. The light given off is just fine; a blue-ish hue, equal to about a 20 watt incandescent bulb. To the point: the craftsmanship of this item is shoddy. One bulb didn't make it through a single day, let alone the "ten times longer" promised in the description. For the cost of this type of bulb, the claims should be rock solid. Of the pair, the one remaining, functioning bulb is still going strong after 1 week, but I am unable to tell why the failure of the first bulb occurred. Based on this 50% chance of failure, I'd say this item is not worth your money. Go to a better-known and better reviewed company than "GRIP" for your energy efficient lightbulbs (they should probably change their name to "gripe")! I was foolish to purchase a lightbulb which is not UL listed. Please learn from my mistake. If you want an LED bulb, go with something that is UL listed and FCC approved, like EarthLED EvoLux.
