Question: Are they dim able?
Document: WOW, these LED bulbs are FANTASTIC! Don't hesitate to buy. They put out good light. I plan to get more.
This light is exactly what it looks like which is a spot light and does not fill the room with light. Furthermore, I would liken the light it puts out to a 25 watt bulb, not 60 watts as described. Last, the light it emits is too blue.
The light output from these bulbs is bright and clear. Unfortunately, the light beam is very narrow which leaves dark areas between beams. I tried bulbs in 4 bulb ceiling fan on a 10 ft. ceiling and also in flood fixtures in kitchen above island, 10 ft. ceiling also. The beams are so narrow that there were dark spots on island and room. This might work OK for very targeted display lighting, but not for general area lighting.
I purchased these bulbs for use in ceiling fans. Unfortunately the light output was anemic, less than the existing 40w bulb. That might have been okay but this bulb also focuses most of its light in a narrow beam. After putting the frosted glass canopy back over the bulb, there was minimal light across the glass except for a very bright spot at the bottom center of the glass.
I THOUGHT I WAS ORDERING THE 60 FAN VERSION OF THIS BULB.WHEN I INSTALLED THE FOUR LAMPS ONTO THE FAN THE LIGHT EMITTED WAS SO VERY DIM...EACH LAMP PUT OUT ABOUT ILLUMINATION AS A C9 OUTDOOR CHRISTMAS BULB...A SINGLE REGULAR 60W BULB WAS MUCH MUCH BRIGHTER THAN ALL 4 OF THE LED LAMPS.I BELEIVE U MUST HAVE SENT ME THE MORE LOWEST RATED BULB
Bulbs are being returned.
