Rated 4 out of 5 by Hospiceboy Bright light, not so great longevity
This bulb provides more lumens at a lower cost that incandescent bulbs. However, these bulbs do not last as long as expected for CFL bulbs, probably due to the heat that develops in the canister.

Rated 5 out of 5 by Paul65 Good product , good customer service.
Installed 8 for these bulbs in a large room(16x30) used for Quilting. Good color, great light.
One of the bulbs failed after only a week, customer service immediately (less than 3 days) sent a replacement bulb.

Rated 5 out of 5 by Pawnguy This is a 6500K Bulb
This is a great very bright bulb strong white light but it really shows a 6500K blue hue. I bought this and a 4100K bulb which looks more like a 5000K bulb but if you need a really bright bulb this works but in my opinion it shows too much like a 6500K.

Rated 5 out of 5 by Denny Excellent Product With an Excellent Price
I have used these for about 4 months now and really like them. These are color rated at 5000 degrees Kelvin wich is equivelant to sun light. A wise choice if you want to see things as the color they are or take pictures that are not tinted yellow. Another nice feature is that when you flip the switch the bulbs come on dim and reach full brightness in a couple minutes. Nice when you first get up in the AM, you are not blasted by bright light! They are very bright after warm up and the diffused lens leaves very little shadow. I will buy mre of these later.

Rated 5 out of 5 Highest Wattage CFL Floodlight Available
I have installed over 40 of these bulbs (and the 2700K Warm White Version) in both base down and base up applications in the last three years. Four have failed so far. They are the highest wattage CFL floodlights I can find. They have a very wide, even light dispersal, wider than halogen and incandescent floods. I have noticed a very faint harmonic buzz from a few of the bulbs, but only those with very sensitive hearing would be bothered by it. These bulbs do require 3-5 minutes to reach full brightness.

Rated 5 out of 5 by stevenyc1 5000K Full Spectrum
I have been using three of these lightbulbs on a tracklight in my livingroom for the past eight months and love their 5000K full spectrum light. No problems so far. Their quality prompted me to order a set of spares.

Rated 4 out of 5 by Stephenjt1x Good Illumination replacement for R40 150 w
At first I was not happy with this bulb as it has a high pitched whine at power on, but since I am 60 and my hearing is not as good as it used to be I got quickly used to it. Younger users might find it annoying. Good amount of lumens
