      Comments about Longstar 100W Incandescent Equivalent. 23 Watt, 120 Volt Daylight White CFL Bulb.:

      Great Bulbs, a nice pure white color and bright as I wanted. I will continue to buy these in various sizes throught my home because of the the wonderful daylight color. It's like being outside in the sun, no tint of yellow at all. I highly recommend these to anyone who wants to see pure colors reflected in their srurroundings. Even brighter than the GE 6500 K bulbs I replaeced which are not being manufactured anymore, for the same wattage!!!!! Also, the price was rigth in line with what I had been buying previously, so I received good value as well as a great product. Thanks Bulbs.com.....great job!

          When the bulb is first turned on the light output is at approximately 70-75%. It reaches full brightness within 20-30 seconds.
