Earthmate EP3057AE 30-Watt Spiral CFL Full Spectrum Bulb, 6 Pack

These lights have exceptionally good light output. I bought these 30 Watt bulbs, but they were a little too bright when I used them in a light fixture with 5 lamp sockets. The 23 Watt bulbs I purchased afterwards are still rather bright in the same 5 socket light fixture, but acceptable. The light output will become a little less with time. These 30 Watt bulbs are excellent for a three lamp light fixture. When compared to an incandescent bulb, these appear to be pure white and the standard bulb a weak yellow glow by comparison. Once you adapt to these full spectrum bulbs, you cannot go back to standard incandescent bulbs. Now I am replacing incandescent bulbs in all areas of my new house except in areas of low usage or places the bulbs will not fit. These bulbs will fit in most fixtures, however. I am replacing the fixture in my garage to put some 45 Watt full spectrum bulbs into a cluster light fixture. I live in the Houston, Texas area so cold weather is not normally a problem...Read more

I've been a user of full spectrum bulbs because my office is attached to a computer server room and thus has no windows. I use this lights with a few desk lamps that I aim toward the walls/ceiling from my wrap around desk to provide some natural feeling light. It really helps me feel less like taking a snooze under all of the dim indoor lighting.

The packaging was all cardboard and contained no plastic. The bulbs seemed very well protected and I had no issues with them being shipped. I will definitely consider these again the next time I need more full spectrum bulbs. Also, no flicker that I can notice.

The dimensions of the bulbs are:
15-watt: length: 4.37", diameter: 2.06"
23-watt: length: 5.04", diameter: 2.44"
30-watt: length: 5.16", diameter: 2.76"

All bulbs in this line are 5500K with a CRI of 88.
