Wow, these are huge!,

This review is from: Full Spectrum Light Bulb - ALZO 85 watt CFL 5500K - Case of 4 - daylight balanced pure white light - 4250 Lumens
I knew that they were going to be big, but I never imagined that they were going to be this big. I bought them for studio lighting but there is no way they are going to fit in any kind of household light fixture. They are very very bright and do the job perfectly.

Good Lights,
By djb (Redmond, WA) - See all my reviews
This review is from: Full Spectrum Light Bulb - ALZO 85 watt CFL 5500K - Case of 4 - daylight balanced pure white light - 4250 Lumens
These are very good, cool lights. Keep in mind they are much larger than a standard light bulb even though it has a standard socket. They are designed for video lighting fixtures.
You have to wait a couple of minutes for them to warm up to their full brightness and color, but that's not a big deal, since it takes at least that long to setup for production anyway. All in all, nice and bright, sunlight color balanced. Also keep in mind that they don't compete with direct sunlight. You'll spend a lot more and use a lot more watts to accomplish that.

Excellent Light, but still a little blue.,
By J.B. White (Austin, TX) - See all my reviews
This review is from: Full Spectrum Light Bulb - ALZO 85 watt CFL 5500K - Case of 4 - daylight balanced pure white light - 4250 Lumens
I had high hopes for this bulb based on the previous reviews. I agree that it is an excellent bulb, but "bright white" copy paper still appears slight blue under this light. Better that most 5500K bulbs, but still blue.
In a two bulb fixture, this bulb plus a "soft white" bulb gets pretty darn close to white using the copy paper test.
