See the images I posted showing exactly how they render whites, grays and colors. It was a toss up between the Alzo 45w/150w output 5500K and this Eiko and the Eiko wins for better neutrality based on visual inspection.

Both are way better visually than the 100w 5500K HD Ottlite CFL I bought at Lowes for around $6. The Ottlight renders visually whites and grays a bit bluish green and tends to inject a slight greenish yellow cast to warm pastels like beige and sand, but does well rendering color from digital cameras using AutoWB.

As with other CFL's in general using the Eiko for digital photography doesn't give adequate amount of light unless it's close to the subject as in the image I posted and/or you set up a cluster of at least 12 to get decent shutter speeds to stop movement or having to rely on high ISO settings compared to using a dedicated flash/strobe. IOW two Eiko's will do very well for product shots of small objects as in my posted image whose exposure setting was at 35mm, 1/50's, f/8, ISO 400 for just one bulb 1 1/2 ft. from the subject.

For some reason these lights look VERY bright to the eyes. I mean they REALLY fill a 12x14 ft. room with plenty of light for reading, but digital sensors don't seem to see it that way.

I bought these as an upgrade in lumens for an economy lighting set I had recently purchased for amateur product photography. The set had shipped with Eiko SP30/955K bulbs, but was a little under powered for my needs. I was happy enough with the included bulbs to stick with the Eiko brand. The Eiko SP50/955K bulbs throw out a lot more light, but you would still need a tripod if you're wanting to shoot through umbrellas or soft boxes at f/8, ISO 200 and a two bulb set up.

Be prepared, these bulbs are much larger than household 60 watt equivalent CFL bulbs, but still fit my light stands without the need for any special adapters. I'll upload a size comparison photo to a 12oz. aluminum can.

At the time of purchase, the CRI, color rendering index, was listed as 93 and the lumens 3000. The product box said the CRI is 90+ and the lumens are 2700. No significant electrical hum, but if you are producing video, you may need to investigate further. I don't have any precise way of measuring the color, but Adobe Camera Raw balances a gray card to 5650 Kelvin and +33 magenta. I'm happy with the product and would buy them again, which should be in about 10,000 hours?

I bought 2 of these lights to brighten up my garage. They do the job but are tricky to install because they are so big. You need a ladder, the pole/holders they sell to install light bulbs in high places don't work with these.
