The Skylighter actually appears whiter than 6500K Daylight and popular 5500K full spectrum lamps.
"I had been talked into using 7500K (C75) lamps in my paint studio. Despite claims of having the best ability to render true color, reds are dull. How is your 6800K lamp different?"
The Skylighter is rich in phosphors in both the blue and red end of the spectrum, a unique feature which renders the whole spectrum with equal richness.
Why is The Skylighter more expensive? Why can't I just get some 5.00 full spectrum tubes at a home center?
Commen full spectrum lamps are made with a mix of three phosphors. The seven phosphor blend of The Skylighter (TM) produces a truer light, and has a unique spike of scotopic energy which makes the lamp appear brighter which marketly improves visual acuity beyond the ability of a full spectrum lamp.

"What's the skinny on 'long life' fluorescent lamps?"
This depends whether we discuss total life or useful life.
The total life ends when the lamp goes dark altogether. This occurs when the electron-emitting coating on the cathode is used up. Adding extra coating permits extra overall hours.
The useful life ends when the gasses and phosphors degrade and the lamp no longer operates within design specifications.
After two or three years the color temperature, CRI, and brightness degrade to where the lamp does little more than keep you out of the dark. This is true with ALL general purpose fluorescent lamps, long life or not.
"What's with fixtures that need to be blinked off and on to start?"
Try touching the glass tube, if the lamp "pops on", it's probably a grounding issue. Tubes which are worn, dirty, cold, or have poor socket seating often hesitate.
"How 'black' should the ends of a lamp be allowed to get before it's time to change the bulb?"
Again, lamps should be replaced every two to three years regardless of end blackening. Moderate blackening is a normal part of a lamp's life cycle. Dense blackness on an end is a sign the lamp should be replaced right away to avoid ballast damage. If dense blackening is seen on both ends of a tube, the ballast may already be bad.
"Are there applications where The Skylighter might not be the best choice?"
Of course. Every application is unique. In such a situation we'd be happy to steer you in the right direction.
