Anybody tried using Venture "Natural White" lamps?

[Donny Bahama]

From their website:

• Superior color rendering - objects appear as they would outdoors
• Excellent color uniformity and stability over life of lamp due to tipless, formed body arc tube
• Protect merchandise and signage from fading with UV Shield® technology - Blocks nearly all the UV output
• Longer lamp life (20,000+ hours) with 70% survival at rated life
• Don't be left in the dark - 50% faster warm-up time than ceramic or standard metal halide systems
• Hot restart in less than half the time of ceramic metal halide lamps
• Less breakage during shipping and fewer points of failure due to weldless construction of lamps

Almost sounds too good to be true, doesn't it? These are mogul base lamps with a color temp of 5K and a CRI >90. Highest available wattage is 375. Unfortunately, I have no idea how much they cost or where to buy them, but it seems like they'd be worth paying a little more.

Anyone have any knowledge or experience with these?
