Innovative new lighting

[begreen]

An artificial skylight that is virtually indistinguishable from natural sunlight. This makes underground lighting much more attractive.

Are these available in the states?

I think they are just being introduced commercially in Europe at this point.

I'd still want to put my lux meter on them. The OP tech is spiffy....I'll be impressed after I see the price and running costs. Can achieve similar effects with off the shelf tech now, no nanoparticles required.

I love my house, but the builder (in 1960, RIP) obviously did not know where the sun is in the sky. Built all these picture windows on the North facing living room and a giant stonework planter in the North sided main entrance (with no window at all). I got 60W of LED spots and put them 10' above the planter and folks who don't think about it figure there must be skylight shining on the planter. Eats about 300kWh/year. The liv room got tube skylights that use 0 kWh/yr.

All better.

The tube lights are great. I installed one for an interior bathroom and another in the back entryway which has no windows. Bright light most days, 0 kwh.

Tube skylights are great but not always an option. Otherwise there would be one in our kitchen. For a dramatic change in interior lighting with no sunlight access these could be great. And they work at night and on cloudy days.
