The technology involved has potential for many other applications besides light bulbs, Soljačić says. The same approach could “have dramatic implications” for the performance of energy-conversion schemes such as thermo-photovoltaics. In a thermo-photovoltaic device, heat from an external source (chemical, solar, etc.) makes a material glow, causing it to emit light that is converted into electricity by a photovoltaic absorber.

I don't know how much faith I would put in a website that is trying to sell me a software app to counter blue wavelength light since that filtering is available for free on my phone and computer. I have been using the full spectrum "daylight" LED at home. I like their more balanced colours can't quantify any difference for me.S Haze wrote:Since this experiment began I think the understanding of how artificial light and its parameters like wavelength and flicker rate affect us has come a long way! The image is one I've seen before and sums up why CFLS especially might be not-so-good for us as biological organisms. The webpage I pulled it from seems fairly comprehensive and legit too.
