Colour rendering from LED lighting
A horseshoe in a furnace gets red-hot, then white-hot as yellow green and blue get added to the red in its spectrum. At low temperature it has only long wavelengths, to which decreasingly short wavelengths are added as its temperature rises. Black-body radiation is the electromagnetic radiation that is emitted by a perfectly non-reflective object - hence 'black' - at any particular temperature. Daylight is not quite sunlight, but a mixture of slightly yellow-ish sunlight and the blue of the sky, said Nobbs. Three have overlapping sensitivity bands centred on red green and blue. The fourth is for night vision and plays no part in colour vision. Humans do not have constant colour sensitivity across this band.

Lamp HPS FAQ
Where can I find a cheap grow light? Do you need a special lamp for a 400- 600w hps bulb, or can u use a reg 1?Is there an online store where I could purchase a lamp specifically for a HPS bulb cheap? They seem to be $85.00 + and I think it's ridiculous.
Is there ghetto way to grow plants indoors? Thanks. I use 4 foot florescent fixtures with Grow-Lux bulbs. I got them from Home Depot. Works great and it's cheap. My bulbs have lasted 8 years now. Hope this helps.
