Found these definitions of light terms

I came across these definitions that even I was able to understand. I hope they're accurate and helpful to other non-tech Flashaholics

Ah, the power of the internet. Good find.

I think I found some errors:

"Dielectric Coatings - are microscopic layers of clear materials which alter the transmission and reflection of light through clear glass. These coatings are used on the reflectors of SoLux bulbs."

I thought those were "dichroic" coatings. A dielectric is an electrical insulator.

Also, their definition of candelas is a little suspect, but I can't put my finger on it:

"Candle Power (Candelas) - Used by lighting designers to calculate the foot-candles illuminating a surface (C.P./distance in feet squared) or Lux illuminating a surface (C.P./distance in meters squared)"

I e-mailed Solux and got the following:

FYI: the substance used to make thin film coatings to reflect various wavelengths of light are made up of dielectric material, hence the term "dielectric coatings"... I would refer you to any "Opitcal Thin Films"
textbook.
