No, we're not talking about that green color media your lighting professor warned you about…
We're talking about plenty of light from lower wattage lamps to do the job.
ETC's Source Four has always been green. What do we mean?
Efficiency is a rating of how many lamp lumens actually make it out of the front of the fixture as usable light. (Field Lumens/Lamp Lumens = Efficiency)
Lumens per watt is a very important measurement in these days of growing regulation of lighting based on ecological concerns.
In 1992, we introduced the Source Four - a fixture that revolutionized the lighting world with its efficiency and efficacy. Today those numbers mean more than ever. Efficiency and efficacy mean great lighting with less impact on our world.
At ETC, it's easy being green.
