you want a really well lit room. There are formulas out there that you can find that show how many lumens you need for your space (based on square footage), and taking into account what type of room it is.
One of the most basic specs—and most important measurements—for any projector is lumens. Quite simply, how many lumens the projector delivers determines the range of usable image sizes for any given level of ambient light. Go larger than the high end of the range, and colors will become i...
A theater projector probably emits more total light (measured in lumens) than any smartphone, but the phone packs more light into a smaller space. That’s why using a phone during a movie is so taboo: with at least ten times the candela per square meter than the screen, it’s basically...
Switching tolinear high baysfrom T5 Linear High Bays is a smart and simple process. These powerful options can offer light levels that are not obtainable with T5 tube lighting fixtures. Here, we are talking about 71,000 lumens. To offer such a light, you require 18 tubes if you are using...

Per watt, LEDs output more lumens (or quantities of visible light) than regular incandescent bulbs. Light emitting diodes have a higher luminous efficacy (how efficiently electricity is converted to visible light) than incandescents – a 60-watt incandescent bulb can generate between 750-900 lumens...
