Let’s recap how to gauge how much light you need for a space. Multiply your room square footage by the footcandle requirement. For example, a 100-square foot living room, which needs 20 foot candles, will need
For example, a 100-watt equivalent LED bulb may produce around 1600-1800 lumens. When selecting an LED bulb, it’s important to consider the desired level of brightness for your space. Depending on the room and lighting needs, you may opt for a bulb with a higher or lower lumen output....
For example, if you have a fluorescent poster and shine a black light on it in a dark room, the poster will glow brightly. You may have also seen pieces of paper that look blank in regular light but spell out a glowing message under a black light. Many amusement parks use hand...
It could take a team of programmers more than a year to duplicate a real room accurately in virtual space. Another challenge for VE system developers is creating a system that avoids bad ergonomics. Many systems rely on hardware that encumbers a user or limits his options through physical ...
Given how critical this spec is to choosing the right projector for the image size you want, it can be helpful to know a little more about it. This is especially true because there are several ways to measure lumens, so two projectors with the same lumen rating aren't necessarily equally...

projector and the screen or wall. Moving the projector closer to the screen or wall will result in a smaller image, while moving it farther away will make the image larger. Additionally, many projectors have zoom controls that allow you to adjust the image size without physically moving the ...
According to that model, light waves come in many sizes. The size of a wave is measured as its wavelength, which is the distance between any two corresponding points on successive waves, usually peak to peak or trough to trough. The wavelengths of the light we can see range from 400 to...
