| | SPD technology is a revolutionary technology in that it offers many important benefits. For example, SPD's or "light valves," use either a liquid suspension or a film within which droplets of liquid suspension are distributed. : - Operate off of ordinary AC voltage or battery power.
- Require very little power (less than 0.06 watts per square foot).
- Change tint almost instantly (1-2 seconds for complete change).
- Change tint uniformly over the entire surface area, regardless of size.
- Are adjustable over a wide range of light transmission levels.
- Operate over a very wide temperature range.
- Are highly durable (successfully tested at millions of on/off cycles).
- Can be bent or rolled.
