Does the WattManager® work well with incandescent or other lamps ?
The WattManager® technology is specially designed for gas discharge lamps (HID, Fluorescent) and it works efficiently by saving electrical power of up to 35% without substantial lumen loss. These types of lamps require less power to maintain the arc than to ignite the arc. The incandescent have a different physic of operation. Light is generated by thermionic emission at the filament. In cold condition, the filament of incandescent lamps has an extremely low ohmic resistance. Due to this, switch-on peaks of up to 16 times lamp operating current can occur. The more power reduced, the more is the lumen loss. Therefore, the power saving versus the light output is not an advantage.
