When I turn on a light, the glow ring flashes orange and the light turns off or dims.
The maximum load the Lightpad can handle is 400 watts for incandescent bulbs and 150 for LED & CFL.
If you connect the Lightpad to a load that is greater than 400W, the Lightpad will self-limit itself to 400W. The results of this limiting are different depending on whether you have the Lighpad set up as a dimmer vs a switch.
If the Lightpad is set up as a switch, the light will turn off if the max load exceeds 400 watts. The glow ring will also flash orange as this happens.
If the Lightpad is set up as a dimmer, the lights will dim to a level below 400 watts. The glow ring will flash orange the first time this happens, but thereafter, the Lightpad is smart enough to know to not increase the light level on that load above 400W.
To eliminate this issue, try reducing the load by using bulbs with a lower rating. If you are using Incandescent bulbs try switching to LED or CFL.
If the Lightpad has been derated by removing the metal fins on the side and you are using Incandescent bulbs, then you should reduce the max load by 50 watts per side removed.
One side removed = 350 watts max load.
Both sides removed = 300 watts max load.
LED and CFL bulbs do not require a reducing the max load and remains the same 150 watts.
In all cases, the Lightpad has secondary protection in the form of temperature sensors. Each lightpad has several temperature sensors and if the load is too high for the Lightpad to safely dissipate, and temperatures climb too high, the Lightpad will turn itself off until the temperature decreases to a safe level.
