Regarding SLIders - I know that I also have this problem, and here is what I've worked out about it...

Visible Light (and also INvisible light) are just slight deviations along the Intensity Path of Energy Waves. All of the currently operating Steetlamps that I have seen now operate on a small sensor located near the top of the unit - that sensor is there to detect light. Its a Negative-Switch, whereby the unit is OFF when there is more than X-amount of light impacting the sensor, and ON when the light impacting the sensor drops below a given value.

Everyone casts light-energy in the spectrum beyond visible light, the amount of light-energy you cast corresponds to your vibrational frequency, which will increase and decrease, oscillating up and down throughout the day based on your emotional purity. The more PURE the emotion is, the more Light-Energy will be cast by your body. How does that work when our emotions are a tapesty of differences themselves? Energy itself is also a tapestry of differences. they are mutually compatible.

At least, that's what is going on from how my mind has pieced together the puzzle
