Hi there,

Does anyone have a solution for these lightleaks caused by kingbrite QB’s?

I’ve tried different timers but the problems persists.

thank you

Check the outlet, and any outlets upstream from your outlet. You might find that the hot and neutral are reversed on the wiring. This gave me the EXACT same problem with timers. As soon as I swapped the neutral and hot to their correct terminals on the outlet..boom all the timers I bought worked (it was with a different light but same issue)

If the light when not plugged in through a timer goes off totally when switched, and no timers worked for you and it is always a small amount of light I would put some money on that being the issue. Keep in mind with wiring if there are 5 outlets connected to the circuit and one upstream has the neutral and hot reversed and the others are wired correctly, this would still cause the same issue.

The issue seems to be caused because of single pole switching mechanisms in most timers.

Light Timer Woes (Power Leak when off) LED light

I am frustrated. I have ordered now two different light timers, an analog BN-LINK timer, and an ETEKCITY outdoor smart wifi controlled switched double outlet. First I tried the BN-LINK analog, sure the timer works but it leaks voltage, enough for the LEDs to be extremely lowly lit..I mean we...

Okay, with outlet you mean the outlet of the driver? Or the outlet from the wall?

The wall outlet. Nothing to do with your light or the timer. The wiring in the hosue.

You would need to turn off the breaker to inspect the outlet, and if the hot and neutral aren't reversed there you would need to see what other outlets are on that circuit. Pretty simply though if you can plug straight into the wall (without a timer) and turn off the light and it goes completely off, but when using a timer you have a light leak..I looked everywhere for the cause of this and the ONLY cause I could find was the hot and neutral being reversed.

Ahh I see, thanks for explaining. The problem is that these lights dont have an off switch so I can’t check the hypothesis as you proposed.

Someone else had a issue, was just a aged plug in, earth ground or something, I would try replacing the plug as well if going in for a look for shits and giggles.

I recently replaced the plug to meet requirments for the medicinal permit. But I’ll look into that aswell.
