T8 hybrid LED tube replacement tested
The I found out that Lowes had utilitech 2,000lumen 18w single pack hybrid T8 LEDs on clearance for $4 each.
So I got some to replace my aging 35w and 40w T8 tubes.
Stated off by just plugging the T8 into the ballast powered fixture. That reduced consumption from 35w to 21 watts. Not bad.
Next I unwired the ballast and tried powering them up straight from 120v power.
That dropped consumption to 17 watts per tube.
So, on regular T8 tubes my 6 light T8 fixture used 2.1 amps, then on 120v powered LED it dropped to 0.85 amps.
Also the LEDs are brighter than what they replaced.
