Got the fixtures bulbs in.
So the CNSUNWAY Bulbs did not match their label claims at all, supposed to pull near 22 watts I was only seeing 15.5 Watts(30% less), they also tout those bulbs a " 100-110lm per watt " So that's looking like 1630 Lumen not 2400. Also to note these bulbs are aluminum and plastic construction. I reached out to the manufacture and they just said to return them for my money back. I got them on amazon so was not worried.
So I went and purchased https://www.1000bulbs.com/fil/products/211953 "TCP-10195B 4 ft. LED T8 Tube - 2400 Lumens - Ballast Bypass - 5000K " which with shipping are a little more expensive but, these bulbs are rated at 130 lm per watt.
I also had to buy non-shunted tombstones as the Thomas fixtures came with shunted ones(which worked with the CNSUNWAY bulbs).
I got the TCP bulbs in and they are completely made from glass with plastic end caps. The LED strip is mounted on the back side of the glass tube.
I tested the TCP bulbs and they pull 16.4 watts which is 11% down on label claims but, at 130 lumens per watt that should be 2132 Lumens.
Crudely using a lumen App on my phone in the same position and angle, I was measuring 30-40% more Foot Candles with the TCP bulbs which is inline with the power draw and specs.
As for color temperature the TCP bulbs are every so slightly less blue but, either bulb is fine in that department.
