NEW 4ft LED TUBES - liquidating at $6 (or less?)
We got very lucky at an auction and picked up a container load of LED tubes, used to retrofit fluorescent lights. These things are fantastic. They only use 15W of power, as compared to 18W for most LEDs or 40W for many fluorescent tubes.
The tubes will pay for themselves, because of electricity savings, in just a year. 25 watts saved x $0.28 saved per watt per year = $7 saved in just one year. (Assumed usage is approximate "office hours.")
You need to bypass the ballast when installing these; that is an easy process I could walk you through.
We have over 20,000 of these! We re-lamped our offices and warehouse with LEDs last year, and could not be happier. The light is brighter, and we haven't had to replace a single ballast or tube since (and won't, for 21 more years.)
Here is an Amazon listing of these exact LED tubes: https://www.amazon.com/Zenaro-RSLT81-4FT-15W-5000-ND-IDS-CL-LED-Tube-Lighting/dp/B00A3Z6Z5Q
Note that Amazon wants $32 for them. (The $10 listing is ours.)
Minimum quantity is a case of 12. Better pricing on pallets, which are 49 cases. The lamps are in our warehouse in Matthews.
Holler with any questions!
