    Converting 25 8'x2 fluorescents to LED - 30' ceiling warehouse

    Hi. My first job with fluorescent LED replacement. This is for a large t-shirt printing facility. 30' ceilings.

    Any recommendations/experience with brands to use? website? lumens & color temperature?

    I plan to keep existing fixtures and use LED lamps, by-passing ballast.

    Thanks

    Keystone is a popular brand. 4000K minimum, 5000 is even better IMO.

    Be sure and rent a scissor lift.

    I agree 100% about taking the ballasts out of the circuit!

    I only have a little experience with this. Each time I had to replace the tombstones on the feed side of the LED tube with different non-shunted tombstones. The first time I did not expect this and switched on to a bolted fault. I also did this first replacement in my own shop...

    The newer tubes that I use can be wired either on one end or both. ie; same end- one pin hot the other neutral
    different ends - hot on one end, neutral on the other. Shunted sockets won't matter on the different end wiring.

    OP said 8' fixtures, which likely means single pin tombstones.

    I did miss that. Definitely bypass those ballasts!

    Now why do you have to mess everything up by bringing up the facts?
