[Shop-talk] led tubes and short memory

[Donald H Locker]

Hop on over to the https://www.jesled.com site; they have more info than
amazon (and may have better prices; depends) to guide you. If their
specifications are not sufficiently clear, it might be worth looking at
other manufacturers' products. LED tubes are becoming much more common.

One other site I looked at was https://www.viribright.com/
