Tubes are available from any and all LED suppliers. Our high quality tubes have a very low failure rate (less than 5 out of a 1,000) and do not require socket change outs. We have tubes in 2ft, 3ft, and, of course, 4ft lengths. We are now also stocking 8′ F96 T12 replacement LED tubes in single pin end or HO (R17D) end. Whether you need 1 or 10,000 pieces, we can fulfill your order.
