The sign industry has struggled for a long time to find a retrofit LED solution for single and double sided outdoor signs that presently are using conventional T12 HO fluorescent tubes. This tube has arrived. Specifically designed as a direct and easy replacement for T8-T12 HO fluorescent tubes, it is the only LED sign tube that is IP65 rated with a clear plastic tube encasing the light end to end so no moisture gets inside. The LED strips feature proprietary, specially designed lenses that cover each individual LED chip enhancing the light output while also projecting an even light field without any hot spots. Designed as 180ᵒ or as 360ᵒ for single or double sided sign applications. For ease of installation the LED sign tubes are fitted with rotatable RD17 HO end caps so they can be easily rotated into the perfect position for maximum light output and an even light field. Bulb Daddy's LED retrofit sign tubes come in lengths of 4Ft, 5Ft, 6Ft, and 8Ft including the most sought after F48 T8HO and are available in 20W to 48W depending on the length and projection beam angle.
