CL RTT 9
T8 LED Retrofit Tube · G13 · 2 ft & 4 ft · 6–18 W · 3000–6000 K
CL RTT 9 is Carden Lighting's T8 LED tube for replacing fluorescent lamps in fixtures that are already installed. It fits the existing G13 lampholder, so the ceiling fixture stays in place and the upgrade happens on site, without swapping equipment or reworking the installation. Available in 2 ft and 4 ft, 6–18 W, 1,200–3,600 lm, 3000–6000 K and a 170° spread. Carden manufactures: wattage and color temperature are set per project within those ranges.

Quantity
- Installs in the fixture already on site; the G13 lamp holder is kept; no need to replace the equipment or work on the ceiling.
- Two standard lengths (2 and 4 ft) that match the most common T8 troffers in offices, schools and stores.
- Color temperature to choose from 3000 to 6000 K; the same model covers warm to cool light, so a whole building is standardized with the same fixture.
- Wattage range from 6 to 18 W to match the light level to the area without changing families.
- 170° diffusion: wide, even coverage typical of the tubular format.
- Minimal construction with the space in operation; the change is made tube by tube, without taking the area out of service.
