48" T5HO Replacement 6400K

SunBlaster’s 48" T5HO Replacement Lamp 6400K is a 54 W high-output fluorescent tube designed to re-lamp SunBlaster T5HO strip light fixtures. The 6400 K daylight spectrum supports propagation and vegetative growth, with spectral peaks near 435 nm (blue) and 615 nm (red). The 48-inch model is rated for 10,000 hours and is intended to be positioned close to the canopy; SunBlaster advises placing T5HO lighting approximately 6–8 inches above plants for best response. Typical single-lamp footprint is about 1 ft x 4 ft (≈120 x 30 cm) when used as a propagation light. This lamp is a direct replacement for the 4 ft SunBlaster T5HO fixtures and maintains the same output and spectrum as supplied with the original combo and kit versions.
