24" T5HO Replacement Lamp 6400K

SunBlaster’s 24-inch T5HO Replacement Lamp 6400K is the direct replacement tube for SunBlaster T5HO strip fixtures and combo kits. The 6400K full-spectrum phosphor is intended for propagation and vegetative growth. Nominal power is 24 W, and SunBlaster recommends replacing after roughly 10,000 operating hours to maintain output. The 24-inch format is commonly used over a standard 1020 propagation tray when paired with SunBlaster’s NanoDome or 24-inch T5HO fixture, providing even coverage at a 6–8 inch hanging height. This lamp corresponds to SunBlaster item code 0900175 as listed on the brand’s replacement-lamp lineup. Use anywhere a 24-inch high-output T5 fluorescent (G5) tube is specified within a SunBlaster T5HO system for seedlings, cuttings, microgreens, and leafy herbs.
