36" T5HO Replacement Lamp 6400K

SunBlaster’s 36" T5HO Replacement Lamp in 6400 K is a daylight-spectrum fluorescent tube made for relamping SunBlaster T5HO strip fixtures. The 36-inch (90 cm) lamp draws 39 W and uses a high‑output T5 format to deliver strong vegetative‑stage light while maintaining low heat. The company recommends replacing T5HO lamps after 10,000 hours to keep output near peak. The 6400 K color temperature matches the brand’s “Grow” daylight option and is available alongside other Kelvin options for different stages. This is a bulb‑only SKU; ballasts/fixtures, reflectors, cords and mounting hardware are sold separately. It suits propagation benches, shelf gardens and other narrow runs where a linear source is desired.
