SunBlaster T5HO Replacement Lamp

The SunBlaster T5HO Replacement Lamp is designed to restore strong, reliable light output in compatible SunBlaster T5HO fixtures, strip lights and grow light combos. Available in 6400K and 2700K spectrum options, this high-output replacement lamp allows growers to choose the right light colour for different stages of plant growth.

The 6400K lamp provides a cool daylight-style spectrum that is ideal for propagation, seedlings, cuttings, clones, herbs, leafy greens, microgreens and vegetative growth.
