Interlux T5 Bloom Bulb - 4 ft - 3000K - 54W

Warm Red-Rich Light for Flowering - 4 ft T5 Tube

Plants moving from vegetative growth into flowering respond to a different light mix than they did earlier. This Interlux T5 bloom bulb gives a warm 3000K output with a red-rich spectrum, so you can match your lighting to the flowering stage without changing your whole setup.

Sold as a single 4 ft bulb, it suits growers who want to replace one tube, trial a bloom spectrum in one fixture, or stock spares. Growers running many fixtures can order several to relamp a full room.
