The Sunblaster 48" T5HO 2700K Replacement Lamp is a 54 watt, 4 foot high-output fluorescent grow light bulb designed with a warm 2700K colour spectrum specifically for the flowering and fruiting stages of plant growth.
-
Length: 48 inches (4 feet)
-
Power Output: 54 Watts
-
Color Temperature: 2700 Kelvin (warm, red/orange-toned light)
-
Lifespan: Rated for approximately 10,000 hours of operation before needing replacement to maintain peak photosynthetic output.
-
Compatibility: Drops directly into standard 48-inch T5HO (High Output) lighting fixtures and strip lights without requiring extra hardware or rewiring.
-
Flowering & Fruiting: While cool spectrum lamps (like 6400K) are used for seedlings, clones, and leafy vegetative growth, the warm 2700K spectrum mimics late-season natural light to encourage plants to bloom, flower, and produce fruit.
-
Low Heat: Like other Sunblaster T5HO Replacement Lamp, this bulb runs cool enough to be placed close (6 to 8 inches) to plant canopies without burning them, maximizing light absorption.
