The Cultilite T8 Cloning Tube 25W is a dedicated LED tube for cloning, germination, and early propagation. It uses Samsung 2835 LEDs in a cool white 6500K spectrum with a blue-leaning peak (440–460 nm) to encourage compact rooting. Rated at 25 W (±5%), the tube delivers a PPF of 60 µmol/s with an efficacy of 2.4 µmol/J. Recommended coverage is 4×1 ft when mounted about 20 cm above the canopy. The 1250 mm T8 form factor with a PC + aluminum body supports heat dissipation and durability; protection is IP44 with a claimed lifetime over 30,000 hours. This model is intended for close, uniform lighting over cloning trays and shelves rather than full-vegetative growth.
