CFL Lights

CFL and T5 fluorescent grow lights deliver a broad, cool-white spectrum with very low heat output, making them the preferred choice for propagation, seedling development and early vegetative growth.We currently stock the T5 54W Blue Sylvania — a 54-watt blue-spectrum fluorescent tube optimised for vegetative growth and propagation. The 6500K blue spectrum encourages compact, healthy leaf development in young plants and cuttings. T5 tubes run cool enough to position close to delicate plant material without heat stress.For higher-output lighting, browse our full Grow Lights range.
