The LUMii 300W EnviroGro Super Cool CFL Lamp (14,000K) emits a crisp, ultra-white spectrum that parallels a clear-blue sky. Despite its substantial 300-watt output, its integrated ballast allows for plug-and-play use with standard E40 CFL reflectors, while generating much less heat than comparable HID bulbs. At approximately 380 mm long, 160 mm in diameter, and weighing around 1.25 kg, this robust lamp is both compact and durable. Its super-cool blue-white output promotes dense foliage, short internodal spacing, and robust root systems, helping growers maintain strong, compact plant structure in the vegetative phase. Ideal for use in propagation racks, compact tents, or any grow environment where heat dispersion and energy efficiency are priorities, the 300W Super Cool CFL reduces electricity costs while delivering reliable illumination for early plant cycles. LUMii’s product line is quite extensive and they have something to fit all types of gardens. So don’t hesitate to check out their LUMii Black 720W or LUMii Sunblaster 600W.
