The BP4000 by Bestva is a high-output LED grow light ideal for growers running large-scale setups. Pulling 400 watts with an efficiency rating up to 2.7 μmol/J, it delivers intense, full-spectrum light that supports both vegetative and flowering stages. Equipped with Samsung LM301B diodes and enhanced 660 nm reds, it provides lush growth, deep canopy penetration, and dense, resinous buds. Its large design ensures even light distribution with no hot spots, while the fanless, aluminum board offers passive cooling for quiet operation. The built-in dimmer gives you control of light intensity throughout the grow cycle — meaning you can fine-tune illumination based on the unique needs of your grow —- making it a great choice for growers who need pro-level results in tents or open-room setups. If you’re exploring high-output options for your next grow, check out the Double Chips 4000W. For an even more advanced alternative, the Pro 4000W is where it’s at.
