The MASTER GreenPower CG T 400W is a high-efficiency HPS grow lamp designed to boost flowering productivity in mid-size cannabis setups. With an output of approximately 56,500 lumens and a 2000K red-orange spectrum, it promotes vigorous bud formation, enhances resin production, and encourages tight, uniform flower development. With a spectral distribution that supports strong photosynthetic activity, it’s ideal for dedicated flower rooms or a supplemental light during late veg and flower. This durable light offers up to 30,000 hours of output for consistent yields across multiple cycles. Its E40 base ensures compatibility with most standard fixtures and 400W ballasts, making it easy to integrate into existing setups. For enhanced durability with the same flowering spectrum, check out the MASTER GreenPower CG T Mogul. If you want more output in the same spectrum, the Philips GreenPower CG T 600W is a powerful upgrade with increased intensity for larger grows.
