NextLight LED grow lights use a full-spectrum white light that mimics natural sunlight. They have a light output similar to an HPS bulb, but with much more blue light, making them highly effective during all grow cycles.
The NextLight 420H is a high-efficiency-bright white LED grow light that is designed for growers who want to maximize yield in a limited space. The NextLight 420H is the most powerful fixture in the NextLight household series. This household series is specially designed for experienced and novice family growers.

The NextLight 420H has the power and versatility of all stages of plant growth. The onboard dimmer allows you to dial in the dimming value between 0-100%, allowing you to precisely control the required light intensity. The NextLight 420H is ideal for 3'x 3'flower footprint and 5'x 5'vegetable footprint.
