LED Grow Light for Indoor Plants, TSW 2000 300W Full Spectrum Panel with Dimming for Seed to Flower Growth

This LED grow light brings adjustable, full-spectrum lighting to indoor plants from seed to flower. The Mars Hydro TSW 2000 draws 300W and provides a 4 × 4 ft vegetative coverage area or a 3 × 3 ft flowering area, helping you plan lighting around the stage of your grow.

An independent dimming knob on the removable driver lets you adjust brightness from 0–100% as plants develop. The reflective hood helps direct light toward the growing area, while passive cooling supports a setup without active fan cooling. A power cord, wire hangers and ratchet hangers are included for hanging the panel.

Use the panel in grow tents, small grow rooms, cabinets, closets or plant shelves. Optional Bluetooth brightness control through the MarsPro app requires the separately purchased iConnectu accessory; it is not included with the light.
