Grow Light Reflectors

Grow light reflectors direct and distribute light from HID lamps more efficiently across the canopy, reducing hotspots and improving uniformity. Choosing the right reflector can significantly increase the proportion of lamp output that reaches your plants.We currently stock three reflector products. The E40 to CDM Adapter converts a standard E40 HID fitting to accept CMH/CDM lamps. The Coolshade 150mm is a ducted cooled reflector for removing heat directly from the lamp zone. The Lumatek Shinobi 80cm White Reflector is a wide-coverage, highly reflective commercial-grade unit compatible with standard HID lamps.
