Maxibright 315W Horizon Remote CDM Lighting Kit – CMH

Wide-angle CMH light that fills the whole canopy, not just the middle

The 315W Horizon Remote CDM Lighting Kit pairs the Maxibright Horizon Remote wide-angle reflector with a remote 315W Maxibright Daylight CDM ballast and a Philips 315W CDM lamp (Elite 942 or 930 Agro) to throw light outward across the canopy instead of piling it directly under the fixture. That wide spread mimics natural daylight and solves the classic problem of bright tops and shaded, underlit lower growth. The remote ballast sits outside the tent to keep heat away from the plants, and the broad ceramic metal halide spectrum carries genuine UVA and UVB for stronger structure and denser flowers.

What's Included

• Maxibright Daylight 315W CDM ballast (remote design)
• Maxibright Horizon Remote wide-angle reflector
• Philips 315W CDM lamp: Elite 942 (4200K) or 930 Agro (3100K)
• Connection leads

Key Benefits

• Wide-angle Horizon reflector spreads light evenly across the canopy and hits plants from multiple angles
• Full CMH spectrum with UVA and UVB for healthier development, better resin and denser flower
• Elite 942 Veg 4200K lamp drives vigorous, compact vegetative growth with high 92 CRI colour rendering
• Remote ballast design moves heat outside the tent, protecting canopy temperature and lamp stability
• 1.2m x 1.2m coverage at 400mm makes it ideal as standalone light or supplemental fill between HPS fixtures
• Works across hydroponics, coco and soil in grow tents and grow rooms

Underlit lower growth and stretched plants?

Most indoor setups suffer from uneven canopy lighting where top leaves grab the light and lower branches sit in shade, causing excessive stretch and weak flowering underneath. The Horizon reflector fixes this by casting light over a wider area and from side angles, encouraging a fuller structure with more flowering sites, while the added UVA and UVB support tighter internodes and improved flower density.

How to Use

1. Fit the 315W CDM lamp securely into the Horizon reflector socket.
2. Hang the reflector above the canopy using adjustable hangers.
3. Place the Maxibright Daylight ballast outside the tent or grow room where possible to reduce heat.
4. Connect the reflector to the ballast with the supplied leads and plug into a suitable supply.
5. On first use, run the lamp continuously for at least 15 minutes so the internal metals fuse correctly.
6. Position the reflector roughly 400mm above the canopy and raise it as plants grow.
