Maxibright Daylight Compact 315W CMH Ballast

Maxibright Daylight Compact 315W CMH Ballast — Magnetic Variant

The compact magnetic version of Maxibright's 315W CMH ballast — same proven power technology as the Digital Daylight ballast, in a more cost-effective package for larger-scale growers. Compatible with all 315W CMH and CDM lamps across brands.

Why growers choose the Daylight Compact 315W Ballast:

• Same power and technology as Digital version — drives 315W CMH lamps correctly with low-frequency square-wave output
• Compact magnetic construction — cost-effective for larger multi-light setups where Digital pricing adds up
• Compatible with any 315W CMH/CDM lamp — not brand-locked, works with Philips, LUMii, Maxibright
• Lower cost per unit — ideal for growers running multiple fixtures where saving per-ballast matters
• Reliable magnetic ballast design — fewer electronic components, fewer failure points over time
• Maxibright support and warranty — proper UK manufacturer backing

Who it's not for:

Magnetic ballasts are slightly less efficient than Digital versions and run warmer — if you want the latest efficiency and silent running, the Daylight Digital 315W Ballast is the upgrade. Not compatible with HPS lamps — CMH only. Always fit a CMH lamp to a CMH-rated ballast; never to a standard HPS ballast.
