Sunmaster
Sunmaster HPS and MH Lamps
Sunmaster covers both ends of the traditional lighting cycle, MH for vegetative growth and HPS for flowering, plus a Retro MH option that's compatible with digital ballasts designed primarily for HPS. If you're running a digital ballast and want to switch between veg and bloom spectrums without buying a second ballast, the Retro MH is built for exactly that switch.
These pair with any compatible digital ballast and a reflector sized to your tent, the JB Bat Wing for wide, even spread or the Deep Bowl for more focused, intense output. Bulb life on HPS and MH lamps does degrade gradually with use even before they fail outright, most growers replace annually or every season to maintain consistent output rather than waiting for visible failure.
Frequently Asked Questions
Can I use a Sunmaster MH lamp in a standard HPS digital ballast?
The Sunmaster Retro MH is specifically designed to work with digital ballasts built for HPS, check your ballast is dual MH/HPS switchable before assuming compatibility with a standard MH lamp.
How often should I replace my HPS or MH bulb?
Most growers replace annually or each season, light output degrades gradually well before the bulb fails completely, so waiting for visible failure means running at reduced output for longer than you realise.
