Philips Grow Light Bulbs -- HPS, MH & CMH
Philips is one of the most established grow light bulb manufacturers in commercial horticulture, with a product history spanning decades of greenhouse and indoor production. Their horticultural lighting division (now operating under the Signify brand but still widely sold as Philips GreenPower) produces HPS, metal halide, and CMH bulbs that have been the benchmark for commercial greenhouse lighting output and consistency. For growers running DE HPS or CMH fixtures, Philips bulbs are consistently among the highest-output options available and are backed by the most extensive commercial production data of any horticultural bulb manufacturer.
Philips GreenPower DE HPS Bulbs
Philips GreenPower double-ended HPS lamps are the commercial standard for DE HPS production. The Philips 1000W DE lamp (SON-T AGRO DE and GreenPower DE equivalents) delivers approximately 2,100-2,200 umol/s total output at 2.1+ umol/joule -- among the highest output available in the 1000W DE class. They are the primary replacement bulb recommendation for Gavita, DimLux, and Phantom DE fixtures where photometric output consistency matters for commercial yield targets. Replace Philips DE bulbs every 10,000-12,000 hours to maintain rated output. Browse our 1000W DE HPS fixtures collection for complete DE fixture options alongside replacement Philips bulbs.
Philips CMH Bulbs
Philips MasterColor CDM bulbs (315W and 630W) are the original CMH horticultural lamp and remain the benchmark for CMH bulb quality and consistency. Their ceramic arc tube construction produces the broad, natural-light-like CMH spectrum including UV and far-red components that standard HPS cannot match, at CRI 90+ for accurate plant color assessment. The CDM 315W is the most widely used single-lamp CMH for 3x3 ft canopy coverage; the 630W covers a 4x4 ft footprint. Philips CMH bulbs require a dedicated CMH-compatible ballast -- they are not interchangeable with standard MH or HPS ballasts. Fast shipping.
Philips Grow Light Bulbs FAQ
Are Philips HPS bulbs better than other brands?
Philips GreenPower DE HPS lamps are among the highest-output options in the 1000W DE class and are backed by the most comprehensive commercial photometric data of any HPS bulb manufacturer. For commercial operations where bulb-to-bulb consistency and verified output matter for yield predictability, Philips is a reliable first choice. Ushio and Gavita also produce quality DE HPS bulbs at comparable output levels. For single-ended HPS, the output advantage of DE design is significant regardless of brand -- transitioning from SE to DE HPS typically delivers more improvement than switching between DE brands.
Are Philips CMH bulbs compatible with any CMH ballast?
Philips MasterColor CDM (CMH) bulbs require a ballast specifically designed for CMH lamps -- they are not compatible with standard HPS or MH ballasts. Most CMH fixtures sold by qualified brands (Gavita, Phantom, Iluminar) are sold as complete systems including a CMH-rated ballast designed for the specific Philips CDM lamp configuration. If purchasing bulbs as replacements, confirm the ballast is rated for CMH use and matches the Philips CDM wattage and lamp type specified by the fixture manufacturer. Using an incompatible ballast can damage the lamp or produce significantly reduced output.
