PHILIPS 315W CMH AGRO LAMP (930)

Description

PHILIPS 315W CMH AGRO LAMP (930) is the warm-spectrum Ceramic Metal Halide lamp from Philips in the 930 (3000K) specification — the flowering-phase CMH lamp that delivers the orange-red spectral bias of an HPS with the broader spectrum, superior colour rendering, and UV output of ceramic arc tube technology. We have been recommending Philips CMH technology to UK growers since 2017 as the most significant advancement in grow room lighting for producing high-quality, terpene-rich harvests.

The 930 Agro Spectrum and Its Flowering Phase Advantages

The 3000K colour temperature of the Philips 315W CMH Agro 930 places the spectral peak in the warm orange-red region (580–700nm) that drives flowering and fruiting — comparable to HPS in its primary wavelength emphasis. Where the CMH 930 differs fundamentally from HPS is in the breadth of its spectrum and its UV output: the ceramic arc tube maintains a colour rendering index above 90 and produces meaningful UV-A output in the 315–400nm range throughout the lamp’s life. This UV exposure during flowering is the primary driver of elevated terpene and trichome production that growers switching from HPS to CMH consistently report, along with deeper pigmentation in fruiting crops and improved aromatic compound development that defines the quality differential of CMH-grown versus HPS-grown product.

Ballast Compatibility and Setup Requirements

The Philips 315W CMH Agro 930 requires a CMH-specific 315W ballast — standard HPS ballasts cannot drive the CMH ceramic arc tube correctly and will either fail to start the lamp or damage it. Dedicated CMH ballasts from Lumatek, Gavita, and specialist CMH manufacturers all support the 315W specification. Use with a CMH-rated reflector designed for the higher operating temperature of ceramic arc tube lamps. Replace every 20,000 hours or two years for consistent spectral and output performance.

Pair the Philips 315W CMH Agro 930 with a Lumatek 315W CMH ballast and a dedicated CMH reflector for a complete premium flowering system that maximises essential oil and terpene production in every crop.
