GrowLite 315W DE CMH: 95% Solar Spectrum Replication for Full-Cycle Growth

The GrowLite 315W DE CMH replicates 95% of the full solar spectrum, producing a light profile closer to natural sunlight than standard MH or HPS lamps can achieve. With 28,500 initial lumens from a 315W double-ended ceramic metal halide arc tube, the lamp delivers the spectral breadth needed for healthy growth across all plant stages — from vegetative structure building through flowering and fruit set. The full-spectrum output at approximately 4000K means plants receive balanced blue, red, and far-red wavelengths rather than the narrow spectral bands that single-phosphor lamps rely on.

20,000-Hour DE CMH Lamp for Commercial and Craft Growing Operations

Rated at 20,000 hours, the GrowLite 315W outlasts most competing CMH lamps by a significant margin, reducing replacement frequency and per-cycle lamp costs for operations running large fixture counts. The double-ended format provides more uniform light distribution and lower lumen depreciation than single-ended CMH designs. This lamp pairs with DE 315W CMH fixtures and ballasts — note that short-wave ultraviolet radiation is present, so protective eyewear is essential when working near the lamp. The GrowLite 315W is a strong option for growers who want one lamp spectrum covering both veg and bloom without switching between Kelvin-specific bulbs each cycle.

Key Features

  • 95% Solar Spectrum Replication: Delivers a spectral profile that closely matches natural sunlight, providing balanced wavelengths for complete photomorphogenic responses across all growth stages
  • 28,500 Initial Lumens: Strong lumen output from a 315W DE platform that provides the light intensity needed for dense canopy penetration and full-cycle growing
  • 4000K Full-Spectrum Output: Balanced color temperature covers blue vegetative wavelengths and red flowering wavelengths in a single lamp, eliminating the need for Kelvin-specific swaps
  • 20,000-Hour Rated Life: Outlasts most CMH lamps on the market, reducing replacement costs and maintenance downtime for commercial and craft operations
  • Double-Ended Configuration: DE format provides more uniform light distribution and lower lumen depreciation over the lamp's service life compared to SE designs
