Growers Choice 630W DE CMH 3K-R: Red-Enhanced Bloom Conversion Lamp
The Growers Choice 630W DE CMH 3K-R is the industry's first double-ended CMH/LEC conversion lamp — it drops into any existing DE fixture and converts it to CMH spectral quality without swapping ballasts, hoods, or reflectors. The 3000K Red spectrum delivers enhanced red intensity with a taller far-red peak and added UV output compared to standard CMH lamps, targeting the metabolic pathways that drive flower density, tighter internodes, and secondary metabolite expression during bloom.
CMH/LEC Conversion for Existing Double-Ended Fixture Platforms
The conversion angle is what makes this lamp unique in the market. Facilities that already run DE HPS fixtures can slot this in and gain CMH spectral quality — fuller spectrum, better CRI, more UV — without the capital expense of new fixture platforms. The slightly higher PAR output compared to standard 630W CMH lamps translates to improved flower density and yield potential, while the refined 3K-R spectrum supports vigorous flowering with the kind of resin production that craft growers and commercial rooms targeting premium quality are looking for. Compatible with indoor, greenhouse, and hydroponic lighting setups running standard DE fixture infrastructure.
Key Features
- DE CMH/LEC Conversion: Converts any existing double-ended fixture to CMH spectral quality without new ballasts, hoods, or reflectors — just swap the lamp
- 3000K Red Enhanced Spectrum: Tuned with added UV and a taller far-red peak to stimulate metabolic activity, resin production, and flower density during bloom
- Higher PAR Than Standard 630W CMH: Delivers slightly more photosynthetically active radiation than conventional CMH lamps for improved yield potential per fixture
- UV Output for Secondary Metabolites: UV spectral component supports the metabolic pathways that drive terpene and resin expression in flowering applications
- Standard DE Fixture Compatible: Fits any double-ended fixture platform, making it a drop-in upgrade path from HPS to CMH without infrastructure changes
