Growers Choice DE 600W MH 10K: UV-B Finishing Lamp for Maximum Resin Production
The Growers Choice DE 600W MH 10K is a dedicated finishing lamp built to run during the last 7–14 days of flowering, where its 10,000K color temperature and strong UV-B peaks trigger a defensive resin response in plants. UV-B light causes plants to produce their own form of sunscreen — a dense layer of trichomes and essential oils — which translates directly to increased resin weight at harvest. The 650 µmol/s photon flux from a 600W draw provides enough intensity to drive that UV response without overwhelming the canopy with excess heat.
Double-Ended Quartz Glass Construction for 25+ Flowering Cycles
Rated at 6,000 hours with only 5% degradation at 10,000 hours, the lamp holds its spectral output and UV intensity deep into its service life — growers report getting 25+ flowering cycles from a single lamp before replacement is needed. The quartz glass arc tube maintains consistent spectral output and PAR production cycle after cycle. At 36,000 lumens and CRI 90, the 10K delivers a broad spectral profile with the specific UV peaks that make finishing lamps effective. Horizontal burning position (HOR ±15°) fits standard 600W DE fixtures. Always wear protective lenses when operating near this lamp.
Key Features
- UV-B Enhanced Resin Production: Strong ultraviolet peaks trigger a defensive trichome response in plants, increasing resin density and essential oil weight during the final days of flowering
- 650 µmol/s Photon Flux: Delivers targeted finishing intensity from a 600W draw without the excess heat that higher-wattage lamps push into the canopy during late bloom
- 10,000K Finishing Spectrum: Ultra-cool color temperature specifically designed for the last 7–14 days of flowering where UV-driven quality enhancement matters most
- 25+ Cycle Lamp Life: Durable quartz glass construction with only 5% degradation at 10,000 hours means the lamp outlasts multiple flowering cycles before replacement
- CRI 90 Broad Spectral Output: High color rendering index ensures the UV-B peaks sit within a spectrally complete output profile for balanced finishing results
