Ushio HiLux Gro CMH Lamp 315W 3000K | 33,000 Lumens | CRI >90

Ushio HiLux Gro 315W CMH 3000K: High-Efficiency Bloom Spectrum at 110 lm/W

The Ushio HiLux Gro 315W CMH 3000K pushes 33,000 lumens at 110 lm/W with a CRI above 90 — the highest efficacy in the HiLux Gro CMH lineup. The 3000K color temperature concentrates spectral energy in the warm red range that drives flowering metabolism, bud development, and fruit set, while maintaining enough blue output for healthy and robust plant structure throughout the bloom cycle. The ceramic µmol output stays within the PAR spectral range for maximum photosynthetic efficiency.

15,000-Hour Bloom CMH Lamp with Consistent Batch-to-Batch Quality

Rated at 15,000 hours, the HiLux Gro 3000K holds its spectral quality and output across a service life long enough for trouble-free operation — especially useful when growing plants that require 24-hour light cycles or high-intensity outputs over extended periods. Operating at 3.15A with a 6–8 minute hot restart time, the lamp fits C182/O or electronic ballasts and mounts in a BU ±90° burning position. Ushio's manufacturing consistency means every lamp in a multi-fixture room delivers the same warm bloom spectrum, which is critical for uniform canopy response and consistent harvest quality across the grow.

Key Features

• 110 lm/W Highest-in-Class Efficacy: Delivers more lumens per watt than the 4200K variant, making it the most efficient lamp in the HiLux Gro CMH lineup
• 3000K Warm Bloom Spectrum: Red-weighted output drives flowering metabolism, bud density, and fruit set while retaining enough blue for balanced plant structure
• 33,000 Lumens: Strong lumen output from a 315W draw provides commercial-grade flowering intensity without the heat load of higher-wattage HPS alternatives
• CRI >90 Full Spectral Output: High color rendering ensures the warm spectrum includes enough spectral breadth for complete photomorphogenic responses during bloom
• 15,000-Hour Rated Life: Long service life with consistent spectral output reduces lamp replacement frequency across commercial flowering rooms
