Advanced Red Spectrum for Fruiting Plants

These T8 LED grow bulbs deliver a photosynthetic photon flux of 34 micromoles per second using an advanced red light spectrum. The spectrum is designed for mature plants at the fruiting or flowering growth stage. It allows plant pigments to optimize light harvesting for photosynthesis and growth. The white light appears natural to the human eye for easier plant inspection.

Direct Replacement for 48 Inch Fixtures

Installation is a direct swap into existing 48 inch shop light tube fixtures. The bulbs are designed to sit 6 inches above seedling trays or plants. A typical schedule runs the lights for 12 hours per day. Rated lifespan reaches 25000 hours under normal use.

Verify Fixture Compatibility Before Purchase

Confirm your current fixtures accept standard T8 LED tubes of 48 inch length. Ensure the mounting height allows roughly 6 inches of clearance above the canopy. The advanced red spectrum targets flowering and fruiting stages rather than early vegetative growth. Buyers needing a spectrum for seedlings or leafy greens should consider a different light recipe.
