Fine-tune your grow with the Growlight Direct GLD Sabre 50W UVA — a dimmable UVA supplemental light bar designed to complement your main grow light and help drive specific plant responses. UVA spectrum lighting is commonly used to support faster photosynthesis and metabolite activity, while also encouraging deeper pigmentation and thicker leaves for sturdier growth.
With a long 1030mm bar design, it’s easy to mount across a canopy for broad coverage, and the plug-and-play setup keeps installation simple. The Sabre runs with passive cooling (no fans), so it stays quiet and reliable with fewer moving parts—built for longevity in busy grow rooms.
Note: UVA is best used as a supplemental tool alongside full spectrum lighting. Start with shorter exposure times and increase gradually, as excessive UV can stress plants.
