Growlight Direct GLD Sabre 50W Far Red LED Grow Light Bar | Dimmable R/FR Spectrum Supplemental Lighting | PPFD 20.08 @30cm | Passive Cooled | 587mm Strip

Give your garden a flowering-focused spectrum boost with the Growlight Direct GLD Sabre 50W Far Red — a compact, dimmable Far Red supplemental light bar designed to complement your main grow light and support stronger bloom performance.

Far Red is commonly used as part of a Red/Far Red (R/FR) spectrum strategy, which can help drive a higher photosynthetic response and support blooming and flowering when used correctly in a grow lighting plan. The Sabre bar format makes placement easy for under-canopy, side lighting, or targeted canopy zones—so you can fine-tune your environment without changing your main fixture.

It’s plug-and-play, energy efficient, and built with passive cooling (no fans), keeping it quiet with fewer moving parts for long-term reliability.

Note: Far Red is best used as a supplemental tool alongside full spectrum lighting. For best results, introduce gradually and adjust duration/intensity to suit your crop and growth stage.
