Grow Light Reflectors

A high-quality grow light reflector can be the difference between patchy, uneven canopy development and a dense, uniform harvest. The reflector determines how efficiently your bulb’s light output is directed downward to your plants — the wrong design wastes precious lumens on walls and fixtures rather than canopy. We stock a comprehensive range of reflectors for HPS, MH and CDM systems.
Adjust-a-Wing — Flexible, Wide-Spread Reflectors
Adjust-a-Wing reflectors are one of the most popular designs in UK grow rooms and for good reason. The adjustable wing system allows growers to change the spread angle of the reflector, delivering a wider footprint at larger wing angles and a more concentrated output at tighter settings. This flexibility makes Adjust-a-Wing ideal for rooms where hanging height varies or where you need to cover a non-standard canopy shape.
The patented design also places the bulb slightly above the reflector surface rather than inside it, reducing heat build-up on the reflector and allowing closer placement to the canopy. The result is denser light at lower heights without risk of heat stress.
Euro Reflectors and Parabolic Designs
The Euro (hammered or dimpled aluminium) reflector is the standard workhorse in tent growing. Its highly reflective interior scatters light evenly across a rectangular footprint, making it well-suited to standard 1.0m × 1.0m and 1.2m × 1.2m tents. Parabolic reflectors use a curved, highly polished surface to project a focused beam of light with maximum intensity at canopy level — preferred by growers with taller rooms where more focused penetration is beneficial.
When choosing a reflector, match its coverage area to your tent size. An undersized reflector creates hotspots and uneven growth. An oversized reflector wastes light on tent walls. We have been advising UK growers on reflector selection since 2017. Browse our full reflector range below.
