Supernova Reflector - Maxibright Closed-End HPS Reflector
Best for: Growers running an HPS or CDM lamp who want maximum, even light spread across the canopy from a straightforward closed-end reflector.
Our thoughts
Closed-end reflectors like this one aren't fancy, but the dual parabolic shape genuinely pushes more light down toward the canopy instead of scattering it sideways up the tent walls. If you're not running an air-cooled setup, this is a solid, no-nonsense way to get more usable light per watt out of your existing HPS lamp.
The Maxibright Supernova is a closed-end reflector built from polished, hammered dimpled anodised aluminium, designed to maximise light output and spread across the grow space. The dual parabolic shape bounces light from the lamp downward toward the canopy rather than losing it sideways, and the dimpled surface helps scatter light evenly rather than creating hot spots directly under the bulb.
It's suitable for lamps from 250W up to 1000W, so it covers most HPS and CDM setups without needing a different reflector for each wattage. It comes with a hanging chain and an IEC connection to link straight to your ballast.
How it compares
It sits in the standard closed-end reflector category, distinct from air-cooled or adjustable-wing designs.
- Simpler and cheaper than air-cooled reflectors, since it has no glass panel or duct connections to manage heat
- Different approach to Adjust-A-Wings' Defender or Hellion reflectors, which use an open, adjustable-wing design rather than a fixed closed-end shape
- Comparable in role to Omega's standard reflectors, though the Supernova's dual parabolic profile is aimed at tighter, more even light spread
A dependable, budget-friendly reflector if you don't need air-cooling or an adjustable wing shape.
Usage guidance
Fitting a lamp
Fit your HPS or CDM lamp (250W-1000W) into the lampholder and connect the reflector to your ballast via the IEC connection.
Hanging
Use the supplied chain to hang the reflector at a height suited to your lamp wattage and tent size, adjusting based on canopy heat and light spread.
Cleaning
Wipe the dimpled aluminium surface periodically to keep reflectivity high - dust build-up reduces the light actually reaching your plants.

Who this is for
- Growers running a standard HPS or CDM setup without ducted air-cooling
- Anyone wanting even canopy coverage rather than a tight, hot-spot-prone open reflector
- Growers upgrading from a basic reflector to something with a more efficient reflective surface
Our take
It's not the flashiest reflector on the shelf, but the dual parabolic shape and dimpled aluminium genuinely do a better job of spreading light evenly than a lot of basic reflectors at this price point. For a non-air-cooled setup, it's a sensible choice.
Does exactly what it should, day in, day out, across a full flowering cycle.
