Replacement Reflector for Dimlux Expert 1000W HPS Fixture - Restore Full Reflectivity
Best for: Dimlux Expert Series 1000W HPS owners whose reflector liner has dulled with age and is no longer performing at its best.
Our thoughts
A reflector liner is one of those parts that quietly loses performance over time without it being obvious - the light still comes on, it just isn't bouncing back at your plants as efficiently as it used to. Swapping the liner is a cheap way to claw back light output on a fixture that's otherwise still doing its job fine.
This is a genuine replacement reflector liner for the Dimlux Expert Series 1000W HPS fixture, using the same Alpha Optics 98 Miro-Silver coated aluminium as the original. Miro-Silver reflective material is rated at around 98% reflectivity when new, achieved through several nanometre-thin optical coatings applied to the aluminium surface. The reflector follows Dimlux's Single Bounce Clear Sight (SBCS) design principle, with adjustable side reflectors to improve overlap and reduce light lost to the fixture walls.
Reflectivity on any reflector liner gradually declines as the surface discolours and dulls with heat and age - typically noticeable after roughly a year of regular use. Replacing the liner on that kind of schedule restores the fixture's light output without needing to replace the whole unit. This is a fixture-specific replacement part, not a universal reflector, and is designed to fit the Dimlux Expert Series 1000W HPS fixture only.
How it compares
Replacement reflector liners are a fixture-specific part, so the real comparison is against the cost of not replacing it, or against buying a new fixture entirely.
- Against buying a whole new Dimlux Expert fixture, replacing just the reflector liner is a far cheaper way to restore lost reflectivity on an otherwise working unit.
- Against premium open-reflector designs like Adjust-a-Wings, Dimlux's SBCS design with adjustable side wings pursues a similar goal of minimising wall losses, though the two aren't interchangeable between fixtures.
- Running an old, discoloured reflector rather than replacing it means losing light efficiency for the sake of a relatively small saving on a genuinely low-cost part.
A sensible, low-cost way to keep an existing Dimlux Expert fixture performing as designed.
Usage guidance
A straightforward swap, but a few points are worth knowing before fitting.
When to replace
As a general guide, replacing the liner roughly every 12 months of regular use helps maintain consistent light output, though visible discolouration or dulling of the surface is the clearest sign it's due.
Fitting
Always disconnect and allow the fixture to cool fully before removing the old liner and fitting the replacement, following the fixture's own access points for the reflector.
Compatibility
This liner is designed specifically for the Dimlux Expert Series 1000W HPS fixture - check your fixture model before ordering, as reflector liners are not interchangeable between different fixture ranges.

Our take
This is a small, low-cost part that quietly does an important job - keeping your Dimlux Expert fixture reflecting light as efficiently as the day it was new. It's a straightforward maintenance buy rather than an upgrade, and one that's easy to overlook until output starts to drop.
