Omega 315W Euro Reflector 5m IEC Cable — Open Design CMH Reflector for Efficient Growing
Best for: Budget-conscious growers wanting 315W ceramic metal halide efficiency without premium brand pricing
Our thoughts
The 315W CMH technology is genuinely impressive — you get close to natural spectrum light with HID intensity on less power. The Euro reflector design is proven kit that's been shifted by the million. This Omega setup sits in that sweet spot where you're not paying Maxibright money but still getting proper 315W ceramic discharge performance. One we recommend a lot for growers looking to supplement HPS systems or cover a small space efficiently.
The Omega 315W Euro Reflector is a tried-and-tested open-design reflector hood purpose-built for 315W ceramic metal halide lamps. It comes pre-assembled with a 5 metre IEC cable, ready to hang straight out of the box. The hammered aluminium finish and central spine design maximise light reflection while the open ends let hot air escape freely — meaning you can run the lamp closer to your plants without thermal stress. It's simple, reliable kit that does exactly what a reflector should do.
How it compares
The 315W CMH reflector sits between entry-level and mid-tier lighting.
- Open Euro design vs enclosed cool tubes — better heat dissipation, easier air extraction
- Lower cost than Maxibright or Philips-bundled systems
- Higher spectral quality than traditional 400W HPS — closer to natural sunlight
- More efficient PAR per watt than older HID technology
- Lighter power draw (315W) but covers 0.75–1m² effectively
In simple terms: you're getting ceramic metal halide quality at a price that doesn't rinse your budget.
Usage guidance
Installation
Hang the reflector using rope ratchets above your growing area. Insert your 315W CDM lamp into the E40 socket and screw firmly. Plug the IEC connector into a compatible 315W CMH ballast and switch on. Critical: run the lamp continuously for a minimum of 15 minutes on first startup — this allows the ceramic metals and salts to fuse properly.
Coverage area
This reflector covers 0.75m² to 1m² effectively, making it ideal for small grow tents or supplementing existing 600W HPS systems across a larger space.
Lamp compatibility
Works with any 315W CDM (ceramic discharge metal halide) lamp. Choose 4000K (blue spectrum) for vegetative growth or 3000K (red spectrum) for general-purpose growing. Note: you must use a 315W CMH ballast — standard HPS ballasts won't work.
Heat management
The open design is the key advantage. Hot air rises and escapes freely, so you can position the lamp closer to foliage than enclosed fixtures. Extract the warm air with your ducting fan and filter as normal.

Who this is for
- First-time growers wanting 315W CMH efficiency without guessing ballast compatibility
- Experienced growers supplementing 600W HPS systems across larger spaces
- Budget-conscious operators who want proven technology at a lower price point
- Anyone growing in small tents (1m²) or tight spaces where heat management matters
- Growers who prefer the open reflector design for simplicity and heat control
Our take
The Euro reflector is proven kit — millions of growers use it because it works. Pair it with a 315W CDM lamp and a compatible ballast, and you've got a proper, efficient lighting system that won't overcomplicate things or drain your budget.
If you're building a small-space setup or supplementing existing HPS lighting, this is worth picking up while clearance stock lasts. Simple, reliable, and does exactly what it should, day in, day out.
