LED Grow Lights
Discover our full range of full-spectrum LED grow lights, built for energy-efficient growing without compromising on output. From compact propagation panels to powerful 720W-1000W fixtures, we stock leading brands including LUMii, DimLux, Telos, Lumatek, Maxibright, and DLI. LED grow lights run cooler and more efficiently than traditional HID lighting, making them ideal for growers looking to reduce running costs while maintaining strong PPFD across vegetative and flowering stages.
Why growers are switching to LED
LED grow light technology has matured significantly over the past decade. Where early LED fixtures struggled to match HPS output, modern quantum-board and multi-bar LED designs — like our DimLux Xtreme and Lumatek Zeus ranges — now deliver comparable or superior PPF (photosynthetic photon flux) per watt, while running at a fraction of the heat output. This means less strain on your ventilation system, lower electricity costs over a grow cycle, and often a longer fixture lifespan (many rated 50,000+ hours) compared to HPS bulbs needing annual replacement.
Full spectrum vs targeted spectrum
Most modern LED fixtures use a "full spectrum" approach — blending white, red, and sometimes far-red or UV diodes to cover the complete range a plant uses across its life cycle, rather than requiring separate vegetative and flowering bulbs like traditional HID. Some ranges, like DimLux's +NIR variants, add near-infrared specifically to influence plant structure and stretch — useful for certain training styles, but worth avoiding if you want to keep your canopy compact.
Understanding PPF and efficacy
When comparing LED fixtures, two numbers matter most: PPF (total light output, measured in µmol/s) tells you how much usable light a fixture produces, while efficacy (µmol/J) tells you how efficiently it converts electricity into that light. A higher efficacy figure means more light per watt of electricity — directly translating to lower running costs for the same output.
Fixed vs adjustable-bar fixtures
Some of our LED ranges, like the Maxibright Daylight 660W, use movable LED bars that let you adjust spacing and angle to match your canopy shape as plants grow. Others, like compact propagation panels, use a fixed layout suited to a specific footprint. If you're growing multiple plant sizes or shapes in one space, an adjustable-bar fixture offers more flexibility over the grow cycle.
Dimming and control
Most of our digital-driver LED fixtures support 0-10V dimming, letting you scale output up gradually as seedlings mature into full vegetative growth, then dial in your ideal intensity for flowering. Fixtures with wireless mesh control (like Telos's Pro Mesh system) let you manage dimming across dozens or even hundreds of fixtures from one interface — particularly useful for larger, multi-room setups.
FAQ
Can LED fully replace HPS in my grow room?
Yes, in most modern setups — today's higher-output LED fixtures can match or exceed HPS yield potential while running cooler and more efficiently. The main consideration is upfront cost, since quality LED fixtures typically cost more than an equivalent HPS kit, though this is often recovered through lower running costs over time.
Do I need a different LED fixture for veg and flower?
Not usually — full-spectrum LED fixtures are designed to cover the entire grow cycle with one fixture, unlike traditional HPS/MH setups that often use separate bulbs for each stage.
How close can I place an LED fixture to my canopy?
This varies significantly by fixture wattage and design — always check the manufacturer's recommended hanging distance, since LED fixtures can still cause light bleaching or heat stress if placed too close, even though they run cooler than HID lighting overall.
What does "quantum board" mean?
A quantum board is a flat, evenly-distributed LED panel design (rather than clustered chips), producing more uniform light coverage across the canopy with fewer hot spots — common in modern high-efficiency LED fixtures like our LUMii Black Blade range.
