What is the Optilux X-1800 LED?

The Optilux LED X-1800 light fixture is a powerful, slimline 670W full spectrum LED grow light. It offers a superior performance with better value than other LEDs in its class, all with a 2-year warranty.

Strong and Lightweight Folding Frame - One-Person Assembly

The LED light fixture has a strong and lightweight, anodised, aluminium frame that offers great corrosion resistance. 4x hanging points and the lightweight nature of the folding frame of this LED light fixture make it simple for a single-person to position and hang it.

Eight Bars Of Full Spectrum LED Light

8-bars of high output, full-spectrum, LED light is coupled with on-board manual or remote-controlled dimming. The ability to dim makes this LED the only light source you'll need for the entire life of your plants.

Network Linking - Individually Powered

The Optilux LED X-1800 can be networked and controlled via a compatible lighting controller. Each Optilux LED X-1800 requires its own power source (240V AC).

High Efficiency Samsung/OSRAM LEDS

The Optilux LED X-1800 uses Samsung 301h & OSRAM chipsets as standard. The Samsung LEDs are full spectrum 3K, 4K and 5K. The OSRAM LEDs are 660 nm far-red to aid flowering and the Samsung 301h Chips are the best on the market!

Being solid-state, the LED doesn't use fans to dissipate heat, instead, it uses the aluminium frame and heatsink fins. An IP67 rated housing, makes this light suitable for use in high humidity growing conditions.

Single Light Source throughout the life of your plants

The Optilux LED X-1800 is a powerful full-spectrum LED light fixture. On-board and remote dimming options mean it can be used as the primary light source from seed to bloom in multiple growing systems.
