Full Spectrum 4K Output: Balanced daylight spectrum ideal for vegetative growth and healthy plant structure.

High PAR Performance: Produces approximately 960 µmol/s of usable plant light output.

Excellent CRI Rating: 97% Colour Rendering Index for a more natural light spectrum.

Enhanced Blue Spectrum: Encourages tighter internodes and bushier plant growth.

CMH Technology: Improved light quality compared to standard HPS lamps.

Energy Efficient: Delivers around 1.6 µmol/J efficiency for strong performance with reduced energy waste.

Compatible With 600W Ballasts: Works with both magnetic and digital 600W systems.

E40 Screw Fitting: Fits standard 600W grow light reflectors and fixtures.

Ideal for Vegetative Growth: Perfect for propagation, veg rooms, and mother plants.
The DAYLIGHT 600W 4K Lamp uses ceramic metal halide technology to generate a high-intensity full-spectrum light output that more closely resembles natural sunlight than traditional HPS lamps. Its enhanced blue spectrum helps promote compact vegetative growth, stronger stems, and healthier leaf development.

The lamp produces high levels of photosynthetically active radiation (PAR), allowing plants to photosynthesise more efficiently and develop improved structure and vitality. CMH lighting also helps improve terpene, flavonoid, and essential oil production while maintaining excellent overall plant quality.
Install Carefully: Screw the lamp securely into a compatible E40 reflector fitting.

Use Compatible Ballast: Operate with a suitable 600W digital or magnetic ballast.

Vegetative Stage Recommended: Best suited for propagation and vegetative growth phases.

Allow Warm-Up Time: The lamp may take several minutes to reach full output.

Maintain Proper Distance: Position above the canopy at a safe distance to avoid light stress or heat damage.

Do Not Dim: This lamp is not designed for dimmable ballast settings.

Replace Periodically: Replace after extended use to maintain maximum PAR output and spectrum quality.

Best Practice: Use with adequate ventilation and reflective surfaces for optimal performance.
