The 30W LED Bar from 4Twenty with Full Spectrum is developed for growers looking for a compact and versatile lighting solution for the entire grow cycle. Thanks to its balanced full-spectrum light, this LED Bar supports both the growth and flowering phases, allowing one fixture to be used from seedling to harvest.

Due to its slim design and limited heat development, the LED Bar can be placed close above the crop. This makes the lamp suitable as main lighting for small grow areas and as supplementary lighting in larger setups.

Suitable for

• Growth and flowering phase
• Small grow tents
• Herbs and leafy greens
• Compact grow setups
• Supplementary side or under lighting
• Hobby and professional growers

Recommended settings

The 420 LED Bar Full Spectrum delivers efficient light intensity directly and can be placed close above the crop due to its limited heat development.

Seedlings & young plants

• 15-20 cm above the crop

Growth phase

• 10-15 cm above the crop

Flowering phase

• 10-15 cm above the crop

Always check how the crop reacts to the light intensity and adjust the distance if necessary.

Complete grow cycle with one lamp

The full-spectrum light combines the most important light waves for both vegetative growth and flowering. This makes the 420 LED Bar Full Spectrum a simple solution for growers who do not want to switch between different light sources during the grow cycle.

Flexibly expandable

Thanks to the Daisy Chain functionality, multiple LED Bars can be easily linked to form a larger lighting system. This allows the lighting to grow with the available grow space.

The Full Spectrum LED Bar can also be combined with the 420 LED Bar Grow, allowing additional grow light to be added when mother plants, cuttings or grow spaces require it.

Waterproof and maintenance-free

The IP66-certified housing protects the electronics from moisture and dust. Thanks to passive cooling, the lamp operates completely silently and no maintenance is required for fans or other moving parts.

Build your ideal light source yourself

With the handy optional LED Bar Mounting Kit, you can easily combine multiple LED bars (of the same length) into one powerful fixture. Attach up to 10 LED bars to two sturdy aluminum brackets and connect the lamps to each other with the Daisy-chain connectors. This way, you can quickly create one large, powerful lamp, suitable for any grow space.
