Maxibright Daylight Supplementary Strips – UV, UVA & UVB, and Far-Red LED Add-On Bars

Maxibright Daylight Supplementary Strips are designed to expand the spectrum of your main grow light and fine-tune your setup for better performance. Available in UVA, UVA & UVB, and Far-Red versions, these add-on LED bars help you target parts of the spectrum that many standard LED grow lights do not fully cover.

They can be mounted directly between the bars of compatible Maxibright Daylight LED fixtures using the supplied brackets, or hung independently in the exact area where you want extra spectral support.

Key Benefits

• Targeted spectrum enhancement; choose UV, UVA & UVB, or far-red depending on your goals
• Improves crop quality; ideal for growers refining aroma, flavour, density and finish
• Flexible installation; attach to compatible Maxibright fixtures or hang separately
• Designed to complement Daylight LEDs; a natural upgrade for 480W and 660W Daylight setups
• Plug-and-play format; simple to integrate into an existing grow room
• IP65 protection; better suited to humid grow environments
• Supplementary lighting without overhauling your main fixture; improve performance without replacing your primary light

Why You Need It

Most full spectrum LEDs do a solid job across the core PAR range, but there are still areas of the spectrum that can be used more deliberately when you want to push quality or adjust plant response.

That is where supplementary strips come in. Instead of changing your entire lighting system, you can add the exact wavelength you want more of. This gives you more control over how your plants respond in flower, how compact they grow, and how hard your existing fixture works across the full cycle.

Choose the Right Version

UVA
UVA is commonly used by growers looking to push plant quality and encourage a stronger stress response. In practical terms, it is often chosen to help improve essential oil production, aroma and overall finish.

UVA & UVB
This version adds UVB alongside UVA for a stronger supplementary UV effect. It is typically chosen by growers who want to push quality harder and encourage tighter, denser flowers. Because UVB is more intense, it should be used more carefully than standard UVA supplementation.

Far-Red
Far-red is used to fine-tune plant response and can support faster photosynthetic activity when combined with red light. It is also popular for end-of-day far-red strategies and for growers looking to influence flowering behaviour or increase productivity through better spectrum balance.

How to Set Up

• Choose the spectrum type that suits your goal: UVA, UVA & UVB, or Far-Red
• Attach the strip to a compatible Maxibright Daylight LED using the supplied brackets, or hang it separately
• Position the strip so the extra wavelength reaches the target area of the canopy
• Use supplementary lighting alongside your main fixture, not as a replacement for it
• Increase exposure gradually, especially when using UV-based strips

Top Tip

Supplementary strips work best when used to fine-tune an already strong main lighting setup. If you are adding UV, start gently and build exposure gradually rather than running it hard from day one.
