Who This Is For
- You are adding supplemental UVA light because your current full-spectrum fixture is missing the specific resin boost.
- You are integrating these bars into your HLG rig because managing separate cords and timers is a constant headache.
What We Found

- The passive cooling keeps these totally silent, so you avoid adding fan noise to your existing grow space.
What Users Say
- Growers who added these in the final weeks say the increase in resin was visible to the naked eye within days.
- Users with 5x5 tents tell us a single bar provides enough coverage to see results across the entire canopy.
HLG 30 UVA Supplement Bar LED Grow Light - 240V
Take your harvest to the next level by unlocking your plant's full potential. The HLG 30 UVA Supplement Bar is engineered to provide targeted UVA light (365nm & 385nm), a spectrum crucial for boosting terpene, flavonoid, and cannabinoid production in the final weeks of flowering. Adding this bar can significantly enhance the aroma, potency, and overall quality of your yield.
Designed for seamless integration, this 24-inch bar offers direct bolt-on installation for popular models like the HLG Scorpion series, the HLG 750 Diablo, and the high-output HLG 750 Diablo X. It's the perfect upgrade for growers using Horticulture Lighting Group fixtures, from small setups using the HLG 100 V2 to professional-grade commercial arrays. The waterproof, passively cooled design ensures silent, reliable operation without adding heat or complexity to your setup.

FAQs
What is the main benefit of adding a UVA supplement bar?
The primary benefit is an increase in harvest quality. UVA light exposure triggers a defense response in plants, leading them to produce more resin, terpenes, and cannabinoids. This results in enhanced aroma, flavor, and potency. You can learn more about how HLG quantum board technology optimizes plant growth.
When should I use the HLG 30 UVA bar in my grow cycle?
For best results, use the UVA bar during the final 2-3 weeks of the flowering stage. It is typically run for 2-4 hours per day in conjunction with your primary light's cycle to simulate the intense, natural sunlight that plants use as a signal to protect their flowers with resin.
Is this a standalone grow light?
No, the HLG 30 is a supplemental light only. It is designed to work alongside a primary, full-spectrum light fixture like the HLG 750 Diablo ES or the HLG 350 Diablo. It does not provide the necessary light spectrum for vegetative growth on its own, which is better served by dedicated units like the HLG 250 Veg Pro or the compact HLG 65 V2 Veg.
How do I install the UVA bar?
Installation is flexible. It comes with two hangers for independent suspension at your desired height. It also features a simple bolt-on design for direct attachment to compatible HLG fixtures, including the HLG 550, 600 Rspec, 650R, and Scorpion models.
Can I use this with a non-HLG grow light?
Absolutely. While it's optimized for easy integration with select Horticulture Lighting Group models, you can use the included hangers to suspend it independently in any grow tent or room, regardless of your primary light's brand.
