Solacure Flower Power Lamp Fixture — UVB Supplemental Lighting That Triggers the UVR8 Response
Best for: Growers wanting to boost resin production and reduce pest pressure without replacing their main lighting system
Our thoughts
This is the number one selling UVB system in the US, Canada, and Europe for good reason. Solacure's patented spectrum—especially the 280-300nm range that triggers the full UVR8 protein—actually works. Not a gimmick. Real results, and the 30-day money-back guarantee lets you prove it to yourself.
The Solacure Flower Power is a supplemental UVB lamp fixture designed to trigger the UVR8 protein in plants, stimulating them to produce more protective compounds—what growers see as noticeably frostier, denser crop material. Unlike generic reptile bulbs or basic UV systems, Flower Power produces the full UVB spectrum down to 280nm (most competitors only hit 300nm+), meaning you get the wavelengths that actually activate the UVR8 response. Add it to your existing setup during flowering, and you're looking at 20-35% increases in resin production, with many growers reporting 35%+ gains. Beyond that, UVB also suppresses mould, mildew, and pest populations—they can't survive in a high-UV environment.
How it compares
UVB supplemental lighting sits in its own category, but here's the honest breakdown:
-
vs. Reptile bulbs: Solacure is 20x stronger and produces 280-320nm UVB spectrum, not just 300nm+. Reptile bulbs are underpowered for triggering the full UVR8 effect
-
vs. AgroMax Pure UV (T5): Both systems work, but Solacure has more available power (21-100w flexibility) and built-in reflectors. AgroMax has better ballast availability on the UK market
-
vs. LED UV bars: Standard LED grow lights don't include UVB. Specialist UV LEDs exist but don't deliver the intensity or spectrum efficiency of fluorescent UVB systems like Flower Power
-
vs. doing nothing: Every serious grower we talk to who's tried proper UVB can't go back. The difference is visible
Usage guidance
UVB is powerful and needs respect. Run it wrong and you'll damage your crop. Run it right and you'll see results.
Fixture placement and distance
Mount the lamp at the same height as your main lighting, typically 12-24 inches from the canopy. You can run closer (6 inches, but reduce exposure time) or further (up to 6 feet, but increase time). Built-in reflectors mean you don't need separate reflector kits.
Power settings and coverage ratio
Flower Power runs at 21 watts or up to 100 watts depending on your ballast setup. Run two fixtures for every 600-1000w HID light source (or equivalent LED wattage). Link multiple fixtures together using the plug-and-play system—up to 8 can be daisy-chained from a single power outlet.
Starting protocol—critical for avoiding damage
Begin UVB on day one of flowering. Start conservatively: two 15-minute sessions per day, spread across your photoperiod (morning and evening works well). Every couple of days, increase each session by 15 minutes. Work your way up to 2-6 hours total daily exposure. The moment you see light wilting on the top leaves, pull back 30 minutes and lock that duration in—that's your sweet spot for your specific setup and crop variety.
Water on leaves = UV burn
This is critical and catches growers out: UVB will burn any leaf material with moisture on it. Unlike LED lights, water beads aren't forgiving here. Avoid misting, splashing, or humid conditions directly under the fixtures. Keep foliage dry during and for several hours after UV exposure.
Lifespan and replacement
Lamps last up to 3 flowering cycles for peak resin production, but will continue running until they finally fail (roughly 3000-4000 hours). You can keep using them for mould and pest suppression long after output drops.

Who this is for
- Growers running LED systems who want to add the UVB spectrum their lights don't provide
- Experienced growers chasing higher resin density and compound production
- Anyone running mould-prone environments where UVB's antimicrobial properties matter
- Growers with persistent pest issues looking to reduce population pressure naturally
- Serious operators where the investment in proven UVB pays for itself in yield quality
Not recommended for beginners without UVB experience—the exposure protocol has a learning curve, and incorrect use can damage a crop quickly. If you're new to UVB, start conservatively and adjust upward slowly.
Our take
Solacure Flower Power is the number one selling UVB system globally for a reason: it delivers the spectrum (280-320nm) that actually triggers the UVR8 protein, and the results are visible. Frostier material, denser structure, pest suppression, mould prevention—all proven. It's not cheap, but the 30-day money-back guarantee means you can test it yourself risk-free.
The main thing: respect the protocol. Start low, increase slowly, keep foliage dry, and you'll see why growers rate this. Cut the corners and you'll learn an expensive lesson. Used properly, worth picking up while stock lasts.
