Adjusta-Watt 720W Retro LED Grow Light Bar Fixture

Bar-Style Coverage and Serious Output From a Compact Fixture

The Adjusta-Watt Retro LED takes the bar-style LED layout that growers switched to for its even canopy coverage and packs it into a fixture small enough for a tent. Output is a genuine 1890 PPF from 720W – around 2.6 umol/J – so you are not compromising on intensity to get something that fits. It runs on a premium digital dimmable ballast, and a splitter cable lets a single ballast drive two fixtures where you need to spread the light further.

Key Benefits

• 1890 PPF at 720W, roughly 2.6 umol/J, from a compact bar-style body
• Even coverage across the canopy rather than a hot centre and dim corners
• Full-cycle spectrum blending white, cool blue, warm and far red for seedling through to harvest
• Over 50,000 hours of life with minimal output degradation
• Silent and cool running, so it adds nothing to your noise or heat problems
• Digital dimmable ballast with an optional splitter cable to run two fixtures from one ballast

Underlit Corners and Stretchy, Airy Tops

Single-point fixtures concentrate light in the middle of the tent, which is where excessive stretch under the lamp and airy buds at the edges come from. Spreading the same photons across a bar layout gives the whole canopy a usable light level, so lower sites fill out instead of being written off. Dimming down for propagation also stops young plants being blasted at a stage when low yields usually trace back to early stress.

How to Use

• Position close to the canopy and adjust the distance as plants fill out
• Minimum 15cm between light and canopy in a 100 x 100cm space
• Minimum 30cm in a 120 x 120cm space
• Start at 25-50% power and increase gradually as plants acclimatise
• Always start at 25% for propagation
