For rectangular flowering spaces, the HLG 350 Diablo GrowFlux option is currently listed at $598; HLG specifies a 3x5 flowering footprint at 15 inches, up to 330W draw, and 2.80 μmol/J efficacy. For every other fixture, confirm the current option, manufacturer coverage data, controls, electrical requirements, price, and availability on the linked product page.
What wattage LED do I need for a 4x4 tent?
For a 4x4 tent, use the manufacturer PPFD map and stated flowering footprint rather than wattage alone. Many fixtures designed for this footprint draw roughly 400–600W, depending on crop and target intensity. HLG specifies the 350 Diablo for a 3x5 flowering footprint at 15 inches and a maximum draw of 330W, so it should not be described as a 600W 4x4 fixture.
Are LED grow lights better than HPS in 2026?
Neither technology is automatically best for every room. Compare the exact fixtures’ spectrum, efficacy, PPFD distribution, heat load, controls, electrical requirements, purchase price, and replacement needs for the intended canopy.
What does μmol/J mean for grow lights?
μmol/J (micromoles per joule) measures how efficiently a light converts electricity into photosynthetically active radiation (PAR). Good LED lights score 2.5–3.0+ μmol/J. Anything above 2.8 μmol/J is considered high efficiency. The HLG Diablo series, AC Infinity IONFRAME EVO, and Grower's Choice ROI all score 2.8+ μmol/J.
Do I need to dim my LED grow lights?
Not always required, but dimmable lights give you more control. During seedling/early veg stage, run at 40–60% power. During late veg/flower, ramp up to 80–100%. HLG Diablo, Gavita, and AC Infinity IONFRAME all have dimmer controls built in.
What is the best LED grow light brand?
There is no single best brand for every setup. Compare the exact models’ manufacturer output, efficacy, PPFD map, flowering footprint, voltage, controls, warranty, current price, and availability.
HLG vs AC Infinity grow lights — which is better?
Compare exact HLG and AC Infinity models by manufacturer spectrum, output, efficacy, PPFD map, flowering footprint, mounting height, controls, voltage, warranty, and current price. Brand alone does not establish the better fit.
