Iluminar LED & HPS Grow Light Fixtures
Iluminar is a commercial horticultural lighting brand with a product lineup spanning LED bar arrays, double-ended HPS fixtures, and CMH systems for indoor and greenhouse production. Their focus is providing commercial-grade fixtures at competitive price points -- targeting the commercial grower who wants proven fixture performance without the premium pricing of category leaders like Gavita. Iluminar fixtures are found in commercial indoor operations across North America and have built a track record for reliability and photometric performance at their price tier.
Iluminar IL Series LED Bar Arrays
Iluminar's IL Series LED bar arrays cover the 600-1000W commercial canopy range using Samsung LM301H diodes and Inventronics or Meanwell drivers -- the same core components used by the category's top-tier brands. IL Series fixtures achieve 2.7-2.9+ umol/joule efficiency, are dimmable via 0-10V analog input for TrolMaster and compatible controller integration, and are available in configurations covering 4x4 to 5x5 ft canopy footprints. Published PPFD maps are available for each model -- use these with our PPFD Calculator to confirm coverage for your specific canopy dimensions before purchasing.
Iluminar HPS & CMH Fixtures
Iluminar produces double-ended HPS fixtures in 600W and 1000W configurations for growers maintaining existing DE HPS infrastructure, and CMH (315W and 630W) complete systems for spectrum-quality applications. Their DE HPS line uses electronic ballasts with multi-watt capability for output adjustment between 600W and 1000W. For growers comparing LED vs. DE HPS economics, use our Electricity Cost Calculator to model the specific payback period for your facility. Expert support available.
Iluminar Grow Lights FAQ
How does Iluminar compare to Gavita and Growers Choice?
Iluminar occupies the competitive mid-tier of commercial LED -- similar Samsung LM301H components and efficiency ratings (2.7-2.9 umol/joule) to Gavita and Growers Choice, at a lower price point. Gavita has the most established commercial service network and the EL2 Master Controller ecosystem for large multi-fixture facility management. Growers Choice has the most grower community documentation and competitive pricing. Iluminar offers similar photometric performance at a competitive price with 5-year warranty coverage -- a practical choice for growers building or expanding commercial facilities where capital cost is a primary consideration.
What canopy size does the Iluminar IL Series cover?
Iluminar IL Series fixtures cover 4x4 to 5x5 ft flowering canopy footprints depending on the specific model wattage. Published PPFD maps are available for each fixture at multiple hanging heights -- use these with our PPFD Calculator to verify coverage for your exact canopy dimensions and target intensity. For 4x4 ft coverage at 900-1,100 umol/m2/s, the 600-650W IL Series model is appropriate; for 5x5 ft at similar intensity, the 700-800W model is the right fit.
Are Iluminar LED fixtures compatible with TrolMaster?
Yes -- Iluminar IL Series LED fixtures accept 0-10V analog dimming input, which is compatible with TrolMaster Hydro-X Pro's 0-10V analog output. This enables automated dimming schedules, temperature-triggered light reduction, and remote intensity adjustment via the TrolMaster app. Connect the 0-10V dimming cable from each Iluminar fixture to the Hydro-X's analog output channels for coordinated multi-fixture dimming.
How often should Iluminar HPS bulbs be replaced?
Replace Iluminar DE HPS bulbs every 10,000-12,000 hours of operation -- approximately 12-18 months at 18-hour daily use or 18-24 months at 12-hour daily use. DE HPS bulbs lose 20-30% of initial output by this point while still physically functioning. Continuing to run degraded-output bulbs produces lower yield from the same electricity cost. Replacement Iluminar and Philips GreenPower DE bulbs are available in our grow light bulbs collection.
Does Iluminar offer a warranty on their fixtures?
Iluminar offers a 5-year limited warranty on their current IL Series LED fixtures covering manufacturing defects and LED failure. Their HPS and CMH fixture warranty terms vary by product line -- check the specific product documentation for warranty coverage details. For commercial installations where warranty service turnaround time is a production consideration, confirm replacement fixture availability with our commercial team before committing to a large installation. Call 888-815-9763 for commercial account support and warranty questions.
