Power meets precision, in every product
The ParFX Ultra pairs ultra-high output and exceptional uniformity with a spectrum matched to your crop, across a family of four products on one form factor.
Engineered spectrum, every product
Fixed engineered recipes across the family, or dynamic 2-, 3-, or 4-channel tuning on the Ultra Max. Spectrum matched to your crop and stage.
Batwing distribution
Medium-wide and ultra-wide lens options deliver exceptional uniformity, so you can space fixtures wider and use fewer per growing area.
Plug-and-play platform
An integrated driver and standard horticultural power connectors make installation simple. Compatible with all dimming systems generating a 0-10 volt signal.
MeshIQ wireless compatible
Pair with the MeshIQ platform for zonal wireless control, compatible with Climate Control Computers running the Horti Lighting Protocol. No new control cabling to run.
Four products, one form factor
Same form factor across the family; output and configurability step up with each product. Pick the product that matches how your facility runs, or share a direct link to it with your sales manager.

Engineered spectrum, every product
Pick from engineered fixed recipes across the family, or dynamic 2-, 3-, or 4-channel tuning on the Ultra Max, with independent red, far-red, white, and blue channels you can adjust across growth stages. Spectrum is matched to your crop and stage, not a one-size-fits-all luminaire.
Batwing distribution
The ParFX Ultra lens is optically engineered for a medium-wide (standard) or ultra-wide batwing distribution, delivering exceptional uniformity. A wider distribution lets you space fixtures farther apart and use fewer per growing area.
Engineered thermal management
Convection currents draw cool air into the slots along either end of the luminaire. The air passes through integrated aluminum fins that span its length, drawing heat away from the LEDs and the electronics compartment for optimal passive thermal management.
Mounting options
An integrated driver, standard horticultural power connectors, and intuitive mounting, including the availability of custom bracket mounting solutions, allow for easy installation in both new and retrofit applications, in full LED or hybrid configurations. The ParFX Ultra mounts to the truss you already have; your installer selects the bracket that fits your greenhouse structure or indoor racking.

Peak photon flux and efficacy are the highest published values per product (R95:B5 / R90:W5:B5 recipes, measured 350 to 800 nm); actual output depends on the selected recipe and voltage. Only the 4-channel Ultra Max is fully dynamic and tunable. Values accurate to plus or minus 10 percent. Full per-channel specifications are in each product's spec sheet.

ParFX Ultra questions, answered
What is the difference between the ParFX Ultra products?
All four products share one form factor. Ultra Lite is single-channel at 600W for the lowest capex; Ultra (750W) and Ultra Plus (1040W) step up output for higher-DLI crops; Ultra Max is the highest output in the family (up to 1200W on channel 1) and the only one available as a fully dynamic 4-channel fixture.
Which ParFX Ultra is tunable?
Only the 4-channel Ultra Max is fully dynamic and tunable across growth stages, with independent red, far-red, white, and blue channels. Every other product ships with a fixed engineered recipe matched to your crop; custom recipes are available on request.
What lens options are available?
The lens is optically engineered for a medium-wide (standard) or ultra-wide batwing distribution. The wider option lets you space fixtures farther apart and use fewer per growing area while keeping uniformity high.
Can the ParFX Ultra be controlled wirelessly?
Yes. Any ParFX Ultra pairs with the MeshIQ wireless platform for zonal dimming and scheduling with no new control cabling. Fixtures also dim over 0-10V (single channel) or digital dim to off (multi-channel).
