What we measured
The three artifacts a lighting plan is actually drawn from. Every figure below comes off our own spec sheet; where we do not have a measurement, the page says so instead of estimating.
Coverage & PPFD
Rated flowering footprint, 4 × 4 ft. Both readings are µmol/m²/s measured 1 ft from canopy (mounting range 6-24 in). The shading illustrates centre-to-edge falloff; it is not a measured grid. A full PPFD map at your mounting height comes with the quote.
1-channel spectrum
Full balance spectrum - Samsung LM281B white + 450nm blue + 660nm deep red (no UV or far-red channel).

The production workhorse. 2,464 µmol/s over a 4ft × 4ft flowering bench, on one dimmer, from a fixed full-balance spectrum — 2,968 diodes of Samsung LM281B full spectrum with 660nm deep red, and no UV or far-red diodes. Fewer parameters to manage, and more photons per fixture than the three-channel 720W over the same bench. 1,320W HPS replacement.
What you get
- 2,464 µmol/s, 880W at 277VAC — 24% more output than the three-channel TF 720W PRO over the same bench.
- 719 µmol/m²/s average PPFD at 12 inches, peaking at 946 under the fixture.
- Fixed full-balance spectrum: 2,968 diodes, Samsung LM281B full spectrum plus 660nm deep red. No UV, no far-red.
- Single-channel dimming, 0-100% at the knob or over RJ12 group control — one number to set per zone.
- 4ft × 4ft flowering, 5ft × 5ft vegetative coverage, 120° beam.
- AC 110-277V input, 3.2A at 277V, UL-listed driver, power factor at or above 0.95.
- Passive cooling to 40°C ambient; IP65, flicker-free; 1120 × 1120 × 50 mm, folds flat to ship at 16.35 kg gross.
- Five-year standard warranty, L90 beyond 50,000 hours.

Before you spec it
Why would I choose a fixture with no UV or far-red?
Because a lot of commercial rooms do not use them. If your recipe is a fixed photoperiod and a fixed spectrum, the UV and far-red channels on the PRO fixtures are capability you never dim. The SF puts the fixture's power budget into photons instead: 2,464 µmol/s from 880W against 1,980 µmol/s from the 720W three-channel fixture on the same bench.
SF 880D ECO or SF 660D ECO?
Same fixture, same 4ft × 4ft footprint, two intensity steps: 2,464 µmol/s here against 1,848 µmol/s on the SF 660D ECO — a 719 versus 539 µmol/m²/s canopy average. Take the 880 for flowering with CO₂, the 660 for veg, mothers, or flowering rooms without enrichment.
Can I add UV or far-red later without replacing the fixture?
Yes, as separate fixtures. Supplemental bars hang between the top lights and run from the same GC001 controller on their own channel, which keeps the top-light spectrum fixed and the supplemental dose independent. That keeps three-channel capability out of every top light in the facility, which is worth pricing both ways.
Does it group-control the same way as the PRO fixtures?
Yes. Same RJ12 interface, same daisy-chain, up to 100 fixtures per controller. A single room can mix SF ECO and TF PRO fixtures on one GC001, grouped into separate zones.
