Dutch Lighting APEX 800 FS-DC LED Toplight | 2100 µmol/s | 208-400V

Commercial Greenhouse LED Grow Light: APEX 800 FS-DC at 810W The Dutch Lighting APEX 800 FS-DC LED is a commercial greenhouse LED grow. Light pulling 810W typical (up to 1050W max) on a 208-400V DC driver. PPF lands at 2100 µmol/s with photon efficacy of 2.6 µmol/J across the OSRAM LED full spectrum toplight build. The fixture replaces 1000W DE HPS 1:1 in greenhouse bays and high-bay rooms. A 120-140 degree beam angle distributes photons across tall greenhouse hang heights. Power factor stays above 0.98 on commercial circuits, current draw runs 2.6A at 400V or 3.9A at 208V. The fixture earns IP65 for damp greenhouse environments. 1000W HPS Replacement LED Toplight with Venturi Passive Cooling Growers typically hang the toplight 4 to 6 ft above canopy in greenhouse bays. And ramp from 30 percent through transition up to full intensity in peak bloom. Dimming runs 30 to 100 percent on 0-10V control for staged photoperiod ramps. The Venturi passive cooling LED fixture design eliminates fans, dropping moving parts and noise in commercial greenhouses. Build covers 5 years of warranty and L90 lifetime over 50,000 hours for multi-cycle commercial operations. The high voltage 208-400V grow light input fits commercial 277V single-phase and 400V three-phase rooms common in industrial cultivation buildouts. DLC certified 800W LED for cultivation rebate paperwork in qualifying utility programs. Build quality holds up across multi-cycle commercial deployments. Per-fixture amp draw matters when sizing a high-density bloom panel. Spectrum consistency across fixture batches keeps cultivar response repeatable. Stage-specific ramps reduce light stress during transition between veg and bloom. Field-replaceable drivers shorten downtime when service intervals come due. Key Features Power and Output: 810W typical input delivers 2100 µmol/s PPF at 2.6 µmol/J fixture efficacy. OSRAM Diodes: Full spectrum FS-DC profile uses OSRAM LEDs for stable photon delivery. High Voltage Range: 208-400V auto-sensing input fits 277V single-phase and 400V three-phase commercial rooms. Beam Angle: 120-140 degree spread distributes light across tall greenhouse hang heights. Venturi Passive Cooling: Fanless heatsink design eliminates moving parts in humid greenhouse environments. IP65 Rated Build: Sealed enclosure handles damp greenhouse air and wash-down cleaning between cycles. Dimming: 30-100% dimmable for staged ramps from transition through peak bloom. Power Factor: >0.98 PF keeps utility billing honest in dense commercial deployments. L90 Lifetime: Over 50,000 hours of L90 light maintenance for multi-cycle commercial flower rooms. Warranty: 5-year warranty for multi-cycle commercial cultivation operations.
