Flex CH2 Series LED High Bay

Engineered by Flex Lighting Solutions, now a Linmore LED brand.

The Flex CH2 Series is a range of compact LED high bay fixtures with features customers value the most: quality, reliability, and performance in a cost-effective design. These Compact LED High Bays take the award-winning technology from the Essentials Series and puts it into a more value-centered platform.

Models available with 2, 4, 6 and 8 LED modules to deliver a lumen range from 6,000 to 37,000 lumens, up to 173 lumens per watt and an ultra-long life up to 180,000 hours (L70 via TM-21).

Applications: industrial and manufacturing facilities, warehouses, distribution centers, hangars and indoor sports.

  • Extruded Aluminum Heat Sinks: provide optimal thermal management by decreasing LED junction temperature, ensuring longer life and higher efficacy. LED boards attached to the heat sink using a high quality thermally conductive adhesive rather than screws or rivets. This ensures good contact between PCB and heat sinks for excellent thermal conductivity.
  • LED Boards: FR4 PCB is used to limit stress on solder joints by matching coefficient of thermal expansion between the LED and the PCB more closely.
  • Power Supply Access: Wireway cover allows easy access and quick wiring. Hole accepting 3/4” stem (not centered) and also 1/2” KO near top end of wire way. If center stem mount is required, select STEM in mounting options.
  • Wire Guards: Optional factory-installed wire guards for the fixture.
  • Power Input: 120-277V or 347-480 (50/60Hz), typical, depending on model.
  • Power Factor: Greater than 0.9 (0.96–0.99 typical).
  • Total Harmonic Distortion: Less than 20%, 10% typical.
  • Surge Protection: Standard is 6kV for drivers. Additional surge protection is available. All HV orders will have 10kV SRG automatically added (contact sales for questions).
  • Emergency Battery Backup (EMB and EMB2): EMB produces ~2700 lumens for a minimum of 90 minutes. EMB2 produces ~4300 lumens for a minimum of 90 minutes. EMB has 15 watts output, EMB2 has 25 watts output. Available in LV and HV (EMB only).
  • Environment: Dry/Damp, for interior applications (IP4X). Dust-resistant LED modules.
  • Ambient Range Operation: -40°C up to 45°C (-40°F up to 113°F).
  • CCT: 3500K, 4000K and 5000K standard, other CCT available (extended lead time).
  • CRI: 80+ standard, 85 typical.
  • Lenses: UV stable polycarbonate8 Clear, Aisle and Narrow or acrylic (PMMA) Frosted available.
  • Field-replaceable lenses: Clear, Frosted, Aisle, and Narrow.
  • Mounting: Fixture is cable ready (CRM). Other options are STEM (comes with a 3/4” opening in the center of the STEM box), HOOK and surface mount (with optional MBR). MBR reduces ambient range by 5°C when mounted flush to junction box.
  • Dimming: 0-10V standard. Dimming range 100% to 10%.
  • Avi-on Intelligent Controls: Bluetooth® advanced wireless controls available.
  • Lenses: UV stable polycarbonate8 Clear, Aisle and Narrow or acrylic (PMMA) Frosted available.
  • Occupancy and Dimming Occupancy Sensors: Optional – factory installed photocell sensors. IR-TEC and WattStopper standard, other options available upon request.
  • Standard: 5-year product warranty including 5 years of guaranteed light levels (L70). Optional 7 and 10-year extended product warranties available.
  • 10Y Premium Warranty: Optional 10-year warranty covering parts, light levels (L70) and $300 of labor per fixture.
  • Conforms to ETL listed (UL 1598:2018 Ed.4).
  • RoHS compliant.
  • EMI: Title 47 CFR 15 Class A and ICES-005.
  • CSA C22.2#250.0:2018 Ed.4.
