OT02 Series — Airport Apron & Taxiway Lighting
Gen 2 LED with 191 lm/W peak efficacy, DIP switch wattage + CCT — purpose-built for mid-pole apron, taxiway service roads, and airport perimeter applications.
The OT02 Series (Gen 2) brings 191 lm/W peak efficacy and DIP switch selectable CCT (3000K/4000K/5000K) to airport lighting — a significant upgrade over Gen 1 for mid-pole applications on aprons, taxiway service roads, GSE staging areas, and security perimeters. With 9 DIP-selectable wattages from 48W to 300W (expandable to 800W), a single SKU covers most airport zones from 25ft to 60ft pole heights. Honest positioning: For 100ft+ high-mast installations exposed to extreme jet wash and weather, the OT Gen 1 with its IP66/IK10 rating remains the preferred choice. OT02 (IP65/IK09) is optimized for the vast majority of airport area lighting at mid-pole heights where higher efficacy, lower energy cost, and field-adjustable CCT deliver the best value.
Head-to-Head
OT02 (Gen 2) vs OT (Gen 1) — Honest Comparison
Both series achieve full cutoff U0 for FAA compliance. The choice depends on mounting height, exposure conditions, and whether field-adjustable CCT matters for your project.
| Specification | OT02 (Gen 2) | OT (Gen 1) | Advantage |
|---|---|---|---|
| Peak Efficacy | 191 lm/W | 163 lm/W | OT02 +17% |
| CCT Selection | DIP 3000K/4000K/5000K | Fixed at order | OT02 — field adjustable |
| DIP Wattage Steps | 9 levels (48W–300W) | Fixed wattage per model | OT02 — 1 SKU, many outputs |
| Wattage Range | 48W–300W (→800W) | 75W–800W | Gen 1 — higher max today |
| IP Rating | IP65 | IP66 | Gen 1 — jet water rated |
| IK Rating | IK09 | IK10 | Gen 1 — max impact |
| Surge Protection | 20kV/10kA | 20kV | Comparable |
| Uplight (BUG U) | U0 ✓ | U0 ✓ | Both FAA compliant |
| Ideal Mounting | 25–60ft mid-pole | 60–120ft high-mast | Different sweet spots |
Bottom line: OT02 delivers better efficacy and operational flexibility for the ~80% of airport area lighting mounted at 25–60ft. Gen 1 remains the go-to for extreme high-mast (100ft+) installations where IP66/IK10 protection against direct jet wash and maximum impact resistance are non-negotiable.

Common Airport Lighting Challenges
"We ordered 5000K for the cargo area but 4000K would have been better. Now I have 120 fixtures in the wrong color temp and no budget to reorder. If I could just flip a switch…"
— Electrical Contractor, regional cargo terminal
"Our taxiway service road poles are only 30ft, but we're using the same 420W fixtures as the apron high-masts. That's massive overkill — we're wasting energy and creating hot spots that blind the ground crews."
— Airport Facilities Manager, mid-size commercial airport
"We stock 8 different SKUs just to cover the various zones — apron, service road, parking, perimeter. Inventory management is a nightmare. I need fewer part numbers that can do more."
— Procurement Specialist, airport authority
"The energy manager says cut consumption 30%. The operations team says don't touch the light levels. I need fixtures that deliver the same lux at lower wattage — not dimming, actual higher efficacy."

⚠️ Critical: FAA Full Cutoff Mandatory Requirement
FAA regulations prohibit any upward light from apron luminaires. Full cutoff (0 candela at 90° and above) is a hard regulatory requirement to prevent glare hazards for pilots. The OT02 Series achieves BUG U0 across all 9 DIP wattage settings — 0.00 lm above the horizontal plane, verified by IES goniophotometer testing. No baffles, shields, or post-installation modifications required.
Configuration Guide
DIP Switch Guide — Airport Scenarios
Each OT02 fixture has two DIP switch banks: one for wattage (within its tier) and one for CCT (3000K/4000K/5000K). Adjustable in the field without tools — flip the switch, power cycle, done.
✈️
Apron: 300W Tier → 240W, 4000K
For 40ft poles at 2 per gate, set DIP to 240W for uniform 20+ fc coverage. Select 4000K for optimal FOD detection and CCTV performance. If design review shows excess fc, drop to 200W without hardware changes.
📦
Cargo Dock: 300W Tier → 300W, 5000K
Maximum lumen output (51,636 lm) at 5000K for detailed cargo inspection work. Achieves 30+ fc at 40ft pole height with Type IV optics for wall-wash coverage on loading dock faces.
🚗
Service Road: 80W Tier → 48W, 4000K
Taxiway service roads only need 1–2 fc. The 48W setting at 191 lm/W delivers 9,222 lm — more than enough at 25ft pole height with 150ft spacing. Lowest energy consumption in the lineup.
🔒
Security Perimeter: 80W Tier → 65W, 4000K
Perimeter fence lighting for CCTV effectiveness. The 65W setting delivers 12,413 lm — achieving 2+ fc minimum with excellent uniformity at 25ft height, 200ft spacing.
🅿️
Employee Parking: 140W Tier → 100W, 4000K
Staff parking lots need 5–10 fc per IES RP-20. The 100W DIP (18,313 lm) at 25–30ft height covers standard parking lot spacing. If future expansion adds rows, bump to 140W — same fixture.
🏢
Terminal Curbside: 140W Tier → 140W, 3000K
Passenger-facing areas benefit from warmer 3000K CCT. The 140W setting (24,761 lm) meets 10 fc curbside requirements at 30ft height. Warmer tone complements terminal architecture.
Why DIP Switch Matters at Airports
Airport projects often span 6–18 months from spec to installation. Design assumptions change — FAA review may require different illuminance levels, pole locations shift during construction, or a zone gets repurposed. With DIP wattage + CCT, you commit to hardware early but finalize output settings during commissioning. No reorders, no project delays, no change orders for wrong CCT.
Optics
Optics Analysis — Type III / IV / V for Airport Zones
Type IV — Wide Asymmetric (Primary Airport Optic)
The T401 Type IV optic is the primary distribution for OT02 airport applications. It delivers a wide asymmetric pattern — strong forward throw with controlled lateral spread — ideal for pole-mounted fixtures illuminating apron areas, cargo docks, and parking lots where light needs to reach forward without spilling backward over fences or into flight paths. Verified by IES file data across all 9 DIP wattages.
Best for: Apron perimeters, cargo loading docks, terminal curbsides, security perimeters — any area where one-sided throw from a boundary pole is needed.
Type V — Symmetric (Center Coverage)
Type V provides 360° symmetric distribution for center-mounted poles in open areas. At airports, this is used for apron center poles where light needs to spread equally in all directions — GSE staging areas, employee parking lot interiors, and mid-field apron poles.
Best for: Center-of-area poles in parking lots, GSE staging, and open apron areas where 360° coverage is needed from each pole.
Type III — Forward Throw (Roadway Pattern)
Type III delivers a medium forward-throw pattern optimized for roadway and linear applications. At airports, this covers taxiway service roads, access roads, and perimeter patrol roads where light is needed in a rectangular pattern along the road centerline.
Best for: Taxiway service roads, airport access roads, perimeter patrol roads, and any linear pathway requiring uniform coverage between poles.
All three optic types maintain BUG U0 (zero uplight) — FAA full cutoff is built into the optic and housing design, not dependent on optic selection.
ROI
Energy & Cost Comparison — 400W HPS vs OT02 200W
Typical mid-pole airport retrofit scenario: replacing 400W HPS on 30–40ft poles with OT02 200W — a common upgrade for apron perimeters, service roads, and parking areas.
| Metric | 400W HPS | OT02 200W | Savings |
|---|---|---|---|
| System wattage (fixture + ballast) | 460W | 200W | 57% reduction |
| System output | ~50,000 lm initial (degrades 40% by mid-life) | 36,805 lm (L90 at 100,000 hrs) | LED maintains output; HPS does not |
| System efficacy | ~109 lm/W (initial, pre-depreciation) | 182 lm/W (IES verified) | +67% more efficient |
| Annual energy per fixture (dusk-to-dawn) | 1,898 kWh | 826 kWh | 1,072 kWh/fixture |
| 200 fixtures (site-wide mid-pole) | $56,940/year | $24,780/year | $32,160/year savings |
| Lamp replacement (HPS every 24,000 hrs) | $60–80/fixture every 5.8 years | $0 for 10+ years | $12,000–16,000 per cycle saved |
| DLC utility rebate (OT02) | — | $100–200/fixture | $20,000–40,000 total rebate |
| Simple payback (with DLC rebate + AIP grant) | — | — | < 2.5 years |
Energy cost at US commercial average $0.15/kWh. Dusk-to-dawn operation ≈ 4,130 hrs/year. HPS system wattage includes ballast loss (~15%). FAA/DOT Airport Improvement Program grants cover 60–90% of eligible upgrade costs for public-use airports.
Bottom line: OT02 200W replaces 400W HPS with 57% less energy, 67% higher efficacy, and zero lamp maintenance — while adding DIP CCT flexibility. For airports with FAA/DOT grant funding, payback is under 2.5 years on energy savings alone.

| Employee Parking | 80W or 100W | 4000K | 1/pole | 25–30ft | Type V | 5–10 fc |
Single SKU Strategy: OT02 300W Tier Covers Most Zones
The OT02 300W tier (DIP: 240W/300W) paired with the 80W tier (DIP: 48W/65W/80W) covers every airport zone listed above with just two SKUs. The 300W tier handles high-output apron and cargo needs (DIP down to 240W for margin), while the 80W tier covers service roads, perimeter, and parking (DIP to exact level needed). Add the 140W tier for terminal curbside applications if required. Three SKUs replace what traditionally required 8+ different fixture models.

FAQ
Frequently Asked Questions
What makes the OT02 Series different from the OT Gen 1 for airport lighting?
The OT02 Series (Gen 2) delivers up to 191 lm/W peak efficacy — roughly 17% higher than Gen 1's ~163 lm/W — and adds DIP switch selectable CCT (3000K/4000K/5000K) alongside DIP wattage selection. This means a single SKU covers multiple airport zones with field-adjustable output and color temperature. However, Gen 1 retains IP66/IK10 ratings vs OT02's IP65/IK09, so for extreme-exposure high-mast installations above 100ft, Gen 1 remains the preferred choice. OT02 excels at mid-pole (25–60ft) apron, taxiway, and service road applications.
Can OT02 meet FAA AC 150/5345 full cutoff requirements?
Yes. The OT02 Series achieves BUG U0 rating — physically zero uplight verified by IES testing (0.00 lm in the 90–180° zone across all 9 DIP wattage settings). This meets the FAA mandatory full cutoff requirement for all apron and ramp luminaires, preventing glare hazards for pilots on approach, departure, and ground taxi.
How does DIP switch CCT selection benefit airport installations?
Airport zones have different CCT preferences: 4000K neutral white is standard for aprons (best for FOD detection and CCTV), 5000K for cargo work areas (maximum visual acuity for detailed inspection), and 3000K for passenger terminal curbsides (warmer, more comfortable for passengers). With OT02's DIP CCT, one SKU shipped to site can be configured per zone during installation — eliminating reorder delays and reducing inventory to a single part number.
What wattage range is available and how does expansion work?
The OT02 currently ships in four DIP tiers: 80W (48/65/80W), 140W (100/140W), 200W (165/200W), and 300W (240/300W) — that's 9 selectable wattages from one product line. The platform is designed to expand to 400W, 500W, 600W, 700W, and 800W tiers using the same housing and optic architecture, enabling future high-mast applications as higher-wattage tiers become available.
What is the ROI for replacing HPS/MH with OT02 at an airport?
For a mid-size airport replacing 200 × 400W HPS fixtures on 25–40ft poles with OT02 200W: annual electricity drops from ~$105,000 to ~$52,000 — saving $53,000/year. With DLC utility rebates ($100–200/fixture) and FAA/DOT AIP grants covering 60–90%, payback is typically under 2.5 years. Maintenance savings add $2,000–4,000 per service event eliminated, with LED removing lamp/ballast replacements for 10+ years.
