OT02 — Industrial Site Lighting
DIP switch–selectable 48W–300W. One fixture SKU covers every zone: security fence, service road, loading dock, and active work area — at 191 lm/W peak efficacy.
Industrial sites governed by IES RP-7-17 and OSHA 29 CFR 1926.56 require vastly different illuminance levels across zones — from 1 fc at security fencing to 20 fc at active work areas. Conventional solutions demand separate SKUs for each wattage, multiplying procurement complexity and inventory cost. The OT02 Series solves this with a single DIP switch–selectable fixture delivering 48W to 300W in the field, covering all mid-pole zones (20–40ft) at 172–191 lm/W efficacy. For high-mast poles (60ft+) requiring 420W–800W, the OT Gen 1 is the right choice — OT02 and OT Gen 1 are designed to work together on the same industrial campus.

💡 Recommended pairing: Use OT02 on perimeter fences (48W–80W), service roads (100W), loading docks (200W), and work areas (300W) — all on 20–40ft poles. Use OT Gen 1 420W–800W for open yard coverage on 60ft+ high-mast poles. Both are U0, both are DLC qualified — they share the same design philosophy at different scales.
What We Hear
Industrial Site Lighting Pain Points
"Fence perimeter lighting only needs about 50W, but major brands don't make a 50W area light. The smallest they sell is 150W. We were burning 3× the power we needed for every fence pole — 80 poles around the facility."
— Facilities Manager, chemical processing plant, Houston TX→ OT02 fix: Set DIP to 48W (9,222 lm, 191 lm/W) — purpose-built for perimeter fencing on 20–25ft poles. Exactly the right output, not 3× it.
"We lit the loading dock at 150W, then found out after installation that OSHA requires 10 fc and we were hitting 6 fc. Upgrading to 250W fixtures after everything was wired in cost us over $5,000 in rework — new fixtures, new conduit runs, electrician time."
— Safety Director, regional distribution center, Columbus OH→ OT02 fix: Install at 165W, verify illuminance with a light meter. Under-spec? Flip DIP switch to 200W on-site. No rewiring, no rework, no rescheduling electricians.
"We have four lighting zones: fence, road, dock, and work floor exit. Four zones, four wattages, four different SKUs — each manufacturer has a 20-unit minimum order. We have 80 units of each sitting in the warehouse, half of which we'll never use because we over-ordered to hit MOQ."
— Procurement Manager, auto parts manufacturer, Detroit MI→ OT02 fix: One SKU covers all four zones. Order what you need — no MOQ pressure from multi-SKU minimums, no dead inventory.
"Our industrial electric rate is $0.20/kWh — double the commercial average. Every watt we waste over what's actually needed costs us real money 24/7. I need fixtures that are precisely matched to each zone, not over-specified because that's what's available off the shelf."
— Energy Manager, large distribution facility, Phoenix AZ→ OT02 fix: 191 lm/W at 48W, 182 lm/W at 100W, 185 lm/W at 165W — every DIP setting is dialed precisely to what each zone needs, not rounded up to the nearest available fixed wattage.

Energy Savings — OT02 vs HPS (Industrial Rate $0.20/kWh)
| Metric | 250W HPS (400W system) | OT02 165W DIP | Savings |
|---|---|---|---|
| System wattage (incl. ballast) | 430W | 165W | 62% reduction |

| Total savings per fixture/year | — | — | $318/fixture/year |
| 50-fixture site annual savings | — | — | $15,900/year |
HPS system wattage includes ~8% ballast loss. Industrial electricity at $0.20/kWh (US industrial average 2024). HPS lamp-only rated 24,000 hr (initial lumens stated; mean lumens ~15,000 after depreciation). OT02 L90 lifespan 50,000+ hr at operating temp. Payback calculation excludes DLC utility rebates ($100–200/fixture).
Precision Matching = Bigger Savings Than You Think
The DIP switch advantage isn't just convenience — it's a direct energy cost reduction. When fence poles only need 48W but the smallest available fixture is 150W, you're paying for 102W of wasted electricity on every pole, every hour of operation. At $0.20/kWh × 12 hr/day × 365 days × 80 fence poles, that's $7,159/year in waste from oversized fence fixtures alone. DIP selection eliminates that waste by matching power output precisely to zone requirements.
DLC rebates: $100–200/fixture at most US utilities. A 50-fixture site qualifies for $5,000–10,000 in rebates, reducing payback to under 12 months at $0.20/kWh industrial rates.

Common Questions
OT02 Industrial Site Lighting FAQ
Q: What wattage should I select for loading dock lighting with OT02?
A: IES RP-7-17 requires 10 fc horizontal and 5 fc vertical at loading docks. For a standard 40×80ft loading dock at 25–30ft mounting height, OT02 200W (165/200W DIP tier, 36,805 lm) with Type IV optics delivers 12–18 fc and meets the 3:1 uniformity requirement. If the dock is narrower or has lower ceiling height, the 140W tier (100/140W DIP, 24,761 lm) is often sufficient — saving $0.20/hr in electricity per fixture at $0.20/kWh industrial rates.
Q: Can OT02 be used on 60ft or taller high-mast poles?
A: No — OT02 tops out at 300W / 51,636 lm, which is appropriate for mid-poles in the 20–40ft range. At 60ft mounting height, you need 420W–800W output to achieve IES RP-7-17 target illuminance levels across large industrial yards. For high-mast applications (60–100ft poles), use OT Gen 1 (420W, 600W, or 800W). OT02 and OT Gen 1 are complementary: OT02 handles perimeter fences and loading docks; OT Gen 1 handles open storage yards on tall poles.
Q: How does DIP switch wattage selection reduce procurement complexity?
A: A typical industrial site has four distinct illuminance zones: security fence (≈50W needed), service road (≈100W), loading dock (≈200W), and active work area (≈300W). Without DIP selection, you order four separate SKUs — each with its own minimum order quantity, lead time, and inventory slot. OT02 ships as a single part number; electricians set wattage in the field via DIP switch before mounting. One purchase order, one SKU, one inventory bin — any spare can cover any zone.
Q: What is the ROI compared to HPS fixtures for industrial yard lighting?
A: OT02 200W replaces a 400W HPS fixture (450W system with ballast loss). Annual savings per fixture: 260W × 4,380 hr (12 hr/day) × $0.20/kWh = $228/fixture/year. At typical industrial pricing of $350–450 per OT02 fixture plus $100–200 DLC rebate, simple payback is 12–18 months. Versus 1000W HPS on mid-poles, OT02 300W saves $580/fixture/year in electricity alone.
Q: Does OT02 meet OSHA 29 CFR 1926.56 minimum lighting requirements?
A: Yes. OSHA 29 CFR 1926.56 requires 5 fc for general construction/warehouse areas and 3 fc for general site areas. OT02 at any DIP setting from 100W upward on 25–30ft poles delivers well above OSHA minimums at standard pole spacing. Even the 48W setting (9,222 lm) on a 20ft perimeter pole at 80ft spacing achieves 1–2 fc — meeting the 1 fc security perimeter standard per IES RP-7-17.
