Application Guide — OT02 Series

Auto Dealership Lighting

191 lm/W IES-verified efficacy. DIP-selectable CCT and wattage. One SKU for every zone — front display rows to rear inventory lots.

191 lm/W Peak Efficacy →DIP CCT: 3K/4K/5K →Type IV Acuity-Level Distribution →

The OT02 Series was engineered to solve the two most expensive problems in auto dealership lighting: wasted energy and CCT mismatch. At 191 lm/W peak efficacy (IES file: AOK-80WoT02-NVS-L2, tested by EVERFINE GO-2000B goniophotometer), OT02 delivers more lumens per watt than any fixture in its class — meaning brighter vehicle displays at lower operating cost. The built-in DIP switch selects 3000K, 4000K, or 5000K CCT in the field, eliminating the most common dealership lighting return scenario: wrong CCT after install. A second DIP switch selects output wattage (48W–300W across 4 tiers), so one SKU covers both your high-intensity front display rows and lower-intensity rear inventory areas. All models deliver U0 zero uplight (verified across all 9 IES files) and Acuity/Lithonia-equivalent Type IV distribution — at a fraction of the Acuity price point.

What We Hear

Real Dealership Lighting Problems — OT02 Solves Them

“We installed 5000K fixtures and the BMW store manager said it was too cold — he wanted 4000K. Had to return 40 fixtures and reorder. Cost us 6 weeks and a lot of credibility.”

— General Manager, auto group, Southern California  → OT02 DIP CCT: switch 5000K → 4000K in 2 min per fixture

“Front display rows need 300W for max brightness. Rear inventory rows only need 150W — we had to order two different SKUs, and the supplier shipped the wrong ratio. The project got delayed three weeks.”

— Operations Director, 5-location dealer group, Texas  → OT02 DIP wattage: 300W front, 165W rear — one SKU, zero confusion

“Acuity quoted us $800 per fixture for a 40-lot upgrade. That's $32,000 just in fixtures before install. We can't justify that to corporate — but they also won't accept a cheap-looking spec.”

— Procurement Manager, national franchise group, Midwest  → OT02 delivers equivalent Type IV distribution at a fraction of Acuity pricing

“40 lights, monthly electricity bill is $6,000. The board asked us to cut 30% from facilities costs this quarter. Lighting is the obvious lever but we haven't moved yet.”

— CFO, multi-brand dealership group, Southeast  → OT02 191 lm/W: same light output at 28% of MH wattage → save $4,300+/month

📊 Why 191 lm/W Matters for Dealerships

At 191 lm/W (48W setting), OT02 delivers 17% more lumens per watt than OT Gen 1's best (163 lm/W) and 30%+ more than most competitor 300W shoebox lights (industry average ~140–150 lm/W). For a 40-fixture dealership this means: same illuminance level at significantly lower wattage — or meaningfully higher illuminance at the same cost. The front display row, where every extra footcandle translates to more visible vehicles from the road, benefits most from this efficacy advantage.

⚡ Vertical Illuminance — The Metric That Sells Cars

Auto dealerships need high vertical illuminance because vehicles are vertical surfaces — hood, doors, and front fascia face customers at eye level. IES DG-19 recommends vertical illuminance ≥ 50% of horizontal at 3.5 ft height. Mounting poles too high (above 30 ft) reduces vertical illuminance significantly. OT02's Type IV (T401) distribution is optimized for 25 ft mounting height — maximizing both coverage and vertical surface illumination simultaneously.

Field Configuration

DIP Switch Configuration Guide

OT02 has two DIP switch banks — one for wattage (output level), one for CCT. Both are accessible without special tools after opening the driver compartment cover.

🌡️ CCT DIP Switch

5000K

Most common for dealerships. Makes white vehicles appear crisp, enhances metallic paint sparkle. Best visual acuity for color comparison.

Volume brands

4000K

Neutral white. Preferred by luxury brands (BMW, Mercedes, Lexus) for warm-premium ambiance without sacrificing brightness.

Luxury brands

3000K

Warm white. Not recommended for vehicle display lots — imparts a yellow cast that misrepresents paint colors. Use for accent or entrance areas only.

Accent/entrance only

CCT can be changed after installation. Power fixture off before switching. Setting takes effect on next power-on cycle.

💡 Dealership Tip: Set 5000K as Default, Keep 4000K Option Open

Order all fixtures set to 5000K (factory default for most volume brand dealerships). If a brand rebranding or luxury brand acquisition requires 4000K across a lot, your electrician can switch all fixtures in a single afternoon visit — no reorder, no downtime beyond the switch procedure. Document the DIP settings in your maintenance log for each pole.

Design Guide

Auto Dealership Lighting Design Principles

🌡️ CCT Strategy: 5000K for Display, 4000K for Luxury

5000K is the industry standard for new car display lots — it maximizes perceived brightness, makes white and silver vehicles appear crisp, and enhances metallic paint sparkle. 4000K is preferred by BMW, Mercedes-Benz, Lexus, and Audi for an upscale, warm-neutral ambiance. With OT02 DIP CCT, you can use one fixture spec for both brand types and adjust in the field. Avoid 3000K in display zones — it misrepresents paint colors and can cause color-match disputes at delivery.

Front High-Power + Rear Low-Power = One SKU

Traditional dealership specs require two SKUs: 300W for front display rows, 150W for rear inventory. OT02 eliminates this with DIP wattage selection. Order all OT02 300W-tier fixtures, set front rows to 300W (or 240W) and rear inventory rows to 165W via DIP switch. Benefits: one SKU on the PO, one product on the truck, one training session for the install crew, and no wrong-model delivery risk.

📐 Maximize Vertical Illuminance — The Metric That Closes Sales

Vehicle buyers compare paint color and body condition at night. Both require high vertical illuminance — the amount of light striking the vertical surfaces of the car at eye level. IES DG-19 recommends vertical illuminance ≥ 50% of horizontal illuminance at 3.5 ft height. Achieve this by keeping pole height at 25–30 ft (not 35 ft), using Type IV optics (forward-wide throw, not narrow spot), and maintaining ≤ 65 ft pole spacing in the front display row.

🏗️ Pole Height 25 ft — The Dealership Optimum

25 ft mounting height is the sweet spot for dealership display lots: it delivers the best vertical illuminance delivery (critical for vehicle surface illumination), achieves 50–60 ft coverage radius with OT02 300W, and keeps the fixture footprint within typical urban setback limits. At 30 ft, coverage area increases but vertical illuminance drops ~25% — acceptable for rear inventory rows. At 35 ft, vertical illuminance is inadequate for front display zones.

🛣️ Front Row Pole Density Attracts Street Traffic

The front display row facing the street is your primary off-hour marketing channel. Dense, bright front-row lighting creates the "wall of cars" effect visible from 500+ ft that pulls passing traffic into the lot. Spec tighter spacing (50–60 ft between poles) with OT02 300W and Type IV optics angled toward the street. Behind the front row, use 65–75 ft spacing with 200W setting — adequate for browsing without the premium energy spend of the display zone.

🔧 Uniformity: 3:1 Max:Min for Display Zones

Poor uniformity creates visible bright-spot / dark-gap patterns across the lot. Customers perceive dimly-lit vehicles as lower quality — a direct impact on close rates for vehicles unlucky enough to sit in a dark gap. IES RP-33 requires 3:1 max:min uniformity for display lots. Achieve this with consistent OT02 wattage settings across a zone, consistent pole spacing (no more than 2.5× mounting height), and uniform optic selection (all Type IV in the same zone row).

Why One SKU Works for All Zones

Traditional dealership specs require 2–3 separate SKUs for different lot zones. OT02's DIP switch wattage selection eliminates this: purchase the 300W tier across the entire project, then configure each fixture at install time. Front display rows → 300W. Middle aisles → 200W. Rear inventory → 165W. Service drive → 140W. One purchase order, one delivery, one install crew learning one product. The wiring and mounting brackets are identical across all settings — only the DIP switch position changes.

Frequently Asked Questions

OT02 Auto Dealership Lighting FAQ

Q: Can I change the color temperature of OT02 lights after installation if my brand standard changes?

Yes. The OT02 Series features a DIP switch on the driver that lets you select 3000K, 4000K, or 5000K in the field — no rewiring, no replacement. If you install 5000K and a new brand manager requests 4000K, flip the switch. This eliminates the most common source of dealership lighting returns: CCT mismatches after install. The switch is accessible after removing the cover, and the change takes under 2 minutes per fixture.

Q: Can one OT02 fixture handle both 300W front display and 150W rear inventory zones?

Yes. The OT02 300W tier (240W/300W DIP selectable) covers front display rows. Set the same fixture to 165W or 200W (via DIP switch) for rear inventory areas. One SKU purchase, one install crew, zero SKU confusion on the order. This eliminates split orders, separate SKUs in inventory, and the risk of receiving the wrong wattage on a large project.

Q: How does OT02 compare to Acuity/Lithonia area lights for dealership use?

OT02 delivers Acuity-level Type IV optical distribution (IES file: AOK-300WOT02-NVS-L2-T401) at significantly lower cost. Acuity Lithonia DSX1 LED 300W lists at $600–900 per fixture; OT02 delivers comparable lm/W, comparable BUG rating, and DIP-selectable CCT (which Acuity does not offer at this price point). For dealerships needing 30–50 fixtures, the per-unit delta alone funds a photometric design + commissioning budget.

Q: What is the monthly electricity saving for a 40-fixture dealership upgrading to OT02 from 1000W metal halide?

A 1000W metal halide system draws ~1,080W including ballast. OT02 300W draws 300W. Across 40 fixtures running 12 hrs/day at $0.15/kWh: MH costs ~$9,460/month; OT02 costs ~$2,627/month — saving approximately $6,833/month or $82,000/year. The OT02's 191 lm/W peak efficacy (vs OT Gen 1's 163 lm/W) provides an additional 17% savings versus a Gen 1 upgrade path.

Q: What color temperature should I specify for a luxury brand auto dealership?

4000K is the preferred choice for luxury brands (BMW, Mercedes-Benz, Lexus, Audi) — it provides a warm-neutral ambiance that aligns with premium interior aesthetics while still delivering high vertical illuminance for vehicle display. 5000K is best for volume brands (Toyota, Honda, Chevy) where crisp white light maximizes visual acuity for color comparison. The OT02 DIP switch supports both — specify 5000K as default, with 4000K available per zone or per brand rebranding events.
