OT02 Series — Tennis Court Lighting
Field-selectable CCT and wattage in one fixture — 5000K for competition, 4000K for club play, 3000K for residential courts. 48–300W DIP switch range at up to 191 lm/W.
The OT02 Series (Gen 2) is Auvolar's next-generation LED area light designed for tennis court applications requiring field-adjustable color temperature and wattage. Unlike Gen 1 which offers fixed CCT, OT02 features DIP switch selectable CCT (3000K/4000K/5000K) — a game-changer for tennis facilities serving multiple user groups. The same fixture illuminates a USTA competition court at 5000K daylight white for maximum ball tracking, then switches to 3000K warm white on a residential neighborhood court to satisfy dark sky and HOA requirements. With 9 DIP wattage settings from 48W to 300W and peak efficacy of 191 lm/W (IES verified), OT02 delivers 15–20% more lumens per watt than OT Gen 1 while covering every court class from Class IV recreational to Class II tournament with a single product family.

What We Hear
Common Tennis Court Lighting Challenges
"We host USTA league matches at night and recreational clinics in the evening. The league players want bright, daylight-white light for competition — but clinic members say it feels like a hospital. We can't please both groups with one fixed CCT."
— Club Manager, 8-court tennis facility, Scottsdale AZ
"The HOA board voted to shut down evening tennis because neighbors complained the 5000K lights were too harsh and cold. If we could have installed warm white from the start, we'd still have our courts lit."
— HOA President, residential community, Orange County CA
"We need 75 fc for our regional tournament courts but only 30 fc for the practice courts. The old system uses the same 1000W metal halide everywhere — practice courts are over-lit and wasting $8,000/year in electricity."
— Tournament Director, 12-court public facility, Sacramento CA
"I quoted the job with 300W fixtures, then the owner decided they wanted Class III instead of Class IV. Now I need to re-order higher wattage. If I could just flip a DIP switch on-site, I'd save two weeks and $3,000 in change orders."

Why Vertical Illuminance Matters for Tennis
Tennis is uniquely demanding for vertical illuminance. Players track a ball moving through 3D space at speeds up to 130 mph — a ball at 10–15 ft height during a lob must be visible against the night sky. Poor vertical illuminance creates a "dark zone" where the ball disappears mid-flight. IES RP-6 requires vertical footcandles measured at 5 ft height throughout the court area, and USTA recommends vertical fc be at least 60% of horizontal fc for competitive play.
Field Configuration
DIP Switch Guide — Tennis-Specific Scenarios
OT02's dual DIP switch system lets electricians configure both wattage and CCT on-site — no factory reorders, no inventory of multiple SKUs. Here's how to set each for different tennis court scenarios:
🏆 Competition Court (USTA/ITF League)
Class III – 50 fcWattage DIP
200W–300W
4 × 300W = 206,544 lm → ~55 fc avg on 7,200 ft² court
CCT DIP
5000K (Daylight White)
Maximum contrast: yellow ball pops against green/blue court
🎾 Recreational Club Court
Class III-IV – 30-50 fcWattage DIP
165W–200W
4 × 200W = 147,220 lm → ~40 fc avg — comfortable for social play
CCT DIP

Optical Design
Optics Selection — Type III vs Type IV for Tennis
Unlike OT Gen 1 which primarily uses Type V symmetric, OT02 offers Type III, Type IV, and Type V optics — enabling optimized distribution based on pole position relative to the court.
Type III — Sideline Poles
Forward throw: 2.75 × mounting height
Lateral spread: 1.0 × mounting height
Best for: Poles positioned along the sideline (5–8 ft outside the court edge). Type III pushes light forward across the court width while limiting backlight behind the pole. This is the primary optic for 4-pole configurations where each pole serves one quadrant of the court.
IES file: AOK-[W]WOT02-NVS-L2 (Type III distribution)
Type IV — Corner Poles
Forward throw: 2.75 × mounting height
Lateral spread: negligible behind pole
Best for: Corner pole positions where the fixture must throw light diagonally across the court while producing near-zero backlight toward adjacent properties. Type IV's semicircular distribution concentrates all light forward — critical for residential-adjacent courts.
IES file: AOK-[W]WOT02-NVS-T401 (Type IV distribution)
Recommended Optic Mix — 4-Pole Single Court
Type III
Pole 1 (sideline NW)
Aim: toward court center
Type IV
Pole 2 (corner NE)
Aim: diagonal across court
Type III
Pole 3 (sideline SE)
Aim: toward court center
Type IV
Pole 4 (corner SW)
Aim: diagonal across court
Mix optics for best uniformity. Type III on sideline poles for broad court coverage; Type IV on corner poles for controlled forward throw with zero backlight toward neighbors.
ROI
Energy & Cost Savings — OT02 300W vs 1000W Metal Halide
| Metric | 1000W Metal Halide | OT02 300W LED | Savings |
|---|---|---|---|
| System wattage (actual) | 1,080W (incl. ballast) | 300W (IES verified) | 72% reduction |

| Annual kWh — 4 courts, 8 poles each, 12 hr/wk | 21,557 kWh | 5,990 kWh | 15,567 kWh saved |
| Annual electricity cost ($0.15/kWh) | $3,234 | $899 | $2,335/year per court |
| MH lamp replacement (every 2 yrs, 8 fixtures) | $1,200/yr amortized per court | $0 | $1,200/yr per court |
| Total annual savings — per court | — | — | ~$3,535/year |
| Total annual savings — 4-court facility | — | — | ~$14,140/year |
Calculation: 8 poles per court × 12 hr/week × 52 weeks = 624 hr/yr per fixture. MH ballast loss = 8%. MH lamp cost = $300/fixture, 2-year life. US commercial avg $0.15/kWh.
Payback period: OT02 300W fixtures at ~$400–600 each × 8 per court = $3,200–4,800. With DLC utility rebates of $100–200/fixture ($800–1,600 per court), net fixture cost is recovered in 6–12 months from electricity savings alone. Installation cost is comparable to MH replacement since existing poles and wiring are reused.

Frequently Asked Questions
OT02 Tennis Court Lighting FAQ
Q: What makes OT02 Series better than OT Gen 1 for tennis courts?
OT02 (Gen 2) adds DIP switch CCT selection (3000K/4000K/5000K) alongside DIP wattage selection — letting you field-adjust color temperature per court use case. Competition courts get 5000K for maximum ball visibility, recreational clubs get 4000K for balanced contrast, and residential neighborhood courts get 3000K to minimize neighbor complaints. OT02 also delivers 191 lm/W peak efficacy vs Gen 1's 163 lm/W, meaning 15–20% more light per watt.
Q: How many OT02 fixtures do I need for a single tennis court?
A standard single court (60 × 120 ft) typically needs 4 poles with one OT02 fixture per pole. For Class IV recreational (30 fc target), use OT02 200W (36,805 lm each) on 25–30 ft poles. For Class III club competition (50 fc target), use OT02 300W (51,636 lm each) on 30–35 ft poles. DIP switch lets you fine-tune wattage on-site — install OT02 300W and DIP down to 240W if light levels exceed target.
Q: Can I change the CCT after installation without replacing the fixture?
Yes — that's the OT02's key advantage. A DIP switch inside the driver compartment lets you select 3000K, 4000K, or 5000K in the field. If a residential HOA complains about "too white" light, your electrician switches from 5000K to 3000K in 5 minutes per fixture without ordering new luminaires. No rewiring, no relamping, no crane rental for fixture swaps.
Q: What CCT should I choose for competitive vs recreational tennis?
5000K (daylight white) is recommended for USTA/ITF competition courts — it maximizes contrast between the yellow ball and green/blue court surface, and provides the most accurate color rendering for players and officials. 4000K (neutral white) is the most popular for club and recreational play — good ball visibility with a more comfortable, less clinical feel. 3000K (warm white) is ideal for residential neighborhood courts where reducing light "harshness" and neighbor impact matters more than competitive performance.
Q: How does OT02 IP65/IK09 compare to OT Gen 1 IP66/IK10 for outdoor tennis courts?
IP65 means full dust protection and protection against water jets from any direction — more than adequate for outdoor tennis court installations exposed to rain, sprinklers, and hose-down cleaning. The difference from IP66 (powerful water jets) is irrelevant for pole-mounted luminaires at 25–40 ft height. IK09 handles 10-joule impacts (equivalent to a 5 kg mass dropped from 200mm); IK10 handles 20-joule. Both far exceed any realistic impact risk for pole-mounted sports lighting.
