UT-50 Series Works
1. Scalable Output — One Series, Many Roles
The UT-50 family covers small-scale accent lighting (30W) up to large-area illumination (400W). This scalability allows specifiers to standardize on one chassis and optical system across a project while matching wattage to need — simplifying procurement, spare parts, and visual consistency.
2. High Efficacy & Brightness Consistency
With 100–110 lm/W, these fixtures deliver impressive lumen output per watt. That means brighter illumination with lower energy draw — ideal for commercial exteriors, façade washing, parking areas, and landscape lighting.
3. DOB (Driver on Board) Simplicity & Reliability
The UT-50-067 models use DOB drivers (Driver On Board), which reduce component complexity and size, improve thermal coupling, and often lower failure points compared with separate external drivers. DOB designs support a compact profile and are optimized for long-term, continuous outdoor operation.
4. Durable, Lightweight Construction
Die-cast aluminum combined with PC (polycarbonate) optics gives a balanced mix of strength, lightness, thermal conduction, and impact resistance. Powder-coated surface finish preserves aesthetics and corrosion resistance in coastal or industrial environments.
5. Professional Photometry & Optics
The SZMTC 2835 LED packages offer uniform color and consistent lumen depreciation behavior. The careful optical design controls glare and distributes light cleanly, reducing dark spots and ensuring safe, visually comfortable environments.
6. High Power Factor & Stable Electrical Performance
With PF = 0.9, the series minimizes reactive power draw — an important metric for large installations to optimize utility billing and ensure compliance with electrical standards.
Typical Applications — Match Wattage to Use Case
- 30W (UT-50-06701): Accent lighting, small garden areas, signage lighting, step/path illumination.
- 50W (UT-50-06702): Residential driveways, small storefronts, canopy accents.
- 100W–150W (UT-50-06703/06704): Medium car parks, loading bays, building facades, small sports courts.
- 200W (UT-50-06705): Large parking areas, warehouses, architectural façade lighting with medium throw.
- 300W–400W (UT-50-06706/06707): Stadium lighting, large yards, highway signage, industrial yards — where long throw and high lumen density are needed.
By selecting the appropriate model, designers can optimize light levels (lux) and uniformity for safety, aesthetics, and regulatory compliance.
Design & Installation Advantages — Less Time, Lower Cost
Compact Profiles & Low Weight
The ETD-50 small sizes (esp. 30W / 50W) mean minimal mounting loads and easier handling during installation. Even the 400W model remains compact compared to old-style metal halide units.
Mounting Flexibility
The fixtures accept various mounting options — yoke brackets, pole mounts, and wall plates — enabling wall-wash, flood, and angled-projection installations. Adjustable brackets allow precise aiming, so installers can dial-in beam spread and minimize light spill.
Low Maintenance Needs
High-quality LEDs and DOB arrangement reduce routine servicing. The PC optics and die-cast body are designed for long life; combined with high CRI stability and minimal lumen depreciation, the total cost of ownership is low.
Performance & Environmental Considerations
Thermal Management
Die-cast aluminum body serves as an efficient heat sink. Proper thermal design keeps junction temperatures low, which slows lumen depreciation and improves lifetime — a critical factor for 24/7 installations like security lighting.
IP / Weather Durability (Recommended)
While specifications you provided focus on material and CCT, in practice these flood lights are typically paired with IP65–IP66-rated sealing to resist dust and heavy water spray. Confirm IP rating at order; IP66 is recommended for exposed outdoor, coastal, and heavy-rain environments.
Color Temperature & Visual Clarity
All models are specified at 8000K (a very cool, bluish-white light). This CCT is excellent for high-visibility and security applications (high contrast, clear identification) but may be perceived as cold for residential or hospitality settings. For façade or architectural work, test samples to ensure the visual effect meets the design brief. (If a warmer option is desired for some projects, discuss custom CCTs with the supplier.)
CRI = 80
A CRI of 80 provides acceptable color rendering for general outdoor and industrial use. For retail façades or locations where color fidelity matters (e.g., art or specific signage), consider higher CRI alternatives.
Energy & Cost Benefits — ROI You Can Count On
Upgrading from legacy HID or HPS flood lights to UT-50 LEDs yields tangible savings:
- Energy Savings: Typical conversions show 50–70% lower energy consumption to achieve equivalent lumens.
- Maintenance Savings: Longer operating life reduces replacement and labor costs.
- Reduced Cooling Loads: Lower heat emission lowers HVAC impact for enclosed spaces.
- Higher Reliability: Less downtime and more predictable service intervals.
For most commercial deployments, payback periods are often realized within 1–3 years depending on operating hours and local electricity rates.
Photometric Planning — Get the Light Right
A successful installation starts with photometric studies (IES files / lighting simulation). UT-50 fixtures produce predictable photometric curves; when used with spacing and aiming best practices, they deliver uniform illumination for roadway, car park, or sports applications.
Key planning tips:
- Use higher wattages for larger mounting heights and wider spacing.
- Aim fixtures to reduce glare toward drivers or pedestrians.
- Combine models: e.g., use 200W for central zones and 100W for perimeter to optimize uniformity and cost.
Safety, Compliance & Warranty
OKELI’s quality processes typically include electrical safety testing, surge protection options, and conformances such as CE / RoHS (confirm per batch). For critical projects, request test reports and warranty details. DOB-based UT-50 units commonly ship with a manufacturer warranty (1–5 years depending on order terms) — valuable for long-term projects.
Real-World Use Cases — Stories from the Field
- Logistics Hub Upgrade: Replacing 250W metal halide units with UT-50 150W/200W LED fixtures produced clearer yard visibility and slashed energy bills by 62% in the first year.
- Storefront & Façade Lighting: Retailer used multiple 50W UT-50 units with precision aiming for crisp storefront illumination that attracted evening foot traffic.
- Sports Court: A community replaced old floodlights with UT-50 300W units to deliver even illumination across courts while cutting maintenance intervals.
These examples show how a single product family can address diverse project needs while simplifying procurement and spares.
Specification Checklist for Buyers
Before ordering, validate these items to ensure the fixture fits your project:
- Confirm exact IP rating (IP65 vs IP66).
- Verify surge protection requirement (e.g., 10kV SPD).
- Request IES photometric files for precise simulation.
- Confirm mounting accessories (yoke, pole adaptor, slip fitter).
- Ask about certificates (CE, RoHS, LM-79 / LM-80 if needed).
- Check warranty period and available spare modules.
How UT-50 Supports Sustainable Projects
By combining high efficacy (100–110 lm/W) with DOB simplicity and durable materials, UT-50 units help organizations meet sustainability targets: less energy, fewer replacements, and lower embodied emissions over the product lifecycle. For municipal and commercial clients, these benefits support ESG reporting and long-term operating budgets.
Ordering & Customization Options
OKELI can support bulk orders with custom labeling, optional photocells, motion sensors, dimming control (where supported), or alternative CCT requests. Discuss project specifications with your account manager to adapt brackets, optics, or finishes for architectural projects.
