The XD5 150W UFO high bay is the most versatile wattage in Probapro’s XD5 series. It delivers enough output for 20- to 30-foot ceilings without the upfront cost or intensity of the 200W and 240W models, making it the default choice for warehouses, workshops, gyms, and light assembly facilities.
Most buyers still shop by wattage. That is a mistake. A 150W fixture from one manufacturer can deliver 19,000 lumens; another can deliver 24,000. The XD5 150W sits at the higher end of that range, but the real question is whether it fits your ceiling height, task requirements, and spacing plan.
In this guide, you’ll get the full XD5 150W specifications, real coverage estimates, application guidance, and a direct comparison with the 100W, 200W, and 240W models. By the end, you’ll know whether the 150W is the right fixture for your facility or if you should step up or down in the XD5 series.
Key Takeaways
- The XD5 150W produces 22,500–24,000 lumens at 160 lm/W, ideal for 20–30 ft ceilings.
- It replaces 250W–400W metal halide fixtures while drawing roughly one-third of the power.
- Pair it with a 90° beam angle for most warehouse and workshop applications.
- Energy savings typically recover the fixture cost in 1.5–2.5 years for facilities running 12+ hours daily.
- The XD5 series shares the same mounting interface, so you can swap wattages later without changing hardware.
What the XD5 150W UFO High Bay Light Is
The XD5 150W is part of Probapro’s industrial-grade UFO high bay series. It is a round, compact LED fixture designed for ceilings between 20 and 30 feet, though it can work well in taller spaces when paired with a narrower beam angle.
For a broader introduction to UFO high bay technology, see our complete UFO high bay light guide.
Inside the die-cast aluminum housing, the LED board, driver, and heat-dissipation fins are integrated into a single sealed unit. That matters in industrial environments. Fewer connection points mean fewer failure points. Heat flows directly from the LED chips into the finned housing, which keeps junction temperatures lower and extends the fixture’s useful life.
The 150W model sits in the middle of the XD5 lineup. It is not the entry-level option, and it is not the maximum-output option. It is the workhorse. For facility managers who need reliable light levels across a wide range of tasks without over-lighting their space, it is often the best starting point.

The 160 lm/W efficacy is the headline number. At 150 watts, that translates to 24,000 lumens in the high-output configuration. Many competing 150W fixtures advertise 130–150 lm/W, which means you need more fixtures to hit the same light level on the floor.
For context on how lumens translate to usable floor light, see our guide on how many lumens you need for high bay lighting.
What the XD5 150W Replaces
Direct Fixture Replacements
| Existing Fixture | XD5 150W Replacement |
|---|---|
| 250W metal halide | Direct 1:1 replacement in most 20–25 ft spaces |
| 400W metal halide | Direct 1:1 replacement with improved light levels |
| 200W–250W high-pressure sodium | Equivalent or better floor illumination |
| 4-lamp T5HO high bay | Comparable output with lower energy draw |
Wattage ratings on legacy fixtures are misleading. A 400W metal halide fixture actually draws about 458 watts when you include ballast losses. It also loses 20% of its output in the first six months and up to 50% by mid-life. The XD5 150W draws 150 watts actual and maintains its output across the rated lifespan.
For a complete comparison of LED and metal halide performance, read our guide to LED vs metal halide savings.
That difference shows up in your electrical panel and your maintenance budget. You are not just buying a replacement light. You are buying a fixture that stops the cycle of lamp replacements, color shift, and lumen depreciation.
Best Applications for the XD5 150W
Warehouses & Distribution Centers
Open floor plans with 20–25 foot ceilings are where the XD5 150W performs best. The 90° beam angle provides balanced coverage across aisles and picking zones without wasting lumens on the walls. In low-traffic aisles, add an external microwave motion sensor to dim the fixture when no one is present. That can cut energy use by another 20–40%.
Manufacturing & Assembly
Light to medium assembly tasks typically need 30–50 foot-candles. The XD5 150W can deliver that at normal mounting heights, and the CRI above 80 supports color-critical work like quality control and electronics inspection. Flicker-free output also reduces eye strain during long shifts.
Workshops & Garages
Smaller industrial spaces often over-light when facility managers spec 200W or 240W fixtures. The 150W provides strong illumination without glare or wasted energy. For ceilings under 20 feet, pair it with a 120° beam angle for wider, softer coverage.
Gymnasiums & Sports Facilities
Community gyms and training facilities with 20–25 foot ceilings can use the XD5 150W with 90° or 120° beams. The IK08 impact rating handles routine ball contact, and instant-on performance means no warm-up time between events.
Retail & Showrooms
High-ceiling retail spaces benefit from the clean, circular form factor. The 4000K option renders merchandise naturally, while the 5000K option provides a cooler, daylight-like appearance for showrooms and exhibition halls.
XD5 150W vs Other XD5 Wattages
XD5 100W vs 150W
| Factor | 100W | 150W |
|---|---|---|
| Lumens | 15,000–16,000 | 22,500–24,000 |
| Best Ceiling Height | 15–20 ft | 20–30 ft |
| Typical Spacing | 12–16 ft | 15–20 ft |
| Annual kWh (12 hrs/day) | 438 | 657 |
| Best For | Workshops, small retail | Warehouses, gyms, assembly |
The 100W is the right choice for lower ceilings and smaller spaces. Step up to the 150W when you need more throw, wider spacing, or higher foot-candles.
XD5 150W vs 200W
| Factor | 150W | 200W |
|---|---|---|
| Lumens | 22,500–24,000 | 30,000–32,000 |
| Best Ceiling Height | 20–30 ft | 25–35 ft |
| Typical Spacing | 15–20 ft | 18–24 ft |
| Annual kWh (12 hrs/day) | 657 | 876 |
| Best For | Standard warehouse | Deep-ceiling distribution centers |
The 200W is worth the extra cost when you have 25-foot-plus ceilings or need higher light levels for detailed tasks. For most 20–25 foot warehouse and factory applications, the 150W is enough.
XD5 150W vs 240W
| Factor | 150W | 240W |
|---|---|---|
| Lumens | 22,500–24,000 | 36,000–38,400 |
| Best Ceiling Height | 20–30 ft | 35+ ft |
| Typical Spacing | 15–20 ft | 22–28 ft |
| Annual kWh (12 hrs/day) | 657 | 1,051 |
| Best For | General industrial | Airport hangars, bulk storage, high-bay racks |
The 240W is a specialized tool for very high ceilings. Using it in a 20-foot workshop is overkill and will create glare complaints.
Quick Decision Framework
- Under 20 ft ceilings: Start with the 100W.
- 20–30 ft ceilings: The 150W is usually the right choice.
- 25–35 ft ceilings: Consider the 200W.
- 35+ ft ceilings: Go with the 240W.
For more on general wattage selection principles, see our high bay light wattage guide.
Beam Angle Selection for the XD5 150W
Beam angle is as important as wattage. The wrong angle will leave you with bright spots under each fixture and dim aisles in between.
Ceiling Height Guide
| Ceiling Height | Recommended Beam Angle | Why |
|---|---|---|
| 15–20 ft | 90°–120° | Wider spread at short throw |
| 20–30 ft | 90° | Balanced coverage and intensity |
| 30–40 ft | 60°–90° | Tighter throw for deeper ceilings |
| 40+ ft | 60° | Maximum intensity at distance |
For most warehouses and workshops, the 90° beam is the safe default. Use 120° only when you need wide, uniform coverage at lower mounting heights. Use 60° when you need to push light down from 30 feet or more.
XD5 150W Coverage & Foot-Candle Estimates
These estimates assume clean optics, typical warehouse reflectance, and a 90° beam angle. Your actual results will depend on ceiling color, floor reflectance, and obstructions like racking or equipment.
Performance by Mounting Height
| Mounting Height | Spacing | Coverage per Fixture | Estimated Foot-Candles |
|---|---|---|---|
| 20 ft | 15–18 ft | ~225–325 ft² | 35–50 fc |
| 25 ft | 18–20 ft | ~325–400 ft² | 25–40 fc |
| 30 ft | 20–22 ft | ~400–484 ft² | 20–30 fc |
Quick Fixture Count Formula
To estimate how many XD5 150W fixtures you need:
Fixture count ≈ (Target foot-candles × Area in ft²) ÷ (Fixture lumens × 0.75)The 0.75 factor accounts for light loss from dust, reflectance, and optical inefficiency. Always confirm the final layout with the manufacturer’s IES file in a lighting design tool like DIALux or AGi32.
Energy Savings & ROI with the XD5 150W
Per-Fixture Savings vs Metal Halide
| Metric | 250W Metal Halide | 400W Metal Halide | XD5 150W |
|---|---|---|---|
| Actual Power Draw | 290W | 458W | 150W |
| Annual kWh (12 hrs/day) | 1,271 | 2,007 | 657 |
| Annual Cost (@ $0.13/kWh) | $165 | $261 | $85 |
| Annual Savings vs MH | — | — | 80–80–176 |
The average US commercial electricity rate is around 0.13perkWh, according to [EIAdata]. At that rate, a single XD5150W saves 0.13 per kWh, according to [EIAdata]. At that rate, a single XD5150W saves 80 to 176 per year compared to legacy HID fixtures. A 100-fixture facility saves 176 per year compared to legacy HID fixtures. A 100-fixture facility saves $8,000 to $17,600 annually on energy alone.
Maintenance Savings
Metal halide lamps last 15,000 to 20,000 hours. In a 24/7 operation, that means replacements every two years. Add lift rental, labor, and disposal, and the cost runs 50to50to100 per fixture per year.
The XD5 150W is rated for 50,000 hours L70. At 12 hours daily, that is 11 years of maintenance-free operation. At 24/7, it is still 5.7 years.
Payback Example
Jennifer manages a 150-fixture factory in San Diego running two shifts, 16 hours daily. She replaced 400W metal halides with XD5 150W units.
- Annual energy reduction: 200,400 kWh
- Energy cost savings: $26,052 per year
- Maintenance savings: $8,500 per year
- Total first-year savings: $34,552
- Project cost after DLC rebate: $42,000
- Payback period: 1.5 years
DLC Premium certification unlocks utility rebates that can cover 10–50% of fixture cost depending on the utility. You can verify DLC qualification on the Design Lights Consortium website.
Installation Notes for the XD5 150W
The XD5 150W shares the same mounting interface as the rest of the XD5 series. That means you can change wattages later without replacing chains, rods, or brackets.
Mounting Options
- Hook mount: Hang from a ceiling hook or eye bolt. Most warehouses use this.
- Pendant rod: A rigid rod for fixed drop length, ideal where airflow or vibration would sway a chain.
- U-bracket: Surface or wall mounting when ceiling suspension is not practical.
- Conduit: Threaded conduit entry for clean, code-compliant electrical connections.
Electrical Requirements
The XD5 150W accepts AC 100-277V input directly. No ballast. No capacitor. If you are replacing metal halide or fluorescent fixtures, you must bypass or remove the existing ballast. Connecting line voltage through a ballast will damage the driver and void the warranty.
Common Installation Mistakes
- Wrong beam angle: A 120° fixture at 35 feet wastes lumens on the walls.
- Poor spacing: Spacing fixtures at 45 feet on 25-foot ceilings creates dark corridors.
- Ignoring the environment: Using IP65 fixtures in daily wash-down areas without the IP66 option.
- Skipping the layout plan: Installing before calculating fixture count and placement.
