How to select WEHO HLG, XLG, LPV and WL products for outdoor, architectural, industrial and space-constrained LED lighting.
DIRECT ANSWER: An LED lighting power solution starts by matching the luminaire’s required output mode, voltage, current and wattage, then checking input range, dimming, environmental protection, cable loss and thermal derating. WEHO HLG and XLG families address compatible sealed outdoor and industrial lighting, LPV supports constant-voltage LED branches and WL provides an ultra-thin option for indoor commercial or light-box installations.
1. What Is a LED Lighting Power Solution?
An LED lighting driver and power supply solution converts the AC input into the electrical output required by a luminaire or LED load. Depending on the product, the output can be constant voltage, constant current or constant power. The complete system also includes branch protection, surge strategy, grounding, dimming interface, cable sizing, enclosure and thermal design.
Zhejiang Weihao Electronic Co., Ltd. (WEHO) supplies HLG and XLG sealed LED power families, LPV waterproof constant-voltage products and WL ultra-thin LED supplies. These families serve different power levels, output modes, form factors and environments. The exact driver must be matched to the luminaire; voltage alone is not enough to confirm compatibility.
Solution at a Glance
| SYSTEM REQUIREMENT | RELEVANT WEHO PRODUCT | PRIMARY ROLE |
| Outdoor or industrial constant-voltage load | HLG-250 | Sealed fanless LED power |
| Protected outdoor lighting | XLG-150 | Waterproof LED driver family |
| Architectural strips or signs | LPV-100 | Encapsulated constant-voltage power |
| Shallow indoor installation | WL-300 | Ultra-thin 12 V or 24 V LED power |
2. How Should the LED Lighting Power System Be Structured?
Start with the LED load data: output mode, operating voltage, current, wattage and dimming method. Then select the driver input and environmental class. A constant-voltage supply is not interchangeable with a constant-current driver unless the luminaire is designed for that source.
Electrical match: Confirm constant-voltage, constant-current or constant-power behavior and the complete operating range of the LED load.
Environment: Match the driver and junction system to indoor, outdoor, wet, dusty, corrosive or high-temperature conditions.
Control: Verify whether the exact model supports the required dimming or control interface; do not infer dimming from the series name.
3. What Problems Does the WEHO Solution Address?
| THE DESIGN CHALLENGE | THE WEHO RESPONSE |
| Wrong output mode A voltage match alone does not prove compatibility with an LED luminaire. | Match output mode, operating range, current, wattage and control method to the luminaire specification. |
| Outdoor exposure Water, dust, condensation and surge conditions affect the entire installation. | Use a suitable sealed driver and design junctions, cable glands, grounding and surge protection for the site. |
| Cable voltage drop Long low-voltage runs can reduce brightness or create uneven zones. | Calculate conductor drop at full load, shorten branches or locate drivers closer to the LED load. |
| Thermal derating Driver life and available power depend on case and ambient temperature. | Provide heat dissipation, installation clearance and exact-model derating based on the real mounting location. |
4. Which WEHO Products Fit the LED Lighting Applications?
A complete system may combine more than one product family. Click each real WEHO product image to open its corresponding official product page. Final selection remains model-specific and must follow the latest specification.
 HLG-250 waterproof LED power HLG series Fanless, sealed constant-voltage LED power for compatible outdoor or industrial lighting loads. Confirm required voltage, wattage and installation environment. |  XLG-150 waterproof LED driver XLG series Protected outdoor LED driver for compatible constant-voltage or constant-power lighting systems. Verify output mode against the luminaires. |
 LPV-100 waterproof LED power LPV series Encapsulated constant-voltage power for compatible indoor or outdoor LED strips, signs and architectural lighting branches. |  WL-300 ultra-thin LED power WL series Ultra-thin 12 V or 24 V enclosed supply for space-constrained LED display, light-box or commercial lighting installations. |
5. Where Is This LED Lighting Power Solution Used?
Street and area lighting: Use compatible sealed drivers with site-level surge, grounding and environmental protection.
Architectural façade lighting: Power constant-voltage strips or fixtures by zone while controlling cable drop and junction access.
Industrial high-bay lighting: Select for the luminaire, high ambient temperature, duty cycle and maintenance access.
Commercial and retail lighting: Use compact or ultra-thin supplies where ceiling, cabinet or light-box depth is limited.
Signage and landscape lighting: Coordinate sealed drivers, cable routes, voltage drop and branch protection for outdoor installations.

6. How Do You Select a LED Driver or Power Supply?
Identify the output mode: Confirm whether the LED load requires constant voltage, constant current or constant power.
Map the operating range: Record voltage, current, wattage, startup, dimming and number of luminaires or LED branches.
Define input and environment: Confirm AC range, outdoor or indoor location, moisture, dust, temperature, surge and installation enclosure.
Calculate cable loss: Use conductor length, size and full-load current to verify voltage at the luminaire or farthest LED segment.
Check thermal integration: Review case temperature, mounting surface, ventilation, spacing and exact-model derating.
Validate the lighting system: Test full load, low line, high ambient, dimming range, switching, surge strategy and visual uniformity.
ENGINEERING NOTE: Constant-voltage, constant-current and constant-power outputs are different electrical behaviors. Always use the luminaire or LED module specification to select the driver; never select by wattage alone.
7. Why Use a Coordinated WEHO LED Lighting Power Architecture?
Multiple environmental formats: HLG, XLG and LPV provide sealed options for compatible outdoor or protected lighting roles.
Space-constrained installation: WL provides an ultra-thin alternative for compatible indoor lighting and light-box loads.
Application-specific matching: The portfolio spans different output ranges, form factors and protection concepts.
Clear engineering workflow: The architecture prioritizes output mode, cable drop, thermal design and environmental protection.
8. Frequently Asked Questions
What is the difference between an LED driver and a power supply?
The terms overlap, but the key engineering distinction is the output behavior. Confirm whether the LED load needs constant voltage, constant current or constant power.
Can I replace a constant-current driver with a 24 V power supply?
Only if the luminaire is specifically designed for a 24 V constant-voltage input. Otherwise the electrical behavior is incompatible.
Which WEHO series is best for outdoor lighting?
HLG, XLG and LPV include sealed products, but the correct choice depends on output mode, voltage, current, wattage, input, temperature, dimming and environmental requirements.
How do I size a driver for LED strips?
Use the strip voltage, watts per meter, installed length, branch layout, cable loss and any manufacturer limits. Add margin using the exact driver derating and real temperature.
Does an IP-rated driver make the whole system waterproof?
No. Junctions, connectors, cable glands, splices, grounding and the luminaire must also meet the environmental requirement.
Can every HLG or XLG model be dimmed?
Do not assume so. Verify the exact model’s control wires and dimming interface on the current specification.
What should I send WEHO for selection?
Provide output mode, LED voltage/current/wattage, input range, dimming method, indoor/outdoor conditions, cable length, ambient temperature and quantity.
