Why Real Data Matters
Many suppliers exaggerate specifications. At LEZEN, we provide actual power meter and lux meter readings to ensure our wholesale partners can confidently guarantee performance to their retail networks.
Tested Output, Cooling & Beam Performance
Verified factory testing data proving the reliability and superior illumination of the M38 series.
Power Stability Test
- Initial Startup: 150W (0 mins)
- 5 Min Mark: 100W
- 30 Min Mark: 95-100W (Stable)
- Test Env: 25°C Ambient, 13.5V
Maintains over 85% of startup power continuously, outperforming standard single-pipe designs.
Thermal Management
- Structure: 3x Liquid Copper Pipes
- Fan Speed: 12,000 RPM Turbo
- Body Temp (30m): < 95°C
- Driver Temp (30m): < 85°C
The triple-pipe system rapidly transfers heat away from the 5080 CSP chips, preventing premature burnout.
H4 Beam Pattern Test
- Low Beam: Sharp cut-off line, no glare
- High Beam: Focused center hotspot
- Comparison: 600% brighter than Halogen
- Dark Spots: Zero dark spots
1:1 halogen filament position ensures perfect compatibility with standard reflector housings.

Check Fitment Before Bulk Ordering
M38 bulb compatibility depends on the original bulb base, headlamp housing space, dust-cover clearance, and vehicle electrical system. Minimizing aftermarket returns starts with correct fitment.
-
Housing Space (External Driver) The M38 features a larger heatsink and an external driver to handle 300W. Ensure the target vehicle housing has sufficient depth. Extended dust covers may be required for compact housings.
-
CANBUS Systems While highly compatible, certain sensitive European or late-model American vehicles may still require external CANBUS decoders to prevent dashboard errors or flickering.
-
Adjustable Beam (360°) The mounting collar is 360-degree rotatable (on most bases) allowing installers to perfectly align the LED chips horizontally (3 o'clock and 9 o'clock) for optimal beam patterns.

M38 FAQs
How is the 300W calculated?
The 300W rating refers to the combined nominal peak power of a pair of bulbs (150W per bulb). As shown in our test data, the actual stable operating power after 30 minutes is approximately 95W-100W per bulb to ensure thermal safety and longevity.
Can I mix different bulb bases in one trial order?
Yes, you can mix different bases (e.g., H4, H7, 9005) within a single standard MOQ order (50 sets total). This allows you to test multiple models in your market simultaneously.
Do these bulbs require external CANBUS decoders?
The M38 has a built-in intelligent driver that handles 90% of vehicle systems without error. However, for certain sensitive vehicles (like newer Dodge, Jeep, or German models), an external CANBUS decoder may still be required. We supply these decoders separately.
How does the warranty replacement work?
We offer a straightforward warranty. If a bulb fails within the warranty period, simply cut the wire, take a photo/video showing the serial number, and we will include the replacement free of charge in your next bulk shipment. No need to ship defective units back to China.
