What is the HL200?
A headlight tester built for real comparison data.
Letrava HL200 is an automotive headlight tester designed to measure illuminance in lux and correlated color temperature (CCT). It allows high beams and low beams to be measured separately and can monitor headlight output continuously to reveal changes after warm-up.
In practical terms: HL200 helps you compare a stock bulb with an upgrade, compare two lighting options, check left/right consistency, or determine whether light output fades as an LED headlight heats up.
Core Functions
More than a single brightness reading.
HL200 is designed for repeatable automotive headlight testing where brightness, color temperature and output stability all matter.
CCT Measurement
Compare correlated color temperature to see the measured color difference between headlight setups.
Separate Beam Testing
Evaluate high-beam and low-beam performance independently instead of combining both into one result.
Output Drop
Quantify how much measured illuminance changes from the beginning of a continuous test to the current reading.
Trend Curve
Follow output over time instead of judging a headlight from a single reading immediately after switch-on.
MAX / MIN / AVG / CURRENT
Continuous Test summarizes the measurement history so output stability is easier to understand.
Separate Measurement
Test high and low beams independently.
High beam and low beam serve different driving functions. HL200 keeps the two measurements separate, helping you evaluate each beam mode on its own rather than relying on one combined number.
01
High Beam
Measure long-range headlight output at your controlled test position.
02
Low Beam
Measure low-beam illuminance independently under the same test setup.
03
Lux + CCT
Review measured brightness and color-temperature data together.
Continuous Test
Bright at start. But what happens after warm-up?
LED headlight output can change as the system warms up. A single reading at switch-on can miss that behavior. HL200 Continuous Test tracks measured output over time and shows how performance changes.
↑
MAX
Highest recorded illuminance during the test.
↓
MIN
Lowest recorded illuminance during the test.
Ø
AVG
Average measured illuminance across the test period.
●
CURRENT
Latest reading compared with the beginning of the test.
Warm-Up Fade
See output loss instead of guessing it.
Use the trend curve and output-drop percentage to compare a headlight at the beginning of a test with its later performance. This is useful when evaluating thermal fade, driver behavior and real operating stability.
Applications
Built for headlight upgrades, comparisons and shop work.
Keep the measurement conditions consistent and use HL200 to turn headlight changes into data that can be compared and documented.
Recommended Test Method
How to get meaningful comparison data.
Lux depends on geometry. For useful comparisons, repeat the same setup instead of changing the distance or aiming between measurements.
Fix the vehicle position
Park on the same level surface and keep the vehicle location unchanged between comparison tests.
Fix the tester position
Place the HL200 at the same distance, height and orientation for every test.
Select the beam mode
Measure high beam and low beam separately so results are not mixed.
Compare under the same conditions
Use the same setup for stock vs. upgrade, A/B bulbs or warm-up testing.
Before / After
Turn a headlight upgrade into numbers you can show.
Visual brightness can be misleading. A controlled before/after test helps document the measured change in illuminance and color temperature.
✓
Compare upgrades
Measure the same headlight position before and after installation.
✓
Compare options
Use the same geometry to compare two bulbs or two lighting setups.
✓
Document results
Keep measurement data for your own records or customer communication.
Lux vs. Lumens
Why HL200 measures lux.
Lumens describe total light emitted by a source. Lux describes illuminance reaching a surface or sensor. The HL200 measures lux at the tester position.
That means a lux comparison is most useful when the distance, height, aiming, vehicle position and tester position stay the same. Use controlled conditions to compare one setup with another.

FAQ
HL200 questions, answered.
Short answers to the questions most relevant to automotive headlight testing.
What does the HL200 headlight tester measure?
HL200 measures automotive headlight illuminance in lux and correlated color temperature (CCT). It also supports continuous testing so you can see output changes over time.
Can HL200 test high beams and low beams separately?
Yes. High-beam and low-beam measurements are kept separate, which makes it easier to evaluate each beam mode independently.
Can it check LED headlight warm-up fade?
Yes. Continuous Test displays a trend over time together with MAX, MIN, AVG, CURRENT and the output-drop percentage from the start of the test to the current reading.
Can I compare a stock bulb with an LED upgrade?
Yes. Keep the vehicle position, tester distance, tester height and aiming conditions consistent, then compare the measured lux and CCT before and after the change.
Is lux the same as lumens?
No. Lumens describe total emitted light, while lux describes illuminance reaching a surface or sensor. HL200 measures lux at the tester position.
Who is HL200 useful for?
It is useful for automotive lighting shops, technicians, LED headlight installers and vehicle owners who want repeatable data for upgrades, A/B comparisons and output-stability tests.
