Problem:The overall image appears bluish (cool) or yellowish (warm), failing to meet design requirements. Alternatively, the brightness may be insufficient, making the image hard to see during the day. On the other hand, excessive brightness can cause the image to become “see-through” and glaring. This is often due to purchasing light bars with inaccurate color temperature (e.g., labeled 6500K but actually producing a blue light). There may also be a power mismatch: the total power of the light bars is too low (insufficient brightness) or too high (overexposure).
Solutions:
Color Temperature Correction:
If the light appears too blue (color temperature too high), apply a layer of low-color-temperature diffusion film or warm soft light gel to neutralize it.
If the light appears too yellow (color temperature too low), the light bars must be replaced. Before purchasing, always request the manufacturer to provide real lighting videos or a color temperature report.
Power Adjustment:
Insufficient brightness: Directly replace the light bars with higher power density models.
Overexposed brightness: Use a TRIAC dimmer or a variable transformer to reduce the current. This not only lowers the brightness but also extends the lifespan of the light bars.
