1. How long does EL cold light last?
Answer: The lifespan of a conventional EL cold light sheet is about 3,000~8,000 hours (affected by the driving voltage, frequency, ambient temperature and humidity).
Extension recommendations: Reduce the driving voltage (such as from 110V to 60V) to avoid long-term high-frequency operation.
2. Why is the EL cold light brightness lower than that of LED?
Answer: EL is a surface light source, with soft and uniform light, but the single-point brightness is weaker than that of LED point light sources. Suitable for scenes that require no glare and large-area luminescence (such as backlighting, decoration).
3. What driving conditions are required for EL cold light?
Answer: AC electric drive is required (usually 400~1000Hz, voltage is 60~150V), and it needs to be equipped with an inverter (DC 3V/12V to AC high voltage).

1. Can EL cold light sheets be cut or punched?
Answer: You can cut along the edge, but you need to avoid damaging the electrode layer; punching may cause local short circuits, so it is recommended to customize the special-shaped size.
2. How to improve the waterproof performance of EL cold light?
Answer: Through surface coating (such as PET waterproof coating) or glue-filled packaging, the IP level can reach IP65 (the requirements need to be explained in advance).
3. Is EL cold light available at low temperatures?
Answer: The working temperature range is usually -20℃~60℃, and the brightness may drop at low temperatures. It is recommended to choose a wide temperature model (such as for car dashboards).

troubleshooting
1. What should I do if some areas of the EL cold light sheet are not lit?
Cause: Poor electrode contact, line break, insufficient driving voltage.
Solution: Check the electrode connection point, replace the inverter to test, and avoid excessive bending.
2. Flashing problems occur during use of EL cold light
Cause: Unstable driving voltage, mismatched frequency or poor line contact.
Solution: Replace the stable power supply to ensure that the inverter frequency matches the product (such as 500-600Hz).

1. Why is the cost of EL cold light higher than that of LEDs?
Answer: Material costs (phosphorescence layer, multi-layer film structure) and driving circuit complexity lead to high initial costs, but low long-term maintenance costs (no heat dissipation and low power consumption).
2. Does it support custom shapes, colors and sizes?
Answer: Supports full customization (mold opening fee required), colors can be selected from blue, green, white, orange, etc., and the maximum size can reach 100CMX200CM (due to process limitations).

1. Does EL cold light meet environmental protection standards?
Answer: Mainstream products have passed RoHS and REACH certification and are free of harmful substances such as mercury. Some materials are recyclable.
2. Is there any fire-proof and flame retardant certification?
Answer: UL94 V-0 flame retardant grade can be provided (instructions are required in advance, and the materials require special treatment).

1. Can EL cold light sheets be machine washed with clothing?
Answer: You need to choose a flexible packaging model. Machine washing may shorten the lifespan. It is recommended to wash by hand (disconnect the power supply and avoid soaking).
2. Will EL cold light interfere with the circuit when used in automotive instrument panels?
Answer: EL has no electromagnetic radiation and is highly anti-interference, and complies with the ISO 7637 standard of automotive electronics.

1. What is the minimum order quantity (MOQ)?
Answer: Standard MOQ is usually 100~500 pieces, and customized orders are adjusted according to complexity.
2. How long is the after-sales warranty period?
Answer: Regular warranty of 3 months (non-human damage), technical support and replacement parts service
