unless necessary.
5. The supply voltage variation should be within ±6% of the rating.
6. Don't look straight at the LED module. Looking straight at it may damage your eyes.
7. The product should be used within an ambient temperature range of -20 to +40°C (temporarily +60°C). Otherwise the service life may be
shortened.
8. Confirm that the fitting is adequately grounded.
9. Prior to maintenance or inspection, be sure to turn off the power.
10. To prevent shortening of the service life, avoid turning on the fitting in direct sunlight.
11. To avoid noise or malfunctioning, don't use a radio, television or wireless infrared remote control near the fitting.
12. In the case of white LEDs, luminescent color and brightness may vary with individual LEDs. Also note that they differ in terms ofattenuation over time.
13. The product must be mounted on a sturdy wall surface or structure which is vibration-free and less susceptible to damage. Otherwise, it
might fall or be damaged.
14. Mount the product on a flat smooth surface. Don't use the product with stress on it.
15. The product must be oriented in a specified manner.

A lighting fitting has a service life. A product which has been used for eight to ten years may have degraded internal partseven if it looks normal. For safety and energy saving, we recommend you check and replace it. The LED module design life is60,000 hours (different from the lighting fitting life) when used at an ambient temperature of 30°C, 10 hours per day, 3,000
hours per year. If used at a higher temperature or more hours per year, the life would be shortened. Have a specialist
inspect the product every three years. If used for an extended period without inspection, a smoke, fire, or electric shockmight result.
