1. Please confirm the voltage first. If the voltage of a product is 12V-24V, then you must use a professional LED voltage converter. 2. Please check the specifications of the product carefully before ordering to insure a proper fit. 3. Do not disassemble any bulbs by yourself. 4. Be sure to cut the power off before beginning installation to avoid personal injury.
The strength of the light is excellent, and the spreading is OK.
