Ra can be lower than IP65 waterproof led floodlight, but safety colors must be distinguishable. When purchasing LED spotlights, you need to read the instructions or packaging instructions provided by the manufacturer in detail to determine the product's power supply voltage and product related parameters, including luminous flux, color temperature, power, color rendering index, angle, etc. In indoor lighting, when purchasing LED spotlights, you must first determine whether to use direct power supply from the city or use a transformer to supply power, so as to choose whether to buy MR16 or other spotlights; secondly, determine the lamp holder and Light size; again need to confirm the angle range of the required spotlight; finally, according to the requirements of the above-mentioned "GB 50034-2004 Architectural Lighting Design Standard", the color temperature and color rendering index can be confirmed according to the use occasion to achieve the desired lighting effect. If you don’t know the parameters of the lamp very well, you can check the equivalent mark on the package to see how much power is equivalent to a traditional lamp to make a selection. As the existing LED spotlight technologies of various manufacturers are uneven, in order to solve the problem of heat dissipation and power supply space, many manufacturers do not completely refer to IEC 60630 to design the spotlight shape. The spotlight is sometimes used as the light source of some lamps, so it is necessary to clarify whether the LED spotlight can be installed in the lamp. If it cannot be installed, it is necessary to purchase a matching lamp housing for integral replacement. For MR16 spotlights, because there is an electronic transformer or a power frequency transformer at the front end, you need to confirm whether it is compatible with the transformer when purchasing MR16. If it is not compatible, the light will flash or not light up. For thyristor dimming spotlights, it is also necessary to consider the compatibility of the lamp and the dimmer, otherwise the lamp flickers or cannot be dimmed during dimming. The structure of the lamps and lanterns contends
