Using these Philips LED bulbs is easy. Just screw them into a compatible SES socket. They're great for lighting up your refrigerator or other home areas. Remember, don't use them in ovens or microwaves as they're not designed for such high - heat environments. To keep them in good condition, handle them gently. Avoid touching the bulb surface with bare hands as the oils from your skin can cause uneven heating and potentially reduce the bulb's lifespan. If you need to clean them, wait until they're completely cool and use a soft, dry cloth. With our 25 - year experience in supplying appliance parts, you can trust these bulbs to serve you well.
