Using these Philips halogen globes is easy. Just make sure your downlight or rangehood is turned off before installation. Gently insert the bulbs into the socket, aligning the pins properly. When using, avoid touching the glass part of the bulb with bare hands as the oils from your skin can cause the bulb to overheat and reduce its lifespan. If you do touch the bulb, clean it with a soft, dry cloth. For maintenance, check the bulbs regularly for any signs of damage or dimming. Replace any faulty bulbs promptly to ensure consistent lighting. Keep the bulbs in a cool, dry place when not in use.
