Using these Philips halogen globes is easy. First, make sure your light fixture is turned off and has cooled down. Then, gently insert the GU10 base of the globe into the socket until it fits snugly. When it comes to maintenance, keep the globes clean by using a soft, dry cloth to wipe off any dust or dirt. Avoid using harsh chemicals or abrasive materials as they can damage the globe. Also, always follow the manufacturer's wattage recommendations for your light fixture. If you notice any flickering or the globe stops working, replace it promptly to avoid any electrical issues. These globes are suitable for many downlight applications, so you can use them to brighten up different areas of your home or office.
