I have a covered porch in front of my living room. Two ceiling lamps with E27 bulbs have been installed there for 15 years. Now I want to replace them with Philips. E27 Philips don't fit because of the diameter. I would like the Philips panels best. However, according to Philips, these and all other ceiling lights are not suitable for outdoor use. Can I still mount them outside? They would be mounted underneath a terrace and thus protected from rain and weather.
