I got a lamp that listed out the limitation of the watt as Max 60W E27 (Max 60W Incan ~ Max 42W Halo ~ MAX 10W LED). At the beginning I only think that max watts of the lamp is 60W then I purchased and used a fluorescent Philips bulb at 32W for more than 6 months. Now I want to change to the higher lumen bulb and notice about the warning “Max 60W Incan ~ Max 42W Halo ~ MAX 10W LED”. I am not quite sure is that possible for me to use a LED bulb at 18W or as long as I am not exceed the 60W limitation OR I have to follow their warning like LED bulb has to be 10W? Thanks

Incandescent bulbs are made of glass and steel and happily run at very high temperatures. For them, the 60 W limit is there mostly to avoid setting fire to the light fitting.
LED bulbs work using a bunch of semiconductors which are much more heat sensitive. For them, the 10 W limit is to allow them to stay cool enough. If you use a higher wattage LED, expect a short life span and, if you go too high, the bulb itself could catch fire.
