I want to replace a CFL bulb. It's failed after a few years and I'm not sure to replace it with the same. Perhaps xwitch out other CFLs in the house too. Is an LED bulb better for a room pendant fitting? The old bulb is bright at 35W (175W tungsten):

You don't really want to put LED bulbs in a globe. The bulb should have some airflow. Bulbs come in different color temperatures. Your CFL might be 6500K, which is blue-white. There is 4500K (my kitchen LED, not as irritating as 6500K or unnatural 9000K would be). You want the kitchen light to be "a bit edge-ish", a "keep me awake" light. There is 3500K (my computer room, sorta reddish like an incandescent). For your relaxing room, your sleeping on the couch room, you want something that isn't as much of a poke-in-the-eye. On a bicycle, where the power is generated locally, you might want a 9000K bulb, because they're the most efficient, and people will see you. But for a reading lamp, you want to tone it down. You can have any power you want on LEDs. There are some modules that run a couple hundred watts -- the gotcha, is making a cooler to remove the heat. It would take a fair amount of forced air for something like that. Whereas in most situations, the cooling is via convection...

TIme to switch over from CFL bulbs?

Do you mean whites change to a shade of yellow/orange as the traditional filament bulb gets turned on?

I do. Smiths, Made in England, bought 1985 and still going strong with the original 60 watt bulb. However it is an ancient design that sits there 24 hours a day using 20 watts of power, so it is plugged into a mechanical timer that only activates it from about 8PM to 1AM
