I think small CFL replacements for home lighting have been a bad idea from the start, more so when they were made less expensive by cutting corners.
it's a bad idea.
Yet cutting corners is something that's being done with LED as well. What's the best alternative? Incandescent?

However, the last thread I was in, expressing concern about CFL's was a bit nasty. Those who have bought into CFL's, are going to defend their purchase regardless of any fact presented based on my experience in this board.
These days, there's no such thing as "investing" in CFLs. They're 2$-3$ a bulb. What we/they are defending is our choice not to go spend 15$-30$/bulb for LED.
Other studies confirm that yes, UV from fluorescent is bad, but the safe distance is way shorter than real life distances.

The report states that most bare spiral lamps tested gave off more UV than the 60 watt incandescent lamp tested, but that the double-envelope CFLs emitted less UV. At 30 cm distance, the recommended maximum daily exposure was attained between 3 hours and 6 hours, with little difference between the studied 60 Watt incandescent lamp and any bare-spiral CFL. The report states that the Threshold limit values used represent otherwise healthy individuals who are not experiencing any hypersensitivity conditions or exposed to substances that increase UV sensitivity. Outdoor sunlight can supply the maximum recommended daily UV exposure in 20 to 100 minutes.

It's kinda strange that your LED gets hot because i have both Light buld led and GU10 led and the are warm but not hot.
It depends on the heat sink on the bulb. Some are bad, some are good. Either way, LED ballasts head up (hence the need for heat sinks).
