In practice: LEDs can be run just as inefficiency (or worse) than CCFLs. It depends on:
- Quality of the leds
- How hard they are being pushed (efficiency drops as you increase power)
- How well they are cooled (efficiency drops as temp rises)
Why is the bulb so different and why is it not designed to be cool?
Can you provide a photo of the bulb + what wattage it claims to consume? Some quick estimations on the explanation can be made from there.
In this case it was bulb up, socket down, so heat should have radiated up and away from the socket and electrical components.
I'll be a little anal here: convected, not radiated. Radiation is not effected by gravity (at this scale). If the bulbs were in enclosures (glass covers, etc) then the convection would be contained and cooling hampered considerably.
Yes, correction noted... It is CONVECTION. As such, I have included some photos of the hardware in question below and will explain the poor design which is why I think it is leading to overheating. I will also show you what I did to hopefully improve the situation, but I am not sure if it is necessarily going to make a huge difference or not.
Here is the lamp, it is composed of a base and another long rotating tube that slides inside of it. The idea is, when it is rotated so that the opening in the rotating tube lines up with the white plastic at the front, it lets all the light out. You can rotate the "hexagon" on top which rotates the cylinder inside and provides various decrease of "shuttering" of the opening, with the result that if you turn it 180-degrees you stop all light from exiting the lamp. This way you can adjust the amount of light, but also accidentally leave it on without realising it as it would appear dark with a bulb burning inside of it 24/7:
You can see the lamp here with the bulb, and then removed, some plastic pieces still stuck at the bottom that flaked off the bulb:
Here is the information on the base of the lamp. I *DID* follow the specified ratings, I made sure of it, knowing that it was an enclosed area I specifically went for an LED when the CFL (that came with it) burned out also after a relatively short period of time, and the reason I got the LED was exactly because I thought it was going to last longer and not get as hot!!!!!! It would have been 9W max. Here is the info:
