Hi guys...bought so E14 5w 470lm candle type bulbs today to replace some that were loosing the brightness.
I was quite surprised to find the plastic base gets quite hot cant keep your fingers on them...the glass part is not overlay hot.

And for some reason after fitting they need a further 1/2 a turn to tighten into the holders after being switch on for a while...

They are e-luminate brand at £1.30 each made in China.

Should I be concerned.

Nick.

Both your issues point to poor contact between lamp and socket.

And be wary of using the word 'bulb' on here as it can trigger certain people who don't get out much.

So I take it they should not get hot.....or work loose?
No Nick, they shouldn't. They do not sound safe. It's tempting to buy cheap LED's on ebay but there is a reason why they are cheap. Electrical items are not really the place to try and a save a few pennies. Buy from a reputable local wholesaler.

I've come across a whole bunch of LED bulbs sorry lamps that get hot too in varying degrees; I believe this is because of the design of a heat sink in the lamp base to draw away the heat from the led's.

And depending on who you chose to believe, LED manufactures have bases in the US, Europe as well as the Far East. So you could have US crap. :)
 
They all get hot, they take 5w and despite the relative efficiency of Leds the majority of the Electricity ends up as heat. So you've got several Watts coming out somewhere on the unit. If the fitting is enclosed it can cause the bulb to overheat and shorten the life of the electronics, but if it's open to the room then it should be ok.
The loosening thing shouldn't happen but it's a feature of Edison screw.

I've seen some with hot bases, the power supply was just a resistor (the hot part) and a diode.

Thinking about it...may have been better if we got the 3w version...I take it calling them bulbs is a no no.
