Determining Maximum Wattage for LED Bulb in Specific Lamp Holder

Good morning,

What the sign below says. At what maximum power can I screw the LED bulb into the holder? 9W or 60W?

On the E14 thread you will not find a LED light source with a power greater than 6-7W, so there is nothing to think about here. greetings

E27 is a thread I see light bulbs 15W http://www.ceneo.pl/29358117#mh=q6P6sCUW50004...5L1Z8Wbr1Qc-HglywsnkX3CaaU9UYdOaOUmerhs9_Ggs0

How can you increase the power? Replace the bulb holder?

I suppose that the information contained here results mainly from the LUMINOUS FLUX produced by the light source used here: a 9W compact fluorescent lamp gives +/- as much light (~ 600lm) as a 60W tungsten bulb. A similar amount of light will be provided by a 6W "warm white" LED lamp. Such a limitation is obvious, for example in desk lamps, in order to avoid glare.

In some luminaires, the limitation of the light source power results from the thermal resistance of the materials used to build the luminaire, then, for example, the permissible power of 60W applies to any light source that produces heat.

In my opinion, it is about the heat resistance of the frame.
"Traditional" light bulbs generate significant amounts of heat when lit - as probably everyone knows.
A similar situation also applies to compact fluorescent lamps, but in this case the light-emitting element and the electronic components inside the housing heats up.

There is no description of LED bulbs on the plate because the heat emission in these light sources is relatively low.
In my opinion, you can even install a much more powerful LED bulb than the ones proposed above - of course as needed.

I don't know what the maximum power LEDs are currently producing, the maximum I found is 36W
