Try it and see if anything gets overly warm. Bedside lamps don't tend to get used for extended periods, although 7W might be a bit bright for waking up to.

I've put it in, actually it's OK to wake up to as the bulb takes a little while to warm up and reach peak light, which is good whilst my eyes adjust. It's not exactly spotlight even when at full brightness!  Can't imagine a 4w bulb being very bright. It's not getting particularly warm, nothing like the old incandescent, but it is emitting a bit of a hum.

Looking online, I could only find 4.2w bulbs, not 4w, so even then it would technically be overloaded!

Look on the very same page as the link you provided, 2 4w bulbs for £8.

These are 470 lumens, which is roughly equivalent to 40W incandescent bulbs (and your 7w cfl bulb).

Think of all that electricity you'll save over the years

I didn't notice the label in the shop which is a 36 mile round trip from me, so I'm not going back to buy bulbs.

The £8 saving I get not buying the bulbs will buy a fair bit of electric at 6w per pair. Plus we have solar panels and batteries so I'm not overly worried about the cost of the small amount of electric.

In the old days bulbs could get hot enough to start a fire/melt wiring but nowadays that's not really an issue

Have you got a link for these lamps?

LED bulbs should not take time to warm up they are instant on , are you using the old style cfl bulbs? 

Personally I wouldn't hesitate sticking in a 7w LED in there as an extra 3 Watts will make diddly squat difference to anything 

The bulbs are indeed cfl ones we've had lying around for a number of years. Can't remember what we bought them for.

This is the lamp.

You will be fine using a 7w LED in that fitting , you could stick a 40w old style bulb in there and you will be fine 

Plenty of room for ventilation and the lampshade will be fire proof too.

Would love to know how they decided on a maximum 4 watts

Are you sure it says don't use higher than a 4w bulbs? Dunelm recommends a 4w es candle bulb but that's just a recommendation 

Here's the label.

Still surprised you could not find 4w E14 online

Ah made in China,  therefore somebody has probably translated the manufacturers instructions from Chinese to English,  back to Chinese then back to English!

You will probably find they meant maximum 40 watt bulb but in the poor translation somehow lost the zero

@cerebus a 40 W mini globe LED would be blinding !

TBH I only looked at Screwfix and Toolstation as they are local to me, then I found the 7w ones in our garage and stopped looking.

Seeing as the lamp holder is designed for an LED bulb, using a compact fluorescent or incandescent bulb will produce more heat than expected.

It's really not hot at all. I can easily hold my hand above the bulb.

it's not possible for a manufacturer to make a light fitting that will work with a 4W bulb but not be capable of working with a 7W bulb.
if you were to work out the minimum CSA of a cable capable of dealing with a whole 4W it's going to be about 0.0017mm² , that size of cable is impossible to manufacture.
a typical small conductor used in light fittings is going to be about 0.5mm² which in theory should be able to carry over 1Kw
