I have a bulb that uses 9 watts and a socket runs 7.5W-max is it still safe to use the bulbs this way?

Lower is OK, just gets less light.

Higher is bad - it depends on whether you are talking equivalent watts or actual watts.

An CFL or LED with actual 15Watts consumption but an output equivalent to 75W light bulb would be OK in a socket that said maximum rating 60W.

You can exceed the rating for equivalent watts but not actual watts.

If you exceed actual watts, e.g. an incandescent 75W bulb that uses a real 75W in a socket that says max 60W then you risk possible overheating and fire.

The bulb just won't run at full power is all.

Uhh, no. OP, I'd personally risk it but there is a chance that it will get too hot.

so, the 9 watt bulb will transfer 9 joules/sec of energy into light, your socket is made for bulbs that transfer 7.5 joules/sec of energy into light. the problem is it's not only light, it's also heat... just be careful that things don't get too hot. I would wait around, check the temperatures for a while before i deem it safe.

no. it will draw more current than the socket can handle. it will run for a while and then something will melt at a random time

I've used overwattage bulbs before without issue, but its a risk I took. OP, its close enough I personally wouldn't worry about it but its your call

This is what im using and after 20 min of running the olny thing that got hot was the bulb

i have seen other people do it. I have seen other people pay me good money to fix their broken appliance because they put the wrong bulb in. if it says 7.5W then that is quite a specific amount and i would stick to that. one hot summer day and your appliance will stop working

sorry to chinese people but I had to do this

You'll be fine with a CFL, the heat is so far away from the base compared to an incandescent lamp

i'd suggest you dont use that thing at all...

 

thats quite honestly the most dodgy "lamp plugged into a power socket" thing i've ever seen, and if that is actually considered even close to legal in the USA i fear for you guy's safety in general...

yes but you have not seen the fitting. this is a fancy lamp. the 7.5W rating might be related to the shade attached to it

No. The bulb may draw too much power, and risk starting a fire.

 

Most likely, the gauge of the power cable and wires are not rated to run more than 7.5W.

 

TL;DR, don't do it. Not worth the risk.

well.. now you say...

That fitting is designed for an e14 7w incandescent nightlight bulb. 

I'm surprised the bulb your using actually works. Fluorescent bulbs are funny buggers! 

It will get hot regardless of being underpowered. Touch the end of a strip tube and you'll know what I mean lol
