Hi all, Complete lighting/electrics newbie here, I have a pull on/off light in my cupboard that has stopped working. I think I accidentally knocked it one day but only lightly. I have bought a new lightbulb for it ([url=https://www.amazon.co.uk/gp/product/B01CK4EMAM/ref=ppx_yo_dt_b_asin_title_o04_s01?ie=UTF8&psc=1]https://www.amazon.co.uk/gp/product/B01CK4EMAM/ref=ppx_yo_dt_b_asin_title_o04_s01?ie=UTF8&psc=1[/url]) but it doesn't work so I don't think it's the bulb. In order to fix the fitting and/or replace with a new light fitting, what would I need / need to do? Photo attached and thanks for any help you can provide.

We bought a table lamp that came with a 9 watt LED Bulb. The bulb has the same shape as a regular incandescent bulb but it has a plastic skirt abound the lower half of the bulb, The skirt effectively blocks most light that would shine out the bottom of the lampshade. There is a sticker on the lamp socket that says use only 100 watt max type A bulb or 9 watt max LED bulb. Why is the LED type bulb limited to only 9 watts. It really puts out insufficient light, I put in a 100 watt GE bulb that puts out about the right amount of light. I would like to switch to an LED bulb that provides better light but not sure if higher wattage is safe. Do they all have a skirt around the bottom that blocks light?
