Definitely had a glass shade. What your looking for is a replacement with a neck so the lip sits on top of the screws. This site has a good selection but double check the diameter of the fitting: https://jmoncrieff.co.uk/John-Moncrieff-replacement-glass-light-shades/John-Moncrieff-clear-globe--with-neck-in-various--sizes- Ebay is a good source for replacement shades as well.

Hi Laurence, have you considered using recessed lighting uplights to shine up the wall. The reflected light will illuminate the whole room. I would suggest using high power LED Strip like our Samsung Strip, it is 1000 Lumens per Metre and draws just 8.2w of power. If you need it even brighter we have the 2000/m Lumen version. The effect uplighting will create will be less industrial looking than Corn Lamps. Feel free to call us if you would like to discuss further. 01624 819130 / 03333 222 008 Regards, Trevor www.litewave.co.uk

Dulux light and space paint are coloured already with special light reflecting articles. The paints are all light colours.

Hi, We would second linen shades. They are lightweight and thin, allowing a wide array of light to filter through. You could also try rattan shades these allow a large amount of light out through the gaps in the shades. Glass shades are also ideal and non of the light is filtered as it comes through the shade.
