CFL Warming Shade

This Instructable shows you how to make a lampshade that will not only warm the light from a fluorescent bulb but also provides an aesthetic of porcelain. This shade can be used on its own or with your existing shades and is ridiculously easy to make, all you need is a white plastic bottle (usually HDPE bottles used for milkshakes such as Yazoo and Frijj.

This is another design that forms part of my final year Product Design Degree project based on democratising design so lets see what variations can be made and then send them to me to be displayed at my grad show in London! More details at my Blog Design Democracy

Step 1 Parts and Materials

For this product you will simply need a white HDPE bottle and a sharp kinfe

Very nice, I really like how it creates shadows with the grooves of the bottle.

Seems a bit orange in the picture, is that how it appears or was it just a white balance issue with the photo? How much light are you removing by putting this on the light?

The shade appears much whiter, almost exactly like porcelain, but I am neither a particularly good photographer, nor no I have a particularly good camera so it has come out more orange than in reality, any tips for sorting this? On the amount of light it cuts out point, I think there is a small amount lost but, for me at least, I'd rather have ever so slightly less light in exchange for losing that cold, harsh glare of fluorescent light.

White balance should solve it, but when phtographing lights, that tends to make them actual white in the photo, so it can pay to whitebalance off some daylight on a white card and then photograph the light, or set it to daylight. That amount of orange is something I would expect from an incandesent rather then a fluorescent, so I am guessing that the white balance on the camera was manually set when it was looking at something quite blue in the past.

It's a diffuser that cuts our the high-energy end of the spectrum? Simple and effective. (nice) L
