Contemporary Wall Lights

Low energy contemporary wall lights for Ledbury Passivhaus

New design

Certified Passivhaus

Ruth borrows our battery drill to fit her plaque.

Colin Chetwood and I have experimented with various options for low energy wall lights over the years including the mirror lights developed for Architype’s Hereford office. We also designed optimised timber pelmet lights for a housing development in Oxfordshire. What we didn’t have was a good economical solution for  basic wall lights using standard CFL or mains voltage LED lamps.


Customisable shade

After a good amount of experimentation we have designed a very simple solution that can be adapted for a wide range of applications. Our first installation uses shades with Japanese paper made from mulberry leaves. This looks very Zen but kid’s art and colourful abstract drawings are equally suitable. The paper or art work is sandwiched between two polycarbonate sheets and simply clipped into the backplate. The fitting is designed to minimise the chance of seeing the tube even when installed on a stairwell. The generous form allows plenty of light onto the wall and ceiling. The shade density can be chosen to adjust the amount of light bleeding through.

Mike Whiffield who built the Ledbury Passivhaus has since ordered wall lights for his own recently completed Passivhaus. These have been supplied with integral pull switches to allow additional control.

The wall light is manufactured in the UK by Colin Chetwood. For contact details see our collaborative website There is an A4 and an A3 version and custom models are possible.

Lock Lamp

LED Lock LampIt is great fun making things with Colin Chetwood and we are always looking for excuses to create things together. Our latest project, Lock Lamp was inspired by the G4 LED modules recently fitted to our cooker hood and an ingenious positionable lamp mechanism developed by Colin.

I do have a weakness for classic desk lamps and have a small collection acquired from car boot sales and even the Council tip where I picked up a lovely Hadrill and Horstmann Counterpoised Lamp for a pound (I didn’t know what it was until I Googled it just now!). This is a brilliant springless design but not balanced for energy efficient lightbulbs which weigh more than old GLS bulbs. We also have quite a collection of old machine lamps that would have once adorned lathes and milling machines in the days when we manufactured things.

However none of these classic lamps quite met our needs so we decided to make something that did.

We are already working on the next two designs, again driven by a need for a product we have not been able to buy, watch this space!
