Picture of Soft-Box Photography Light
I decided to make some soft-box lights for our photography setup in our studio. 

The aim of a soft-box light is to create an even and diffuse light source, is is simply an enclosure around a bulb comprising of reflective side and back walls and a diffusing material at the front of the light.

For my soft-box lights I used some energy efficient dimmable daylight bulbs so that they do not get too hot but output a good amount of light, but also so they can be dimmed to adjust the light levels.

The materials for the whole project are, 

- 4 x Energy Efficient (Compact Fluorescent) Daylight Dimmable 20W Lightbulbs
- 4 x Light fittings for the bulbs, as i'm in the UK i am using BC (Bayonet) Fittings
- Mains Electrical Cable
- Mains Plug
- Dimmer Switch
- Backing box for dimmer switch
- Small bit of wood, size is up to you, it needs to be big enough to fit the light fittings on it 
- Flat Screen TV wall Mount
- Card Board
- Tin Foil
- Tracing Paper
- Screws 
- Sticky cable tie mounts
- Rubber bands
- Tape
- Double Sided Tape

Various Tools

- Screwdriver
- Drill
- Snips
- Wire Strippers
- Knife
- Screws
- Saw

I'm using 4 light fittings to get a good amount of light, but you could just use one if you wanted. 

If you're using more than one fitting, make sure to wire them in parallel so they daisy chain together.  In order to do this you will have to wire in two wires together into 3 of the fittings. 

The fittings I am using have a mounting 'skirt' which needed trimming so that when they are attached to the wooden board they sit flat. 

Before you screw them to the board it is a good idea to check they are all connected together using a Multimeter.

Thanks so much! I think this is just the type of setup I've been looking for, I'll try making a couple of these this week and see how it goes
Last night, I was trying to find the "Sweet spot" Apperature setting for my lens's I set up 2 100 watt light bulbs that fit in the aluminum shades (the lights used for reptiles and such) but with a standard 100 watt bulb in each.... I quickly found that It just isnt enough light and that I needed something much more powerful! I ABSOLUTELY LOVE THIS IDEA! I will be making at least two of these guys. Thank you again for posting this one! GREAT JOB!

How warm do they get?

They get slightly warm, but you can still touch them not not so hot that they burn. I found that in a smaller reflector they get warmer as there is less air space.
Great, my next to-do, thanks for sharing.
Awesome Instructable! I'll add this to my "to make" list. Thanks for sharing!
