Introduction: Accent Light, for Photography
This instructable will guide you through making an accent light, i use mine for photography.
This is my first Instructable, so I hope its clear and concise enough for you all, I hope it helps you all too.
Requirements: What I wanted to achieve was colour accents in some of my pictures, either in the background or just a stream of light entering the picture, I have an old 4 channel light chaser laying about, and an old 4 way dimmer switch, so I thought Id try and solve my problems using this. If you dont already have a chaser you can pick them up very cheaply on eBay, you could always pick one up from a boot-fair, wouldnt be that expensive, and doesnt matter if it doesnt work either, as long as it has the bulb holders.
First of all, you will need to make sure you have:
4 Channel Light Chaser;
Plasterboard back box;
4 way dimmer switch;
Bulbs, if you dont already have them.
An angle grinder will save your arms, and time, (I used one of these) however a saw would be fine,
An electrical screwdriver,
And whatever screw driver you need to dismantle the chaser (mine was a No.2 Phillips)
Step 1: Rip It Open
First of all you need to strip down the box, remove all of the insides, including the circuit boards, and cables, remove all the bulbs and then remove the bulb holders inside.
Step 2: CUT It
The next step is to take your back-box, and mark the back of the unit, I wanted this on the top, but the bulb holders got in the way so the back it was! One you have marked this out you will need to cut the unit so that the holder fits inside the unit, make sure you allow space for the lip on the lid, otherwise youll need to re-cut later.
Step 3: BEGIN Building
Once you have removed the part where the switch will go you can put in the back box, and your power cable, I managed to use the same strain relieve that was there previously, you may have to purchase a new one.
Step 4: Connect the Cables
You can now need to connect your cables to the bulb holders, I used a common for the neutral, so they were daisy chained, and then a common live to the switch which was again daisy chained across the switches, then each holder has its own live feed from each dimmer, this means that I can dim each channel individually, dont forget to add the earth cable to the case of the unit!
As you can see from the pictures its a very simple wiring job but as this is mains electric if you do not feel comfortable or youre not confident, please consult an electrician, if you are confident and you wish to use this outside your home you will have to get this PAT tested (Portable Appliance Testing) please make you sure you do this any way to protect yourself and others.
Step 5: CLOSE It, TEST It, USE It!
Once you have connected the cables to the bulb holders you can put the holders back in the case, and prepare the wiring so that it is ready for your switch, connect up all your cables, and begin re-assembling you unit, you may want to test them at this point, so you dont have to open the unit again. I didnt I would advise using a multi meter to make sure there are no shorts!!! One you have done this you can simply put the unit back together and there you have it, put you bulbs in and you have an accent light!
As you can see my son decided my son wanted to check them out!
Something worth considering is this could be run off a 12v inverter, so as long as you do not draw more than your inverter can supply you can use this out and about with your car.
Hope you enjoyed and this is easy enough to read and follow.
EDIT: I have taken a few demo shots of my son's Yellow beaker, hope you like
