1Ponders,Had a look at the page and yes it shows it in series but if this is the case and if you want the globes at full brilliance the you will need the higher voltage and high current.Leds may be the answer, but some of the fancy high intenity LED's need PWM power supplies.I am also not deliberatly typing in one line that is how it is posting it for some reason.??????regards.
I had to duck out last night as we had guests. Like you, I am somewhat electronically and electrically challenged, so I tread very carefully and ask lots of questions.
My original design for the C9.25 used low voltage torch bulbs (3V) and I wired them in series so that I could use a 12V mains adapter. This is why I didn't choose 6V or 12V bulbs.
I did think of putting them in parallel, and this would have required a 3V adapter but the current draw would have been 4A as the torch bulbs are rated at 1A each.
It's all together now. Just have to fix the top on properly once I decide on the bulbs I'm going to use. Boy it's bright and yellowey red/pink when turned on. This was taken with the DSLR and I have no idea where the white balance was when I took it. In real life it looks much less pink. I wonder where Eddie got the ultra white halogens from?
I've run the light meter over it and checked the colour channel info in Photoshop and it looks pretty even with no more than a couple of fractions of a % variance over the whole surface. Very happy.
Oh and the last 2 shots are the info from File Viewer of the Raw info and capture details and the colour histogram in Photoshop.
The lids only just taped on atm until I find a whiter bulb and the cuttin' she's a bit rough around the hole, but she's snug on the 8" and nice and light. I'll tell you though I wouldn't want to turn it on and then forget about it, it gets hot pretty quick. I took about 20 shots with the canon at various exposures and I could feel the heat through the core fill by the end of about 2 minutes.

Hi Paul
That is why I chose low wattage torch bulbs and am now looking at LED's. The flats look good, just watch the heat eh.
I'll let you know how I get on with the LED project.
