I recommend LSDiodes (http://www.lsdiodes.com/). Very reasonable prices. And last I checked, you get a free "Robots will kill you" sticker .
Where online can I buy some high light output LED's.
What type of LEDs should I go for?
I'm trying to replace my interior halogen bulbs (vanity, reading, floorwell lights) with some white LEDs.
Either sflux or 5mm? What do you think?
What colour(s) are you looking for? (certain packages are better for different colours).
edit, sorry, just read - white!
In that case I would go for 5mm. unless you want really bright, then consider the Luxeon Star range.
Also, what mcd rating should I go for, for these interior lights?
They shoulnd't be obnoxiously bright.
To be comparable with a standard interior lighting bulb, you will need approximately 20-30 candelas of light output (20000 to 30000 mcd).
L/R Vanity mirror bulbs about 6000mcd each
Floorwell is dependent on your personal preference I guess, but I would say around 15000.
Would a triangle cluster of 3, or a square cluster of 4 10k mcd 5mms look cool?
Should they be tightly packed together or spread out? Currently, there's a translucent plastic cover over the halogen bulbs that diffuses the light slightly.
What are sflux LEDs used for?
Would a larger patch of lower mcd LEDs look nicer than a smaller patch of high mcd LEDs?
It really depends where they are going to be used. A couple of photos of your car lighting would be very useful.Originally Posted by phita23
Sflux is an abbrevitaion of Superflux which is the name given by Lumileds to their 4 pin square LED package.
they are most commonly used in high intensity car brake lights, but are electrically the same as white LEDs though are able to handle slightly more power.
A tight cluster of white LEDs would be fine, and you really want the widest viewing angle you can for your requirements.
Ok Let me go take some pictures now. be right back
