I am very interested in those Luxeon Star LED's. I've never used one before, but I've read some very interesting things about them, and I am thinking about using one in my project.
I have a few questions about them (info which I can't seem to find on the net):1) For those of you who have used one, are they worthwhile? Are they really that bright?
2) I currently have a high brightness white 12-LED Globe from Jaycar Electronics (see link).The brightness of this LED globe is quite good, but I want brighter! How would the brightness level of this compare to a 1W, 3W and 5W Luxeon? I am only used to "MCD" type measurements, not "lumens" per watt. The Silicon Chip website shows two projects where luxeons are used outdoors at night... Surely they can't be *that* bright?! 3) If I was wanting to power up a 3W or 5W Luxeon Star, what would be the most *simple* power supply I can connect to it that would fit nicely into a UB5 Jiffy Box (83L x 54W x 31D mm) - including the luxeon heatsink? I've seen some luxeon drivers around on the web but they seem too big in size for my project, probably because they include special functions like low battery drain, low power cut-off, brightness control, etc (features I don't need which take up board space right?).. Note that I will be connecting a *12V power adaptor* to it (as opposed to a battery), so I won't need most of those features. The smaller the driver circuit, the better =) Any ideas?
Thanks in advance,
