My son recently moved from our house, where we were paying approx $500 a quarter, to his own home where his first quarter bill was over $1200 - we have solar. I think Oz has the most expensive power anywhere.

The talk of oscilloscopes and logic analysers below has activated my geeky electronics gene, so I'll share with you my thoughts on some RGBW ribbon that arrived yesterday and I dutifully wired up. This stuff:
We're modernising our bathroom and have opted for profile lighting recessed into a multi-layer ceiling. Why does someone need multicolour lighting in their bathroom - good question, but if going down the profile and led tape route why not?
Anyway, it's brilliant. The white light you get from mixing R G and B together isn't that good for illumination apparently, so the 4th white LED is included to address that and what it means is that the ribbon can produce various shades and tints of white (so called, warm, cool, natural etc.) and it really seems to be able to produce pretty much any colour you want.
This tape is expensive. I've bought similar products direct from China in the past but I believe this is a case of you get what you pay for. Consistent colour and brightness (something which becomes noticeable as you dim the things), and the 24v rather than 12v helps to keep the light uniform over longer lengths. Oh, and it's bright. We have about 8metres of pure warm white 14w/M ribbon in another room, and turning it up is like being in a TV studio. Not that I've ever been in one.
I'm sold, but my advice if you are considering something similar is skip the cheap stuff you find on Amazon and ebay and go for quality.
maybe quality is the way to go, but those things (mostly cheap) are turning up everywhere
my new motherboard has led strips (turned off), even ram chips have it for an extra dollar (why?). I built my latest rig to be as tiny and unobtrusive as possible. I've seen advertised bicycle spokes with them that such that if you ride fast enough (not that fast) looked like they could render images visible from the side.
soon everything's gonna be led stripped!
Holy sh*t!! take cover!! there's humboldt squid attacking people in the park!
... don't be silly, it's just the neighborhood dogs playing frisbee with their owners.
An interesting read on how white light is created with LED's. It sounds like your white light is the blue-yellow combination. However, that link is from 2003. Still, reading the wikipedia link, it seems that's still how it's done.
