Remember
project #2 that I mentioned last week? Well the ceiling light I ordered arrived on Monday. After a quick check to make sure the inner workings were set up properly for my lighting hack I set about measuring, calculating, and internet surfing to find the best deal on the many, many beads I'll need.
It turns out that calculating how many beads in each size I need was more involved than I originally anticipated. First I had to get a general idea of how big I wanted my largest beads to be; then I quickly found that limited size selection and pricing would play a big roll in the process. After several rounds of searching I found a good starting size. From there I dusted off the semi-upper level math section of my brain and started thinking all hemispherically.

The circumference of the light (96 cm) and initial bead width (1.2 cm) were used to calculate how many strands I'd need (I estimate 50), and a quick measurement of my light told me my strands would need to be 19 cm long. Now that I knew my strand length and height of the first bead I could just add on the height of beads which will steadily decrease in size (so that my strands form smaller and smaller concentric circles as they reach the bottom of the light) until the strand reached 19cm in length.
I don't care what any of those math-haters say; math is fun and cool! Or maybe I'm just a dork. Either way applied mathematics is totally my idea of a good time.
But how many beads does this add up to exactly? 1,250 beads.
That's a lot of beads.
And I actually had to order more than that since beads come in 15 inch strands. So at some point a little over 1,400 beads will be arriving on my doorstep.
Of course I've done all this yammering about bead calculations but left you in the dark as to what type of beads I ordered. Well the chandelier that inspired my lighting project is made up of turquoise, and that's the look I really wanted for mine as well. But 1,400 real turquoise beads come with a price tag to match, and I am beginning to see why this chandelier is priced at $3,780.
That's hundreds of dollars worth of turquoise just hanging from a ceiling! At any rate I wasn't about to pony up a couple hundred dollars for turquoise on this project. I opted for imitation turquoise instead and got my beads for about $50 with shipping costs. The beads actually cost more than the light fixture itself, which was only $30.
When all this knock-off turquoise arrives you'll surely hear about it, along with pictures of the light making process. In the meantime I'll be watching for the UPS man!
