It doesn't seem to work.Find a graph of diode characteristics you like and make a table of x,y co-ordinates of the curve at pertinent points.
Then visit this page and enter the co-ordinates. The result is a least-squares polynomial fit of the degree you choose; probably about 6-degree for a good diode fit. I've downloaded the page and run it locally.
Anyways, it's a bit off topic, so I'll drop the question.
I currently have 2 experiments in progress, with another completed.
Nothing really interesting from my 3 experiments.
1. I chopped up one of my failed old Christmas light strings and found that it was either a blown fuse or a single lamp failure, as the 5 bulbs I tested were ok.
2. I hooked up a string of 4 to my car battery, and although they draw almost exactly the same power, (73 mw AC/lamp vs 79 mw DC/lamp), the DC powered lamps are much brighter. The AC lamps have been on continuously since I bought them, approximately 10 years ago, yielding a lifespan of 88,000 hours. Since the entire string uses only 2.2 watts, I use them as night time navigation lights throughout my house. (There are 3 sets: 1 each for the kitchen, living room, and bathroom) Total annual cost: $7. My guess is that this may have extended the life of my remaining CFL's, as I almost never need to turn them on.
3. I assumed the string of 4 lamps hooked to my battery, being much brighter, were drawing more current, so I was going to leave them on until they failed. Though, I now know that isn't the case, and they will probably outlive me.
You have just been lucky I think - or else you have always bought top of the range versions.
I just checked 2 that are easily accessible and they are both made by "FEIT Electric".
I think I did get the high end one: $8.21 at Amazon (FEIT Model # BPAG500DM)
a 10 pack for $13 at the local hardware store (FEIT Model # A800/830/10KLED/10)
