The hoopla over LEDs has led me to do a little test. I made myself a reading light
for the Burro
. Fun with the table saw. Bought an 1156 base and screwed it in my little wooden wall fixture. Now, I waited for my 24 diode white LED, $15 plus shipping from an internet supplier, to arrive. It's the largest bulb I could find that was also small enough to serve in my neat little home-boy fixture.
When it arrived I couldn't believe how truly small that LED was. Not quite an inch in diameter across its face. I plugged it in and switched on the juice. First of all, to me, the light
seemed hard, harsh, cold, and bluish. But to my surprise it also did not seem bright enough, at least not for reading a book.
This called for comparisons, a test. Which is brighter? I went out and bought a Halogen 50 Watt bulb in an 1156 base from the auto supply store. I put each bulb in the fixture and photographed the results, a furry animal. Digital cameras are great for getting instant results, aren't they?
I first shot a picture with the LED bulb and the camera on Program mode. I noted the settings my camera chose, and used those settings with the camera now in manual mode to shoot the second picture with the Halogen bulb. My findings are that the Halogen bulb is roughly FOUR stops more bright
than the LED. The Halogen was also slightly warmer light.
I will be using the Halogen bulb in my reading light (...if it gets installed at all, that is. Was fun to make, but sooo ugly!)
