Painted Glass Block Landscape Lights (was Glass Drill Bits)
A few weeks ago there was a thread about glass drill bits. I
mentioned I was working on making glass block walkway lights. One is finished. Here are the details: http://www.kissingfrogs.tv/blocklights.html Steve J. Noll | Ventura California | Glass Block Pond http://www.kissingfrogs.tv | Fused Glass/Brick Wall http://www.peltier-info.com/wall.html |
Good project and excellent report with good details and images.
Minor point - cutting the voltage in half will cut the wattage to a fourth, you are feeding 12.5 watts to each bulb. Your statement that the bulbs will last a long time is extremely correct - thousands of hours. -- Mike Firth Hot Glass Bits Furnace Working Website http://users.ticnet.com/mikefirth/hotbit46.htm Latest notes "Steve J.

I can't belived I missed that! I just finished some testing,
measuring current consumption and optical power output and found it actually reduces the wattage to about 1/3. The difference is probably due to the filament not being a fixed resistance but varying with temperature, plus the peak voltage and current are not different - they're just occuring half of the time periods as before. The diode Vf is almost not worth considering. Anyway, not really worth setting up a calorimeter for...
