K-Line Rotating Beacon ??

More Voltage Power !

per Tim the Toolman.

More voltage equals more heat and hot air.

I thought of that Tim.  How many volts can these bulbs take ?

18V

Don, I've done two do-it-yourself tricks to make those dimple-bulb type of rotating beacons work better.

One is to affix a small DC motor somewhere near the top of the beacon tower. The motor when it is on will create some vibration on the tower and will cause the beacon top piece to slowly being to rotate, regardless of bulb voltage.

The other way, which I have read others also do, is to hide a brushless computer hard drive fan in the vicinity of the beacon tower, aimed at the tower. Again, the beacon top will rotate regardless of the bulb voltage. Of course, here the distance of the fan to the tower will determine how fast that beacon top will rotate.

I've also made my own dimple bulbs by heating a bulb over the gas jet on the stove. This is something of an acquired skill, as it is also not impossible to really distort the shape of the bulb. It didn't take me long to get it mastered, so I can use lower voltage bulbs that match the other bulbs I have on my secondary power.

This year for the Christmas putz I bought an inexpensive aquarium air pump and ran clear plastic tubing up into the tower with a fashioned(from a vacuum hose barb) orifice at the tip. It powered up with the transformers, as soon as power came on it started rotating.  In addition to arranging the position, distance, & aim of the tube in the tower, the pump also come with a small metering valve for fine tuning. The results were fantastic, I turned the bulb power down to a comfortable level for appearance, and did not have to break into my spares. The pump tubing can be T'ed off for use in several towers as needed.

I "enhanced" one of these with a very small blower and a soda straw directing the air into the head, I had to restrict the airflow by slowing the fan way down, even though the straw was a very small diameter.  It doesn't take much air to spin these.

Thanks.  All sound like good solutions.
