To the person who posted the question to me, David has replied that the LEDs are in high demand. We will be installing them around the time of the Supernats. It was my interperetation that they will remain there....but then again....my interperetation.

hey with the brighter lights, we should start racing in other weather conditions- whether snow, sleet or rain. and hey oil downs will be more obvious on snow! :lol:
I'm sorry, I had to let one bad joke go for the day... lol
I've been telling David we should open a hovercraft class, 'specially after the beginning of last season. We were about to start making sure we weren't located on an Indian burial ground...hehe.

The theory of LED sounds okay, more consistent brightness in various lighting conditions, they dont burn out from vibrations and they illuminate faster. The problem I see with NHRA is they drop them on the teams the opening weekend and realize they improve reaction times .03-.05 so the teams have to adjust for them. Then they turn around last week in Phoenix and put a .03 delay on the LED's so the teams have to adjust again!
Also, I believe there is more than just a bulb change. The flood light is 110v filiment the LED's are a cluster of low voltage (light emmiting diodes) so there are some wiring and step down transformers involved.
I dont mind the change as long as we time to adjust to the change.
I Believe that it is just a bulb change. They (NHRA) said that very soon you will be able to purchase these bulbs for your porta-tree if you got one.. :thumbs:
During one of the "down times" at Phoenix last week there was a short explanation of the bulb issue. The "sample" bulb they had was an improvement from the ones used at Pamona. They showed it had a small unit like a transformer on the back so when it was screwed in it would illuminate. They did not say that you needed special electronics or anything else, just this bulb and go. In the transformer (or whatever name you want to give it) was the electronics for the time delay of the LED's, and that is why they could adjust the time of it, and why you allegedly did not need special electronics to light it. Or so the story goes......
The flood light is 110v filiment the LED's are a cluster of low voltage (light emmiting diodes) so there are some wiring and step down transformers involved.
Actually, no stepdown needed with the right electronics. The company I work for has a line of LED operator devices that operate on 85-264 VAC, and last for a LOT longer than incandescent. Check them out on the website, www.moellerusa.net and look at the "Titan" line of operator devices. We use them in the custom controls we design as well as sale to the public. These are single LED units but I'm sure it would not take much to put an array together without the transformer.
The LEDs are custom made by Bob Brockmeyer at Compulink. There are a total of 39 LEDs in one bulb. They will be used at HRP this weekend for the division 4 event. According to Graham Light, if the red-lights continue, they will do something with the electronics to slow down the illumination time. See National Dragster, February 28 issue, page 28.l
