esantoro Posted March 22, 2009 Report Posted March 22, 2009 I've ordered the following LED lights to be used to put more white light on top of my machine's needle. I'm going to try to connect them to a 12volt 300ma wall wart transformer. If it works, I will figure out how to put an on/off switch in the middle somewhere. http://www.ledwholesalers.com/store/index....p;productId=277 http://www.ledwholesalers.com/store/index....p;productId=349 http://www.ledwholesalers.com/store/index....p;productId=279 ed Quote http://www.waldenbags.com http://www.waldenbags.etsy.com
Members skipj Posted March 23, 2009 Members Report Posted March 23, 2009 Might find this helpful they say it can be used as a task light. You have the stuff, but this might give you some ideas about resistors and heat sinks. SkipJ Quote

Skip, did you have a link in your post? Ed Quote http://www.waldenbags.com http://www.waldenbags.etsy.com

esantoro Posted March 23, 2009 Author Report Posted March 23, 2009 This might save you some time, Artisan sells them.Kevin I have those lights from Artisan. They work well. And Artisan has been very good to me regarding those lights. I've realized you can't have too much light above the needle and am under the impression that the LEDs from LEDWholesalers are five-times brighter than regular LEDs. I'll find out when I receive these and will report back. I'll have to figure out a 12v adapter to run these LEDs. Ed Quote http://www.waldenbags.com http://www.waldenbags.etsy.com

esantoro Posted March 23, 2009 Author Report Posted March 23, 2009 Thanks Skip. Cool links. Word from LEDWholesalers is that their bright LEDs don't crequire a heat sink. The Luxeons and CREEs do. That one 1watt luxeon bulb is 90 lumens. Four or six of the SMT bulbs in arrangement are equivalent to about 90 lumens. I'd like to find a source for the individual bulbs and start making my own circuit boards. Ed Quote http://www.waldenbags.com http://www.waldenbags.etsy.com
gtwister09 Posted March 23, 2009 Report Posted March 23, 2009 Ed, Looking forward to hearing back from you on your latest foray into the LED world. Regards, Ben Quote
Suze Posted March 23, 2009 Report Posted March 23, 2009 I used to use 12 volt transformers in the dollhouse world - try looking there or in the slot car stuff - I found some there too. don't know if they were 300ma or not Quote Reality is for people who lack imagination Whether you think you can or think you can't - you are right. ~Henry Ford
