Just new here and dont know where to post questions. I need direction on how to construct a 40w chokeless flourescent lamp. I need this like hell. If you can spare me your time, just mail the solution to me. I am running an assignment. Let me not freak you out to ask for a summary of the processes involved.

Cool stuff! Works better than ever!

Have you tried Google? Or even looking on the circuits page on this website?

Yeah, but cant find exactly what. Not tried it without a choke before. Thanks for your concern. Still searching.

Some way to step up the voltage is necessary, so a choke or transformer is going to be the way to do it.

I could finally try the 40watts fluorescent project. The source: http://www.talkingelectronics.com/projects/FluorescentInverter/FluorescentInverter.html
however i used 2N3055 and 104n capacitor. Exact specification on parts not found in my area. The tube came on instantly on test. The brightness was fair as a result of old battery used. It is a good project. The transistor never heated a bit. I was amazed at it. No heat sink was used. I guess this could be as a result of the transistor used which withstands higher power.
However I have tried to reconcile the project with mathematical calculation. Project is selfcontradictory with my calculation. Does anyone have a clue on how to do the stage-to-stage calculation on this project, or even a brief mathematical summary?
I will be glad to hear from you all. Thanks.
