NERD ALERT Pure Electronics Question
I want to use 78xx voltage regulators in my 36 volt lighting. To power integral with heatsink 1 watt fans. Clarification: I purchased new surplus PC obsolete heatsinks with ball bearing fans for less ...

Circuit board + LM317 + heatsink + resistor + cap
Tough to come in under a dollar. If that @#$%&! heat sink came out to be 1/8" shorter I could do it but standard TO220 sinks are fat and skinny (black anodized) heat sinks cost almost two dollars then require potting material.
Thanks for your help sir, I am going to try the eBay switcher!
I also have a small box of TO247 adj regs rated for 10-amperes. They are fun to play with. I only wish they could be configured (manufactured designed) to use Silicon Dioxide MOSFETs
Can't have everything but boy you sure solved my dilemma. I am a happy camper. I was looking at switchers but finding only those with 30 volt upper limit.
