Pwede naman yung regular na fluorescent lamp di pa delikado sa mata.

Ganito bili ka na lang ng regular lamp mga tatlo tapos yung na save mo gawa ng timer for exposure or you can use your alarm clock or you cell phone's count down timer for an even more savings. 

Try this http://www.electronicslab.ph/forum/index.php?topic=348.0

Syempre pag naka save ka papaburger ka hehehehe

No problemo...welcome na welcome. 

It doesn't matter kung electronic or regular ballast gamitin mo, mas matipid nga lang kuryente yung electronic and mas magaan.

Kung box naman problema, pwede ka gumamit ng sirang scanner para sa casing ng exposure box mo, post ko pix nung ginawa ko, nakuha ko lang sa net yung idea.   Pwede rin yung wooden box.

Ayan dami mo na savings....pa burger ka na!!!
