Fisher Posted March 20, 2012 Report Share Posted March 20, 2012 Seems I'm suffering the ill effects of my 15 year hiatus. I picked up an older Coralife dual fixture that I reckoned was T5HO. But it's a 1/2" shorter than a T5 tube. The socket looks like it takes a small square nib over against two pins. Ring a bell with the sw community?

jewels Posted March 20, 2012 Report Share Posted March 20, 2012 The VHO moniker is typically applied to T12 linear fluorescent lamps. The bulb to fit your fixture is better known as PC or power compact. They are becoming obselete as they are overshadowed (har, har) by T5 HO. Allegedly PC's run hot and by virtue of their shape do not get along well with reflectors. If the ballast is electronic (as opposed to magnetic) you may fire a T5HO with retrofit tombstones.

Fisher Posted March 22, 2012 Author Report Share Posted March 22, 2012 Ok. I read that VHO=T12 before, now that you mention it. But I checked out when I saw T12. I'm paying attention now. I've heard/read people using PC and CFL (2G11) interchangeably... and CFL, referring to the little spiral fluorescents that screw into incandescent sockets. Sometimes the colloquial use of the terms makes them enigmatic. Thankfully, that hasn't happened to toilet paper. The fixture is really light weight; it has a ~22ga wire on both sides of the frame that slide out to suspend the fixture - I reckon my Hagen Glos are ~12ga. I assume I'll have to rip the fixture apart to change the tombstones anyways. How will I know if the ballast is electronic? Is weight any indication? BTW: I miss your other avatar jewels Quote Link to comment Share on other sites More sharing options...
jewels Posted March 23, 2012 Report Share Posted March 23, 2012 . How will I know if the ballast is electronic? Is weight any indication? Yes the weight will give it away. Electronic are nearly weightless. Tar ballasts are , , ,well ,, ,full of tar. BTW: I miss your other avatar jewels Better than 1969 Miss Nebraska beef ?

Fisher Posted March 24, 2012 Author Report Share Posted March 24, 2012 I'm a corn-husker jewels. My family moved up here the year this gal smiled for the camera. I liked your other avatar because it didn't make me hungry for corn-fed prime rib and Nebraska sweet... Quote Link to comment Share on other sites More sharing options...
