Ballast from SADelite lamp (Robertson Transformer Company)

Ballast from SADelite lamp (Robertson Transformer Company)

Click to view full size image

This is the ballast from the 'new' lamp I bought on eBay.

I am unaffected by SAD but I do like interesting lamps & fixtures. This one has an all metal body unlike the Verilux one I used to have, which was plastic

I am using the old tubes that I had laying around from Verilux which are almost EOL but still work.

Welp, curiosity got the best of me, so since I couldn't open up my Sadelite desk lamp to check the ballast inside it,
I got my old Nokia Lumia 1320 phone and used the flash light app on it. I shined the light through one of the holes, peaked through another hole
within the desk lamp, and... the ballast is absolutely NOT the same as the ballast in your Sadelite. It's one of those no case/completely
naked type of electronic ballasts... no tar... nothing. Just microchip based..., exposed capacitors, two microchip
ballasts, etc. Cheapo... so it looks like in order for me to convert this to the Rapid Start ballasts we both know,
I've got a long way to go. Even the wires protruding from this microchip is different from a Rapid Start ballast diagram...
2 yellows along side 2 reds on one side, and 2 yellows along side two blues on the other side.

Can you post a picture of the inside? Why can't you get inside yours?

@Fluorescent05, I can't get to the ballast yet since I have no tools to take out the screws.
@LampLover, the link you provided... it looks as if the ballast in my desk lamp is indeed... a Type A ballast.
This means I may have to take the lamp apart completely, to get to the wiring, to make sure all wires match
the classic Rapid Start wiring diagram. I'm not too happy about that.

If and when you take it apart can you post pictures of the sockets and related wiring, also I don't know about yours but the screws on mine look like they can also be taken out with a standard slot head (AKA flat-head) screw driver

Mine can take a Philips screw driver, and also another screw driver with a head in the shape of a square...? But the ones
required to take the bottom panel off to get to the ballast, can only be used with a screw driver with the square shape.
Otherwise, I would've already done some work to the lamp.
But yeah... the type A ballast sucks. It gives me that compact fluorescent vibe... in the case in which if it does see
an EOL lamp, it'll fry/explode one of the capacitors or the ballast.
Might even do that at random during start up.

My curiosity completely got the best of me, so I didn't end up needing the square tipped screwdrivers. I used my pliers to get
the screws out, and I ripped that piece of crap ballast out of there. I then took the Advance Centium Rapid Start electronic ballast
out of one of my kitchen fixtures,and re arranged some of the wiring in that desk lamp to make it Rapid Start friendly... but now I'm
in a dilemma. I got the starting side of the ballast to light one lamp, but then when I installed the other lamp, that other lamp
starts up instead. It's so weird how I'm confused on how to wire this, when it should be so simple to me.
In short, I might need help in terms of a rapid start wiring diagram for the position these lamps are in, with the previous
wiring they have. (Yellow, red, red, yellow... yellow, blue, blue, yellow.)

That would be (Red, red, yellow/jumper, yellow/jumper... other end of one jumper, other end of other jumper, blue, blue.)

@Fluorescent05... ehh... man... brain freeze without the ice cream. My brain stopped.
What I might need is photos of how it should look with this PL lamp set up. That'd probably be the best bet for me unfortunately. lol

I have a 2 lamp magnetic RS 18 watt version (the one you linked me to) wired up. Would a picture of the wiring diagram be sufficient?

I gave in and took off the reflector portion of the lamp, I then got to the wires/sockets, took apart the sockets to make the
wiring corrections, put the sockets back together, installed the lamps and everything lit up as it should. I guess it was the wiring
colors that threw me off until I made the correct rearrangements. I'm putting the lamp back together as we speak, and I'm about to
fire it up. Should light up just fine unless there's a disconnection somehow lol

Are you still using the type A ballast? Did you rewire it to a rapid start wiring diagram?

@Fluorescent05, Am I using that Type A ballast?... NOPE. I'm no longer using it, but I am gonna keep it, mainly to take a photo of it.
I got that ballast out of there.
I corrected the wiring diagram and I'm temporarily using the F40T12 Advance Centium electronic Rapid Start ballast I have. I installed
that ballast into the desk lamp... corrected the wiring in the desk lamp and it fired right up with the Advance ballast.
I'm mainly using the Advance ballast as a test ballast, so that once I'm ready to install a magnetic ballast into this desk lamp,
the wiring is already prepared for me to do so.

The only one I found is this one. It is not on eBay and is extremely overpriced, though.

Update: just purchased another Sadelite lamp, and the ballast with this new one is *almost* exactly like the one in this pic. However... there
are noticeable differences. Also, the manufacturers wired the ballast differently compared to what I'm use to seeing with Rapid Start ballast
wiring... not sure if I could simply uninstall the electronic Robertson ballast and replace it with magnetic, without having to change
up the wiring again. Anyways, see here for the picture of the ballast: https://www.lighting-gallery.net/gallery/displayimage.php?pos=-159906
Added to that, here are two videos:
Start up of both Sadelite desk lamps, with one of the converted to magnetic: https://www.youtube.com/watch?v=zFcgI-m4wb0
Start up of newest Sadelite desk lamp, with one lamp successfully starting without other lamp: https://www.youtube.com/watch?v=y8Gnd8USFic
