Click to view full size image

SES (a brand I've never heard of) electronic instant-start ballast for 4 F32 lamps.
Hasn't yet been tested to see what happens with an EOL lamp, or it it'll overdrive.

728V OCV and 50F minimum starting temperature? No way that's right. Also, the wiring diagram is different from most other 4x32 IS ballasts. I've never seen this model, but the SES 2x40/34 RS ballast is one of the worst ballasts I've seen.

I like my lamps thick, my ballasts heavy, and my fixtures tough.

How do ballast makers get away with such a high OCV? Because as far as I know most of the sockets and the wiring is only rated to 600V
Unless it only a starting pulse of that voltage (Much like Pulse-Start Metal Halide and HPS)

As soon as the lamps strike, the voltage drops significantly. With instant start, this only takes a small fraction of a second.

I like rapid start because it works the complete opposite way of instant start.

@nicksfans: Never seen one, is the SES 2x40/34 RS ballast junk because it doesn't last long? or because it does a poor job running lamps?
I have a feeling it'd start well below 50F if we get another night where its below zero (F) I think this thing is gonna have to go outside for a 'cold test'


@LampLover:
Not positive on this, but I believe specs for a F32T8 are: 32w/265ma/121v
So once running the ballast will be putting that (or less) out to the lamps.

@TheUniversalDave1:
I've always loved rapid-start...probably in part because that's how most lights started up when I was young
Instant start is boring, but certainly works better in cold weather LOL

------
edit: overdriving test has been done & it works.
Some other time I'll have to finish off an EOL lamp with it

Colored Fluorescent's such as F40T12 Red or  Green or Blue are awesome...

It's not that the 2x40/34 ballasts don't last long, it's that they are pathetic at running lamps. There is a lot of variation in how hard they drive the lamps, but all of them underdrive the lamps horribly. That's not the worst part, though. Some of them don't provide enough cathode heating voltage, so they eat lamps like you wouldn't believe. I've seen them kill lamps in a matter of months, and not even with frequent starts.

I know this doesn't drive F32's at a full 32w (that'd be atleast 1.07a, where the label says it only draws .9a) but atleast it doesn't seem overly dim or anything.
Sounds like the 2xF40 is pretty crappy, the least they coulda done is have it give proper cathode heating voltage.

edit:
After testing: Line current on this is .81a, and wattage is 97w, so even if ballast-loss was zero that'd be 24w/lamp.

Colored Fluorescent's such as F40T12 Red or  Green or Blue are awesome...
