Just built a new exposure unit and 4 bulbs in a row are way different looking through a camera lense. They are on different ballasts then the other ones which is probably why they look different...should I be concerned of the light pattern? Image below...

I wouldn't have a clue, but that looks pretty wild.

Wild guess and I don't know how electricity works to well, I'm no juggalo, but is there a lack of power being supplied that's making it fluctuate oddly?

What I mean is, if a series of lights strung together and power running through them, does it somehow at one point get weaker down the line? I'm not sure I know how electrical currents work.

The ballasts those 4 bulbs are connected to are for two 40W bulbs each. The bulbs are 20W so maybe thats why the light pattern is different? They (the ballasts) are also much older then the 3 news ones I have. I'm just curious if it's going to matter during exposure....but yeah it's fucking crazy looking.

Did you by any chance use tempered glass for the surface?

No. in the picture above there is no glass on the table

I did rewire just those bulbs and it does the same thing so I don't think it's a power supply thing. The other crazy thing is that those bands of light move very slowly across the tube. I'm going to do some step wedge tests after I get a piece of glass cut for the table. See what happens I guess...

Talked to an electrician about the crazy light waves. If anyone builds a table it's really important that ballasts and the light bulbs you are putting in the table match. So if you have 20W bulbs you want 20W ballasts. The reason I'm getting those crazy bands is because the lights are 20W but on 40W ballasts so they are getting way more juice then they need. It will burn the lights out quicker and it could even be a safety hazzard. Just and FYI...
