If you are afraid of burning a hole, buy a 20x24" sheet of Rosco full white or Lee 216 diffuser.

Thanks! I am very interested in this, would be perhaps better than an ND filter and easier to replace should the bulb burn a hole into the ND filter. It's a really hot bulb, I could cook an egg on my enlarger head!

Can you explain a bit more about it? It seems like a non traditional way so I can't find anything about it.

100 to 75 watts won't help you and it's not worth the trouble, absolutely.

5x7 should not be the reason. I still got 6-8 seconds with 5x7 paper on my color LPL (i think 75watts bulb...) with 50mm lens set to f/11 i think.

I am seriously puzzled by your 1-2s exposure times.
