ESD light bulbs in Ilford multigrade 500H

[gorbas]

Hi Guys, Just curious, does anybody here is using ESD bulbs 150W/120V instead of "regular" ELH 300W/120V bulbs. Looks like ESDs are not affordable and easily find as ELHs?
What brand are you using and is there any issues with their life span?
Yes, there are bunch of them from $20 and up, so investment for 6 bulbs (2 in the head and 4 spare)+shipping is small fortune. Maybe I'm better off with just sticking ND 0.3 or 0.6 in the mixing box.

Nothing like the correct bulb, I say.

I note that the manual for the 500H indicates that the first 5 programs of the 10 available provide 10% stepped increases in the green light component, based on using a ESD bulb. So that might factor into your thinking.

Tom1956, both bulbs are correct. It's user preference: 2x150W or 2x300W.
Matt, thank you! I do have the manual.
I just do not like to print with f16 or f22 and short exposure times.

Well, post # 3 convinced me to take off my colorhead on my 67C and re-install the regular black-and-white one and just using my filters. When I put on the color head to escape the filters and just use CC conversions, I knew of the short life, expensive, temperature-changing projection-style bulbs. This thread re-affirms that.
