Good luck.
In the aquarium world, 70 and 150 (DE), 175 (SE), 250 and 400 (SE/DE), and 1000 (SE) are the common sizes.
Those intermediate sizes especailly in the lower range just aren't made.
My new 175W came from fcbz-1111 and wow what a difference way way way way brighter and much whiter, which I like). I dont think ill need to worry about much of anything

Oh yah. Plus if the ballast is probe start a 70W (which is only available in HQI for aquariums) won't ignite.
