I don't think they're the same. From the link you provided ... "Different manufacturers call ceramic metal halide lamps by different names: GE Lighting – CMH, Osram – HCI, Philips CDM and Sylvania – CMI."

The CMH we've been talking up here is Phillips. What Phillips calls CDM are "high-pressure Ceramic gas Discharge Metal-halide lamps.*" I won't say it's a bad lamp (no idea) but it's not what Phillips would call a CMH.

If you cannot get them then get the 400 eye blue as it's an awesome bulb as well. But you will need a MH ballast. Personally, I like the eye blue much better than the cmh in veg, and I now supplement with the cmh in flower. In other words, I now flower with a 400hps and a 250 cmh as I did not like the outcome of growing all the way through with only cmh bulbs. That's my opinion and I’m sticking to it. 
