Phoenix bulbs - SE vs DE

[Myka]

Thanks for all the input everyone! I know the SEs are difficult to get a hold of, but I do have a US mailing address if needed. Once a year replacement really isn't a big deal. However, if I put the effort into doing that, I would be HIGHLY disappointed if they weren't very similar to the Phoenix DEs.

I'm going to be using electronic ballasts, and if I use DEs I would have to retrofit my SE pendants, which is one of the reasons why I want to use SE bulbs. I'm using a DE fixture right now, but I am all out of DE bulbs with the current bulbs needing replacement. Time to put the pendants to use...and I would rather not have to retrofit them to accept DE bulbs. PAR isn't a huge concern, but I'm also not into wasting electricity on an inefficient setup. My current setup is inefficient for a number of reasons, and the corals are getting plenty enough PAR, but more for "free" is almost always better.
