Solar Mini Bulb replacement

Long time reader and first time poster.

First off, great great site!! I've really enjoyed a lot of the articles, especially those on fertilization. The comments in many of the posts here are very valuable. Such a great resource for the hobby.

I have some questions about replacing the ada mini solar light bulb. In the past I have purchased replacement bulbs through adg shop or adana shop online but I am wondering if anybody out there could recommend a bulb that I could pick up locally that they've had good results with? And if not locally, then maybe a bulb online that they prefer over the one that ada supplies with their setup? Also, how long do people who run similar setups go before replacing their bulbs? I am sure I'm a due.

I am currently running the PANASONIA/NATIONAL 27W TWIN FLUORESCENT LAMP on my mini m.

Thanks in advance!!

best,
