I have. I liked them. Not as nice as the Phoenix but still nice. I rate the 14K (duel ended) as such..

1. Phoenix 14K (Good balance between growth and colour).

2. XM 15K (A good alternative to Phoenix).

3. Ushio 14K (much whiter than most which means great growth. Needs to be supplimented with a lot of blue T5s though).

3. Giessman/Hamilton/etc (kinda meh on these ones. They get the job done).

4. eBay 14/15K ( cheap, but don't tend to last long. Either burn out quickly or colour shift noticeably earlier).
