HI,
We always get conflicting info about these bulbs. They told us a few months a while back, something to do with a big fish convention in germany or something. Then they told me they would be able to fill our backorders in a few weeks, that was about 10 days ago. So far as we know we are on track for a couple weeks, but they could change there story again.
If we hear something different i'll post it on the board. We do not want to mislead anyone, we are just relaying what we are told.
If you can't wait, i think the AB20k is a really close looking bulb to the AC brand. I've tried every 250watt DE on my tank and the 20K AB and 14K AC i thought looked really close. I didn't get to break the AC in though, only ran it a few hours. I'm not a huge heavy blue fan though, so i've switched to the 14K hamilton DE which is more white then blue.
thanks
