So not the most scientific of observations but so far (one day) I'm happy with the new lamp. I ended up getting the 150 watt, 14,000K HQI. It's a little more blue than I would have liked but meh. I guess well see what happens after break-in. As of today my leather's are looking REALLY good, my clam is the most open I've ever seen it and my one mushroom is INCREDIBLY enlarged. All that said though, could just be a case of a new lamp... might have happend with ANY lamp. I really wish I had access to a Lux meter... Might have to do some asking around in my area.
