I currently have two 175 watt 14k MHs & two 46.5 T5s on my 125g. I need to replace the bulbs on the MHs. I like the 14k color but would like to know what brand lamp & color everyone would recommend and why?
I've been using XM 20K 250W bulbs. Sanjay likes the Ushio 14K bulbs for 250W applications. That's what I'm switching to next replacement cycle. You can take a look at his data at...
I can't do the Ushio, I don't have a pulse start on my ballast. I think 175 watt lamps are a little light for my tank but that is all I can do right now. So I wanted to get the best bulb possible for my tank.
