I love the hagen GLO lighting, but I have been reluctant to get them because Hagen is discontinuing them. they are on sale at all the LFS's in my area as a result. you can get them at half price right now..
just a heads up. I would imagine they are coming out with something to replace them with, because their bulbs do not fit in other T-5 strips because they make their bulbs an inch shorter than everyone else.
eg. a 48" strip normally takes a 48" bulb.
the hagen glo takes their own 47" or 46" (I can't remember which) only...they were sneaky...
