I just saw those posted on ebay... I don't know who's selling them... at that price..but they're giving them away.... it's one thing to sell lots of 10, but it's another to charge less than the cost of one .. for all 10. when I see pricing like that, I often become suspicious as to where they got them that they are selling them that cheap.
As for the Hadco BL5016... I agree with the consensus... I've been using these fixtures since they came out... decent, solid.. basic fixture with a pretty durable finish...
The value when you buy with lamp and stake is good... I also know that they have or will be coming out very soon with the combo of fixture, stake and Phillips LED.
