Comparison of two similar yet different fixtures made by Mesko. On the left there is a first gen OURW2250 fixture for two 250W MV lamps. On the right there is a single lamp first gen OURW250. In OURW2250 both lamps are in a vertical position, in OURW250 the lamp is positioned at a slight angle close to horizontal position. Both first gen fixtures have separate lamp chamber and separate gear chamber connected together by screws.

Yes, they are quite sturdy. They have good rubber gaskets connecting glass bowl with lamp chamber which if properly maintained don't allow bugs and other junk inside the bowl (though in some where there was some tampering did catch bugs). Screws connecting the chambers are good as well, only in some in extremely bad shape I've seen the lamp chamber hanging from gear chamber on a power cable or lacking the lamp chamber altogether as it did fall off some time ago. As for particular problems it is important to mention that some types of glass bowls (there were many during production) have inadequate optics. When used with coated lamps it isn't that problematic but when retrofitted with tubular HPS then the problem becomes very pronounced:

Also last produced variants of single lamp version were given plastic bowls instead of glass and while initially those new bowls distributed light evenly, soon they've became yellow and milky due to degradation from UV.
Overall quite good fixtures but not perfect.
