We're running their 2,000, 4,000 and 7,000 watt lamps... all with excellent performance.
I wouldn't want the 7k bulb dropped on me. It IS a tank!
Oh... this will probably offend some sensibilities here, but... I ran one of their 7K bulbs at the drive-in for a season at full power... put about 700 hours on it... then I brought it to the indoor & ran it at 4,000 watts to see how far it would go before it got dark or instable or ???
I got the bulb up to 4,000 hours before it started to wander... something I've lately looked for at more like 1,200 to 1,500 hours. It still looked good physically... very little darkening. The anode looked "scuffed", not as pitted as I was seeing on the Perkin Elmers I was getting.
Don't know if that's repeatable... it's certainly not recommended by anyone... but not bad performance for the buck, and maybe an indication of conservative design?
