We switched to mostly Satco in our office and they’re pretty solid. For these bulbs they are marginally better constructed than most of this style that are in stores, but they still fail and heat is the culprit most of the time. In an open air fixture it’s not a concern even if it’s dusty. We’ve usually had the higher wattage models in standard CRI but did have two of the high-CRI - unfortunately those were both in frosted glass fixtures so I can’t really comment on rendering. Those two eventually both died after I think 3-/2 and 4 years or thereabouts. We’ve used a lot more of their PAR track bulbs and those are ok, not stellar, but the price is right and the shortcomings aren’t really noticed by anyone other than a little glare in some locations.
They do stand behind their warranty, though, which is great. There’s no guarantee you’ll receive the same product as a replacement, however, since they have recently changed things up a bit…with the newer models they seem a little cheaper and they also dropped the max temp rating for some. But I wouldn’t hesitate to recommend any of their products. (come to think of it, I’ve also used a couple of their halogen tube shop light bulbs which were well made and lasted their rated time, and we did their higher wattage CFL bulbs for awhile, too, which were great, but we used more from TCP just based on supplier availability at the time.)
