I've ran Ushio 1000w DE HPS and they performed just as good as the Eye Hortilux Super DE HPS. I've ran Philips, Gavita, Ushio & Nanolux in no particular order. The Ushio, Gavita & Eye Hortilux are my go-to based on whatever is priced lowest. lol
Ushio is going to be a more economy option but they perform very well and last about 14 months before I notice any deminishment in PPFD or spectrum. Eye Hortilux DE HPS bulbs seem to start declining in performance as early as 10-12 months.
