Iwaski 150w DE 50k

[ice cream jones]

These bulbs are on clearance for $30, amazing price! But are they a good quality bulb? My current is a 14k, and it over 2 years old. I'm guessing its most likely the cause of my sudden rise of diatoms :angryfire:

Eye Lighting (main company of Iwasaki) makes the most high quality aquarium HID lamp ever built, even more so than Ushio. We have sold Iwasaki lamps since 1996, and I bet we have returned less than 10 of them over that many years.
