According to Sanjay's tests the Helios bulb is the best 400 watt 20000k mogul bulb on the IceCap electronic ballast, but finding them is tough. Only found two online stores that carry them, and both are out of stock. According to them new shipments from their supplier are at least a month away from being sent. That delay got me to wondering if there has been a problem with them. In one of the posts I found, it said they were prone to early failure. It got me to wondering if that's why so few dealers carry the bulbs. Is anyone using this particular 400 watt 20000k bulb, and if so what's been your experience?
Anyone with IceCap electronic ballasts found a better 400 watt 20000k bulb for tanks 30 inches deep?
