Purchased a 40watt Bulb and a 40 watt transformer along with some plants. The plants arrived very quickly. The other 2 arrived within a week. Everythings working great and my koi pong is nice and clear now. My only concern is the bulb, but I don't know if it's anything to be concerned about. I had to wait until night time to really see it but the actual fillament in the bulb is glowing bright orange on the corner and it just looks like at some point it's going to overheat that section and the bulb will be dead after that. I was wondering if that is normal for these bulbs and nothing to be concerned with or if it is possible something on my end. I have the right transformer and the correct bulb so it shouldn't be an issue of overload. Hopefully I can get some feedback. So far so good though! If you purchase plants. PLANT THEM THE DAY YOU GET THEM.
