AH Supply 2x55 Kit Uses

What can you use an AH Supply 2 x 55 watt bright light kit for? My PAR data, using GE9325K bulbs, about a year old, and with some analysis, suggests that this light can be used on a wide variety of tanks from 15 gallon to 90 gallon. The light intensity at the substrate depends on the distance from the light to the substrate, and the uniformity of the light over the substrate depends on how high above the tank you suspend the light, and whether the bulbs are end to end or side by side.

Here are some tank sizes this will work for: (This is intended only as a general way to determine if the 2 x 55 watt kit can be used on specific tank sizes. The actual PAR intensities for the bulbs you use can only be determined by measuring with a PAR meter.)

You could be right. I suspect that the 36 watt kit provides the same intensity as the 55 watt kit, but over the shorter length of the bulb. And, 100 micromols is really too much light as I see it, but some people want that much and more. Also, notice that I listed those tank sizes for one bulb only.

 

No, I only posted that because it occurred to me that I have enough data to predict with some confidence how it would work with a variety of tank sizes. I hope this will encourage others to get some good PAR readings with T5, T8 and MH/HQI lights so something similar can be done for those lighting types.
