Interesting results. Any plans to add VHO's to the set of tests?

Look forward to more tests Steve.

FWIW, Hamilton German 10K bulbs, were identical to my Ushio bulbs. Jayson had the mon sale for around $110 recently, and at times, {I bought four}, @$100

Also, Adam mentioned he just got an Ushio 10k from J&L for $102.

Hello Steve,

Maybe if you can do this for a few months measuring all sorts of data, we can put it in the library.

Interesting things to know are:
1) lighting intensity both under and above water line (ie 1" & 10" below water vs 1" above water, when bulbs are say 5" above water)
2) intensity changes over a period of 12 months
3) ambient temperature of bulbs, with room temperature as reference (maybe interesting to know how this changes over time)

If you can do that each month, we can update the write up monthly. Obviously, Steve only needs to e-mail me the new data every month and I can compile the table and graphics accordingly.

<font size="2" face="Verdana, Helvetica, sans-serif">#2 is easy, and it isn't to hard to raise my lights once a month to measure for #1, but how do you sugest I do #3? room temp (cabnet temp) is easy as I have a indoor out door thermomiter to tell me my cabnet temp and my water temp but I don't have a way to measure the temp of the bulb...
