Well, okay, if you insist ;)
Here is a before shot:
The original is an 18" T8 8000K fluorescent tube. The new and improved is a single 5665K LED. You can clearly see the change in color spectrum between the two. Brightness wise, they look fairly similar although there are more shadows with the LED since it is a single point source. My plan was originally to put three of these up, but maybe only 2 will be sufficient to get my 'moderate' light goal. I don't want to deal with CO2 so I can't go too bright.
Here is a picture of the LED itself, the yellow center is about the size of a dime, that is what contains the LED array.
As you can see, I've had a bit of trouble with screw heads snapping off ;) I haven't been able to locate any #4 self threading screws, so I attempted to use regular #4 sheet metal screws with ... less than ideal results. Oh well, it's a prototype and you are only suppose to use two screws anyways ;)
This is a picture of the LED driver. As you can see there isn't much to it, just a couple transistors (with one having a heatsink), a couple resistors, and a zener diode.
The final product will be mounted to a piece of 1/4" thick plastic and the circuit will be soldered to a prototype PCB. I'm not going to special order a custom PCB as that has a minimum cost over $100 which just isn't worth it for such a simple circuit.
