Questions on Lighting

Hi, all!
I have a few questions concerning lighting for a 26-gallon bow-front aquarium thatís 24 inches deep.
Iíve been using 18-inch fluorescent bulbs made for aquariums, but theyíve been quite a hassle. So far, Iíve had three or four burn out on me (old age for two of them, but the others more tricky to explain). Theyíre hard to get in and out of the hood, and they get hot too. I even had one explode right over my tank! Eeeek, MERCURY!!! (Donít ask me why or how it happened. I have no idea. And yes, it was probably my fault and not the bulbís.)
But still, Iím tired of fluorescents. And the LEDs over my ten-gallon are blissfully low-maintenance. Theyíve lasted for years! And they provide a nice build-up of algae for my snails.
So now what Iím looking at doing is buying a white-red-blue-green LED light structure, but figuring out just how much of it my aquarium needs has me confused. Do I measure by watts or lumens or something else? How many of them?

My aquarium is low-tech, but I donít mind having a little too much light to encourage algae growth. I also want to grow lots of low-tech plants and maybe aquaponic-style plants too. So does anybody have a comprehensive calculator or formula to figure out how much light I need? If it will help, I can name the light Iím trying to consider right now...

-Ah, itís: ďPawfly LED Aquarium Light Adjustable Brightness Fish Tank Plant Lighting with Extendable Brackets, 18 to 24 InchĒ.
I found it on Amazon for what looks like a very desirable price. Iím not sure if it has a timer or not, but I donít really care. I just turn the light on when I wake up and off an hour or two before bed.

(Oh, and the reason Iím wanting to get a new light is because my current fluorescent recently burned out. I figure it might be worth it to pay two or even three times the cost of my fluorescents to make sure I never have to replace the light again.)

Any suggestions welcome!
Thanks in advance!

I measured again, and my aquarium is actually 19 inches deep, not 24
