I simply ziptied a moonlight strip to my Sunpod. But, as I recall, the teklight's case is shaped at angles that are awkward for mounting moonlights. Like this, right?

If so, and if the tank is against a wall, you could wall mount a couple of spot moonlights or a strip and angle them down on your tank, as represented by the circles below the teklight here (ignore the dashes, they're only included as placeholderss):

Alternatively, you could find some of those swing arm spotlights, I believe that Coralife made them, and mount them on top of the teklight and swing them around and down behind the tek.
Good luck.
