When you can get LED's that point in the right direction to begin with, these don't make much sense. This is a replacement for an incandescent light bulb, so it's designed to throw light in all directions. Thus, most of your light, your going to have to try to reflect back to the tank, during which process a good % will be lost. 450 lumens isn't much to begin with.

They do make mogul based LED "spot lights" where all the led's are facing the right direction. they don't have tremendous wattage, but it should be a much lower number of diodes(than the corn cob) which typically means you will get greater depth penetration.

Now that would be much more useful. The number of bulbs is less important than the wattage and the lumen output.

There is a 5X3W E27 in the "spot light" config that is advertised to yield 900 lumens. Not too shabby. There are also of 3x3W that get you around 500 lumens. The 9W bulb should be around $10 to your door.

Oh nice these corn cob led can be used in a regular fixture? What's the kelvin/color temperature rating on these?

I don't know what light fixture you have, could be the "US Standard" Which a quick google search appears to be E26, or "medium base" in USA. OOPs the E27 appears to be the EU medium size. IF yours says E17, then you need "US-Intermediate" or just look for E17.
