the spiral bulb loses a good dela due to restrike. The bulb should not be pointing top down, it should be sideways mounted.

Your package should have the lumen output of the bulb. If it says 700 to 850 lumens, that would be equivalent to one 15w T8 bulb.
If you have no reflector, divide that in 1/2.

Now, the intensity of the light is still 19w... I find that low light and moderate light plants grow well, high light plants just won't, even with DIY CO2.
2 23w spirals on a 10g wouldn't grow myrophylum tuberculatum even though 90w on the 60g does. 1 C.F. 36w bulb keeps it alive but it won't thrive... confused yet? Smile

That depends on the mini compact fluorescent you are using. If it's like http://www.bigalsonline.com/catalog/product.xml?product_id=23441;category_id=1845;pcid1=1843;pcid2= or the coralife type, I don't think you're losing much. Having decent reflectors above them wouldn't hurt though, as most incandescent (screw-in) light fixtures are lacking in that department.

In my opinion you are gettin gthe equiv. of 2 15w flourescent tubes. You lack the intensity of the 30w bulbs.
