I am using 1x15W and 2x15W currently in my 2FT. And tied Riccia on a rock at the bottom placed on a particular bright spot. No CO2.

1 of the Tube half-blocked by the single lower 15W hood. No choice as no space maybe change to UGF to free another slot when I am back from Taiwan.

So considering 37.5W ... hopefully enough for it to survive and grow slowly


Any Comments ?

The measure of brightness is actually lumens or lux. The ads that says 20W = 100W is the compared FL/PLs to Incnadescent (as explained by Vincent). Which means to get 20W worth of brightness by fluorescent you will need 100W worth of power for incendescent.... understand?

I must remind you guys again that the 3W/g is juz a guide. Fluorescent tubes brightness only differs slightly in terms of brightness. So to answer your question, 36W means power consumed.... brightness is a different story.

so sherwin.... still stick to what's writen on the tube or box 20watt even if it has the brightness of 100watt......... [:]

Deck,

Yeah.... the guide is based on fluorescent wattage.

UGF is not suitable for planted tank (rooted plants). For Riccia, they need lotsa CO2 and lights. Might want to rethink abt CO2, maybe DIY CO2?
