I've just bought a 26w solar duo boy http://www.aquatic-nature.be/2eng_verlichting1.html . The lamp is an energy saving lamp and it says on the box that 26w is the equivilent to 100w standard light bulb. The lumen rating is 1505. So, for my 20 litre tank do i have 26 watts of light or 100 watts? Thanks
