LIGHTS

[juan rahmat]

Is it ok to use philips energy saving lights(white light)on a Reef Tank?I'm using 3x18 watts=300 watts.Per light is around 6500K.

you're gonna get a crap load of diatoms in a matter of time if you do that.

3 x 18 = 54

18W of FL light = 100W of Incandescent light

150W of MH light = 1500W of Incandescent light

I'm wondering i need to go back to school to brush up my math cos puzzling over 3 x 18 = 300?

the energy saving bulbs. use only 18 watts. but claim to produce 100 watts etc. theres a lot more to diatoms than just light.. whats wrong with 6500k a lot of ppl use that .

Those energy saver bulbs are FL bulbs. Nothing special about them. The so called '100W' claim is comparing light intensity with an incandescent bulb but because of the design, I won't be surprised that it produces less light than a 18W FL tube.

When manufacturers refer to the wattage of the lamp, they are talking about the power consumption and not the light output. Although light output is usually proportional to energy consumption, it is only comparable within the same class of lamps.
