Comparison to other lighting technologies

See luminous efficacy for an efficiency chart comparing various technologies.
  • Incandescent lamps (light bulbs) generate light by passing electric current through a resistive filament, thereby heating the filament to a very high temperature so that it glows and emits visible light. A broad range of visible frequencies are naturally produced, yielding a "warm" yellow or white color quality. Incandescent light is highly inefficient, as about 98% of the energy input is emitted as heat.[15] A 100 W light bulb emits about 1,700 lumens, about 17 lumens/W. Incandescent lamps are relatively inexpensive to make. The typical lifespan of an AC incandescent lamp is around 1,000 hours.[16] They work well with dimmers. Most older light fixtures are designed for the size and shape of these traditional bulbs.
  • Fluorescent lamps (light bulbs) work by passing electricity through mercury vapor, which in turn emits ultraviolet light. The ultraviolet light is then absorbed by a phosphor coating inside the lamp, causing it to glow, or fluoresce. While the heat generated by a fluorescent lamp is much less than its incandescent counterpart, energy is still lost in generating the ultraviolet light and converting this light into visible light. If the lamp breaks, exposure to mercury can occur. Linear fluorescent lamps are typically five to six times the cost of equivalent incandescent lamps but have life spans around 10,000 and 20,000 hours. Lifetime varies from 1,200 hours to 20,000 hours for compact fluorescent lamps. Most fluorescent lamps are not compatible with dimmers. Those with "iron" ballasts flicker at 100 or 120 Hz, and are less efficient.[citation needed] The latest T8-sized triphosphate fluorescent lamps made by Osram, Philips, Crompton and others have a life expectancy greater than 50,000 hours, if coupled with a warm-start electronic ballast. The life expectancy depends on the number of on/off cycles, and is lower if the light is cycled often. The efficiency of these new lamps approaches 100 lumens/W.[citation needed] The efficiency of fluorescent tubes with modern electronic ballasts and compact fluorescents commonly ranges from 50 to 67 lumens/W. For comparison, general household LED bulbs available in 2011 emit 64 lumens/W,[17] with the best LED bulbs coming in at about 100 lumens/W.[18]

So is this that sufficient for low light level plants?
I've been researching this and people claim that it will work.

I'm calling in some extra help on this one - it's out of my league.

Yes, that light will be fine for the plants, however, bare in mind most cichlids will eat plants.

About the only the ones they will not destroy are Java fern, Anubias, anything else and will test them to see if they like them, if they do, they will be gone very quick.

what cichlids do you have?

Could I put Hornwort or Water Sprite in with the Cichlids?

I'm not big on Cichlids, the only ones ive kept are angelfish and Bolivian Rams. I know that larger Cichilids like to dig up plants so I would assume that hornword and Watersprite would be good for them since they float xD.

I've seen my fiancee's angelfish root up my plants when they were smaller but now that my Amazon Sword is alot bigger he doesnt mess with them, I do however see an unrooted plant every once in a while.

I usually find all my plants locally, but if i were to order online i would use liveaquaria.com just because its a link i followed from drsfosterandsmith.com and i trust that site.

Is there any supplements that I should buy for these three types of plants?
