There are also LED lamps for aquarium: now the teconologia of high efficiency LEDs entered by force in any area ... and with remarkable results even in the aquarium! The LEDs consume little, have a wide range of color temperatures (in the aquarium is important) and they last a long time, at least twice a neon tube "normal".

I've met a couple of the best stocked shops in aquariums, aquariums with centalina and complete LED lighting, and the cost was not prohibitive, very close to the cost of a T5 system of medium quality.
Instead, the ELOS has a beautiful ceiling in the list with 18 LEDs, the ELOS E-LITE with ONLY 64 WATT consumption and emission of light comparable to a 150 watt metal halide lamp!
The color temperature is 10,000 ° Kelvin. He presented Interzoo Nuremberg this year and I must say that is very pleasing to the eye, small but not too flashy nor invisible ... absolutely proportionate to the System Mini for example, with the tank almost cube 43x43x40 (h) cm, short makes his light and his beautiful picture above the aquarium. :-)
The price is about 550 €, not low even compared to innovation in design and technology, let us say at once, in line with the Elos products in general, following a business strategy similar to that of the ADA, ranking among the voluntarily products "luxury" in view of the aquarium. The Mini System whole, complete system for a mini reef and through, is 1200 price list.

I've also read conflicting info on how to address pollution ... why always the most common rationale is that if something consumes less then it is more eco-logical, greener, more green. Is not so simple ... you have to see the entire product as it is built, with such technical and expenditures of energy, then where else will need to be replaced in the future, creating pollution "e".
