Vad ca nu exista un topic pe aceasta tema, si prin cautarile pe internet am descoperit un articol foarte interesant despre cum se compara lampile cu LED-uri fata de luminile MH:

http://www.advancedaquarist.com/2012/3/aafeature

Cum deocamdata folosesc un bec simplu (Dennerle de 24W, 3 bare albe si 1 albastra http://dennerle.com/de-ga/Aquaristik-Aquariophilie-Aquarium-Acquaristica/Nano%20Marinus/GA_Nano_Marinus_Reef-Light_5619_1031.pdf ) sunt tare curios cum o sa mi se para acvariul cand voi trece pe LED-uri.

Conform articolului de mai sus: " ... there are significant spectral differences between the LED spectrum and those of the most popular MH lamps. The LEDs tend to have more output in the blue regions 400-500 nm range, while lacking in the warmer regions of the spectrum. This could explain why the aquariums tend to have a "flat" look when lit by LEDs. Lack of the red spectrum results in corals and fish with red color to look lack lustre. Lack of a broader spectrum and missing quantities of output at wavelengths to promote a more full spectrum is often a concern cited with LEDs, and it is obvious when comparing the spectrums to metal halides. As seen from the newer generation of LEDs there is an attempted to address this by providing more choice of colors (and channels of control) to allow tweaking of individual channels to enable users to fine tune the look of the aquariums and provide the ability to have one light fixture with the potential to satisfy a wide range of users."

Aqua Illumination contraataca pe piata ledurilor

http://reefbuilders.com/2013/05/17/ai-hydra-led-coming-hot-95-watts-399/

20 de canale dimmabile separat, practic fiecare led poate fi dimmat independent!
Si au inclus cam toate lungimile de unda pe care si le-ar dori un reefer

O zi buna,

Dragos,
Pune te rog link-urile cu explicatii si in sticky-ul cu link-uri de la Diverse.
Multumesc

Arata foarte bine, si la un pret mai acceptabil.
