Γνωριζει κανεις ποια ειναι η αναλογια watt leds σε watt T5?

Με εναν προχειρο υπολογισμο που εκανα απο εδω

http://www.americanaquariumproducts.com/Aq...m_Lighting.html

νομιζω 8,5w ειναι αρκετα για 100lt ενυδρειο.

Καθως εψαχνα παρατηρησα οτι led με led εχει διαφορα. Αλλαζουν τα luminem, η γωνια φωτισμου και τα watt. Τι τεχνικα χαρακτηριστικα εχουν τα δικα σου led?

Εδω ειναι τα τελευταια νεα που ειχα απο τον τυπο:

Hi Miliotis,

Here is our single color waterproof led strip datasheet:

http://ledz.com/led.strip/STRF3X-WP.pdf

Smallest piece consists of 60 LEDs 40" (101.6 cm), for

150cm and 80cm or other length, sorry we do not manufacture.

And our strip is connect with power supply , not battery. Usually

one power supply connect with 2 meters strip.

Our STRF3X-WP types of strip is just our suggestion. We have

no experience in designing lighting systems, we can tell you only

characteristics of our LEDs (lumen output, angle, lighting pattern,

voltage, current).how to use it is up to customer.Pls confirm.

Have a nice day

Ella

16$ το μετρο, καπου 11Ε.
