For dem som fulgte med her, evt titter innom nå. Jeg sendte melding til eheim, for å høre. Fikk et ganske utfyldene svar =)
Dear Mr. Berg,
thanks, for the nice picture of your aquarium layout.
Eheim always try to use the best and most efficiency techniques for their products.
Please note, that the consumption / power-input (watt) says nothing about the light-output (lumen, short-term “lm”).
If you want to compare lighting-system, please look at the “lamp efficacy” (lm/W) at 35 °C.
That’s the reason why we are glad, that we need only 39W power input for similar light-output as competitors which need 45W input.
Only some short information about used lamp & ballast:
Class of energy efficiency: A (best class for light tubes)
Correlated colour temperature CCT: 6.500k
Lumen after 100 hrs operation time 3.400 lm (at 35°C)
Lamp efficacy at 35 °C 87,2 lm/W
EEI ballast energy class A2BAT (best energy class)
Electronic Ballast efficiency >99%
If you think you need more light (caused by light intensive plants), best way is to upgrade with additional incpiria Power-Kit
The additional lighting system consists of: light unit, light tubes and reflectors
The pricing is really fair, (compared to competitors which have no reflectors includes & sometimes no light-tubes)
watt per litre:
Please do not use such formulas, cause the most information about plants (watt per litre) which you will find at books or internet,
are from Mr. Paffrath.
The problem is, that this information are from year 1979.
At 1978 the T8 lights were not so efficient like today (about 10-20% less), the magnetic ballast had only efficiency rates around 50%
and the T5 Technology (up to 30-40% better than T8) was not developed yet.
Some Paffrath sheet (sorry only in german):
