Juwel Rekord 600 T8 Lightning
I am soon going to change the light after one year and do not know what should i get. Juwel lightning have Day-Lite and Warm-Lite both at 15W each. What should i get to maximize the plant growth? I know that the light is low but at least I try to give more.
Also it is right that after one year the light will deteriorate that is why we should change them at a yearly bases right?
get a better light and it will help keep the plants stay healthier for a longer time.plus they grow better and lusher with it
The Day-lite should be better, but do you have a kelvin rating for it? "Daylight" is usually around 6500K which is fine. "Warm" is less kelvin, more red and less blue, and might also work (depending upon the rating) but the colour rendition will be different. The "daylight" should bring out the natural colours on fish and plants.
T8 tubes last 3 years. The old T12 (the "fatter" tubes) had to be replaced every year, or so most suggested.
These bulbs are the Juwel make. They do not have any Kelvin rating for them. I will get the Day Lite then. Also in the website they suggest to be changed every year because the light will deteriorate and plants will not stay healthy any more. That is why i am asking here to see if this is true.
The website is out to sell their products, and unfortunately this has to be remembered when you are taking "advice" from manufacturers or retailers. I used to replace my T12's every year. I now have T8 tubes and since installing them in October 2008 and July 2009 I have not replaced them and I intend to go 3 years before I do.
Ok thank you
