Thanks mate!
I do like more specific details about;
- Lumens -
You can find it on the twinstar's facebook. However it only tells you the "quantity" of light. More lumens are not necessary better, in fact, more than needed will promote algae.
- Par value -
It depends on many factors, including height. On the other hand it measures between 400 to 700nm, and many wavelenthgs does not matter for plant growth.
- How many LED's in the fixture -
LED specifications are already available at Twinstar's facebook.
- Instead of what brand of led i wonder what kind they are for example; 5630 LED's -
5630 only tells you the size of the led and nothing more.
- Watt per LED -
They have different LEDs, so different w/led.
- What is the Kelvin value -
Light has 7050K
I don't like it when manufacturers decide what the customer should or should not worry about! ADA's does this as well with there new RGB Solar, they say; " Why do you want to dim it, the color rendition is perfect. "
In my opinion a piece of hardware should do what ever the customer wants it to do. Two most important things are;
- When battling against algae it is in some cases important you can dim the light for the plants to take over and get things balanced again. -
Yes you are right, however please remember we cannot measure many wavelenghts with our eyes. Anyway you can just turn them off like T5.
- A LED fixture should always be dimmable to give the customer full control so there can be sunset's sunrises and maybe moonlight. -
Functions can be cool, but just for the users. However they are not important for plants and fish. Instead of it, in my humble opinion, I think the most important is the quality vs design vs price. What would you prefer? Quality and performance or functions? Pro Aquascapers only need perfect light for their projects, functions are optional.
I find it strange that company's manufacturing fixtures don't understand this. Where i live Customer = King. In the smartphone market it isn't any different though
Everything has a reason, but please remember, in terms of light performance don't focus in what your eyes can see 😉
(for a cheap copy of good value; Chihiros seem to understand this!)
