LED Panel

[sherman]

Hi bro Chua,

You mean the whole LED light set or the LED time controller?

[sherman]

Oop I mean bro boyington

[boyington]

Maybe can break down the cost of the LED part & the LED time controller part, would like to know the cost versus buying ready LED sets. Thanks.

Seoul 3.5W Star LED (P4 Version)
Z-LED P4 series, similar to LUXEON Star LEDs

SEOUL Star LEDs are alsmost similar to the LUXEON Star LEDs and belong to the worlds brightest high power LEDs and most popular solutions for evey application based on semiconductor illuminants, too. The new P4 series is the new semiconductor STAR and a hard competitor to Luxeons K2. Depending on the forward current the P4 can get more than twice as bright as the K2 can. The Lumen/Watt ratio is currently unbeatable.

Please note

You should fortified take care of the different selections (bin codes) od the LEDs. For example: White LEDs of Rank "U" have a luminous flux of about 91 till 118.5lm and lower ranks a lot less (@ 1000mA). These differences and the later light efficiency of your application can thereby highly fluctuate. The low forward voltages (Vf) assure a low development of heat that benefits a maximum live time of the products.

Thanks bro, appreciate your time and effort for the info.

The cost of DIY led light is actually the same or sometime even more expensive then you buy off shelve.

But of course the design and material u get is what u choose and usually u choose the best.

Long time since I update this thread.

The 2 set of LEDs I build in 2009 I am still using in my present 5 footer setup

Over the years many new concepts and products will introduce in the aquarium

led light set.

The led light set I build in Jul 2009 although is still coloring and growing sps 

in my tank but at a lower efficiency.

Its time to build a new set of led aquarium light for my present 5 footer

[sherman]

Just a quick recall.

This is the first proper led light set I build in 2009

44 leds on star

Today most aquarium led light set for reef aquarium come as full spectrum.
This is suppose to improve the original white/ blue light design from 2006.

But what is full spectrum? Does it really improve the growth and color of
your sps and other livestocks ?

So before you start throwing your money for a full spectrum led light set
make sure you get what you are paying for.
Make sure you are paying for the best of your livestock and your eyes

Below is a writeup by Dmitry Karpenko, Vahe Ganapetyan .
They do a in depth study what is the actual light marine
organism is getting in their natural environment.

Feature Article: Light in the Reef Aquaria
By Dmitry Karpenko, Vahe Ganapetyan
Light is one of the main life-supporting resources on our planet. Being photosynthetic, many marine invertebrates require light to live. Their symbiotic zooxanthellae need light for photosynthesis to produce sufficient nourishment both for their own use and for the host coral.

Perhaps every reef hobbyist is willing to provide the "right" light to his corals - both correct spectrum and sufficient intensity are important. Before we consider how to implement this "right light," we shall first try to understand what kind of light marine organisms get in their natural environment.

[sherman]

Different coral species live on various depths: some live in very shallow waters, whereas deep water corals, such as Bathypates spp., can be found on the depths of up to 8000 meters (about 5 miles). About 20% of all coral species are non photosynthetic; they do not require any light as a food source. Most corals, however, are photosynthetic, and these are the species which are kept most often at home aquaria. We shall try to figure out what kind of light they prefer.

[sherman]

Below is the graph of solar light penetration into marine water, depending on wavelength, compiled by the Institute for Environment and Sustainability of the European Commission [4] (Fig. 2):

 

[sherman]

The horizontal axis is the light wavelength, in nanometers(nm) , and the vertical axis is depth, in meters, at which the intensity of that wavelength is equal to one percent of the intensity at the surface. It is clear from this graph that wavelengths between approximately 370 and 500nm best penetrate into the depth. In other words, violet and blue parts of the spectrum penetrate best into seawater, whereas green light is much worse at that, yellow-orange is even worse, and red light with wavelengths longer than 600nm is only capable of penetrating very shallow waters.

 

This data is very important in designing or providing the light to your reef aquarium

[sherman]

Fig. 3 show us light's relative spectral distribution at the surface and at the depths of 5m (about 16.4 feet) and 15m (49 feet). Note: 15m is the maximum depth at which we can still find many light-demanding corals in nature. At the depths below 20m, the number of light demanding species sharply decreases.

 

[sherman]

The light-blue graph corresponds to irradiation on the surface, the blue graph - to 5m depth, and the dark-blue - to 15m depth. Note that with depth, the red part of the spectrum virtually disappears

[sherman]

That is all for today. Tmrl we continue to on light adsorption by zooxanthellae.

[sherman]

During hundreds of millions years of evolution marine photosynthetic organisms adapted to best utilize mainly the violet and blue parts of the spectrum, which is more abundant in their environment, and are not very sensitive to the red spectrum
