Pasar Malam - Home Tanks

[clee123]

Awesome lah bro, planted and marine !!!

Fish and Bear's palm --- best of both world

Are you gonna put in your ace discuss fish in it ?

It will depend on how the tank come out to be... let's wait and see...

Sir Crispin, I'm convinced that I must drop by your place the moment I'm available this week.

Apologies for the delay as I have some urgent family matters to settle these few days. Saturday would be the opportune day to visit ya.

Of course, at a time convenient for ya.

bro,

You can drop by today evening or open house on Monday (public holiday)??...

After few days of Pasar Malam, here is how the 4 footer looks like:

I give it an Avatar look after all the major rock and corals were gone...

Still have few nice big Live Rocks around...

New year new Pasar Malam toys...

I had made a major decision in Nov/Dec 2011 to switch to LED technology lightings with the aim to provide a less expensive (in the long run) but flexible and specific lighting environments for the corals.

One of the best things of this new LED technology is the flexibility for me to “fine tune” the intentsity and the colour temperatures of LED Lights based on the specific requirement of the corals (espeically for my SPS). This specific lighting configuration can be stored and controlled with the build-in timer and controller to provide different magnitudes of light spectrum at specific timing of the day or night. For example, to obtain the colour temperature of 20000K, I can adjust the capacity of the two rows of white LED at 99% and the single row of blue LED at 39% on the LemenAqua UltraBrite controller.

For those who are considering switching to LED, here are some information and comparison with MH and T5 for your reference..

.... this is not a Pasar Malam item..

Something had arrived from the land of "world factories"...

Anybody want to make a good educational guess????

[clee123]

Frankly spreaking, I don't think 2 set of LumenAqua UltraBrite LED system (1.5W white LED X 80 Chips + 1.5W blue LED x 40 Osram Chips each set - 180W) can provide sufficient lighting for my 6 feet SPS ominated tank with a deepth of 2.5 feet..

As such, after some researchs and considerations, I embarked on a journey to design and custom build a more powerful main LED system. The following are the specification of the main LED systsem:

90cm x 42cm x 6cm (3 x 30W 15000K White LED + 36 x 3W White + 36 x 3W Blue + 6 x 1W

403 NM Royal Blue) with 3-way timer, temperature controller , adjustable intensity and colour temperature for Blue/White LED.

After 3-4 weeks of anxiously waiting, the system finally arrived before the x'mas in 2011..

The main feature of this LED system is the specificially added latest 3 x 30W ultra brigth 15000K white LED..

Overall, the main LED provides a total of 310W output which, in technically spreaking, equal to, if not better than, the two LumenAqua UltraBrite LED systems.

let me guess from china ?

[clee123]

let me guess from china ?

yeah...

[sunny03]

any FTS pic with the new led light on only .... is there any spot light effect on the 30w led

[Jameshong]

Wat's spec of the LEDs used?

[clee123]

The followings are the LED on 10-20% intensity for initial testing...

The 3 x 30W LED lights were too bright ...

[clee123]

My current LED lighting system is made up of 2 LemenAqua UltraBrite light sets (with 180W of blue/White LED light for each set) and 1 custom build 312W LED Light set (3 x 30W 15000K Superwhite LED + 36 x 3W White + 36 x 3W Blue + 6 x 1W 403 NM Royal Blue). Hence, based on MH / LED comparison, I am theoretically replacing my old lighting system with stronger 4 x 400 MH lights with T5 supplements at an economical alternative.

As a safety measure, I also supplement the current LED lightings systems with 2 sets of 6 feet T5 actinic blue lighting (4 x 39W each set) which I placed at the top of the tank hood...

This is the FTS under the LED system..

The distribution of the light spectrum is quite well spread...

[clee123]

Wat's spec of the LEDs used?

For the DIY LED system mostly are XREE LED :

3W White LED two types:

1) 3W (pure white) - 6500K 180-200lm 3.0-3.4v 700mA

2) 3W (cool white) - 11000-12000k 180-200lm 3.4-3.8v 700mA

3W Blue LED three types:

1) 3W Blue 445-450nm 30-45lm 3.7-3.8v 700mA

2) 3W Blue 450-460nm 30-45lm 3.7-3.8v 700mA

3) 3W Blue 460-470nm 30-45lm 3.4-3.8v 700mA

1W violet LED - 420-425nm 3lm 3.0-3.8v 350mA

30W HighPower White LED - 2700-15000K 2700-3000lm 30-36v 1050mA

Clee from the pic it seem like Blue and white led are in a strip and they are able to control by colours...

have you check with them what driver did they provide you for this set up?

Lastly able to provide us the website that you got this set.

Based on my understanding... each strip of Blue or White Led is controlled by one driver... so where are about six drivers for the blue and white LED... one for the violet 403NM LED and one driver for the 30W HighPower LED.. The blue LED and White is further connect to the dimmer controller. Each series of LED (e.g Blue, White, Violet, and 30W LED) has it own power swithch and all connected to the 3-way timer..

The dimmerable drivers used, I believe is the home growth waterproof less expensive type from SC Electronics (ShengChang) - model no KI-45700-A-DIM ..

Bro suuny03,

My custom made 312W LED system was done by a reefer who I know in cmfish.com where he mades DIY LED as a freelance. Not recommend for fussy reefer and you need to communicate (PM and text) with him in Chinese. FYI, the full set including the shipping to Singapore was closed to S$1000...PM me for the contact if interested..

You will be suprised that China is very advanced in LED technology now and they are very fast at "Copying and improvise with new innovative ideas" just like its "China made Handphone".

For the benefit of everyone who is interested in LED Technology at a cheaper alternatives, I will post are some of my recommendations here....

[sunny03]

Ic so it was build by a reefer...cos i was wondering where he find the 2ways PCB with 4 Leds, so far i can only find 2 ways PCB with 6 Leds.

So far what is the working temperature of this light set as you have 3 x 30w onboard? As high temp will shortern the lifespan of the LED.

After seeing your set.. i am thinking of redoing my LED set to include a few 20W Led ....

There are four cooling fans installed for the LED system..

When all the LED lights are in operation the fans are able to maintain the temperture at 48-46C... The four fans are configured to start cooling the system when the temperture reaching 37C and stop operation when the temperture is cooling down to 35C..

I fully agree with you that keeping a good cooling system or good design of heatsink is critical for LED system... Having a 10W or 20W high power LED is a good choice to start with..

[clee123]

The following is the link to a DIY LED company in China where you can order and build the system based on your requirements and specification. All you need to do is to select your based configuration (dimension, SPS, LPS, planted, or fish only tank) and add additional items (such as temperature controller, timer, hanging kit, addition high 10W LED, etc.) to the shopping cart..

http://ledsea.taobao.com/

The down side is that they don't do system with dimmer control or colour temperture controller.. that's one of the reasons I option for another choice...

It would be good if you can communicate with them in Chinese as they will able to recommend the right lighting requirements for your tank based on bioload and livestock you are keeping or want to keep.. They also started reefing as an hobby and had since grown into business when many reefers get them to do custom build LED lighting systems.....

[clee123]

End of last year 2011, I'd got an opportunity to visit one of the largest Pet and Aquarium show in Guangzhou..One of the main show case items there was LED Lightings...you could feel that there are lots of LED system developments going on and many big players and small player are coming up simple or advanced LED for the fish keeping markets.

The following link is one of the LED manufactureor that caught my eyes.

http://pharosled.en.alibaba.com

The key features of their proudcts are quite impressive (taken out from their website) just to mentioned a few:

1. Initiate the world’s first lighting compensation system, adjust the light intensity automatically to achieve the energy-saving purpose, saving 20% more power than conventional led aquarium light. Save electricity bills, save money for the end user

2. Programmable timer function, replicate sunrise, daylight, sunset and moon light. Moon intensity automatically adjusts to follow the actual lunar cycle.

3. Manual functions. Light intensity is adjustable from 1% to 100%, color temperature and lighting mode can be adjusted at your will.

4. Integrated Wireless Control Module/Controller with followings functions:

1. Advanced Control For Sunrise/Sunset/Moonlight

2. Cloud Simulation

3. Lunar Cycle

4. Dimmable

5. Setting Night Time Length at Your Will

The good thing about this LED manufacturer is that they are in the LED business and Reef lightings is just part of the business sector..so they have the brandwith and capacity to go beyond current LED to, may be, the future OLED technology (which are coming up very soon..)

For those CREE LED crazy guys.... you now have an option...

[clee123]

In my previous post, I mentioned that one of the key drivers for me to swithch to LED lighting is the flexibility for me to "fine tune" the intensity and colour temperture of the LED to meet the requirements for corals at differnt point of time.. This is very important as the quality of lights needed by the corals for photosynthesis is not always the same through out the day. As such, having a constant high PAR value is not necessary good for corals growth..The key is quality of light required NOT quantity of light..

So, a LED system with the added feature that can simulate the cycle of the sunrise (25000k), afternoon (8000k), sunset (25000k), and moonlight is essential. As compared to the earlier LED system, with only one non-adjustable intensity and single colour temperture, the new LED technology is also more effcient in power comsumption. This also translate to additional money saving.

[sunny03]

nice pics

[clee123]

Another essential feature I think a new LED system should have is to equipped with necessary waveleghts and specturm of lights needed for a varitey of corals. As light requirements can sometimes vary greatly, even within different coral species but with the same genus. In addition, two species of corals do not grow at the same rate, when under the same photosynthetic wavelength of light. This is because each species requires a specific color wavelength (measured in nanometers) to obtain optimal color pigment of the corals tissue.

There are some reefers converted their LED system back to MH or T5 as they find that LED lighting cannot bring out the colour of some of their SPS as compared to when they were using MH/T5. I would like to think that this might due to the fact that old LED covered only certain wavelenghs (White/Blue) required by certain corals but not all. So, a LED system with the auxiliary lights consist of red, green and blue color chips, alternating with purple (voilet) and blue beads can provide the greatest degree of spectrum for the LPS and SPS; With special controller of RGB, dozens of colors can be set and the true color of the fish, coral, and tank can be presented, which in my view, completely change the traditional lighting effect.

For existing LED users, you might want to consider supplement the auxiliary lights with the followings:

Alternatively, for those who are considering converting to LED system, a LED light set with auxiliary lights build in is a preferred option.
