Tapi sekarang tarak H/P, jadi tak leh semes. Jadi wa kena tunggu lama beb..

Yang mana satu Maznah..?

Need to use aluminium sheet which acts like a heat sink, preferable more than 3mm thick. If you can use those heat sink which looks like butterfly , is better because the greater surface area to conduct the heat away from the LED, but expensive. Also, need some sort of heat grease to have excellent contact with the LED and the aluminium sheet. Then of course you need fan with suitable CFM to extract the heat out.

Ya bro.. the LEDs are really good on the corals too. I have programmed to switch on about 60-70% royal blue first, then combination of blues and white for total of 70%, then the final timing is to switch on 100%. When the royal blues are switched on, the corals really glow, especially the hammers, purple anemone, some sps, but of course the fishes look so dull. When all the lights on, the tank colour looks like 14K. I am still not accustom to the percived lower lighting levels viewing from the front glass. But from the top, damn bright, like my 2 MH lights. But overall, I am happy that the chiller doesn't have to work so hard now, and I have also cut down the total lights consumption by 15% and I could see the electric bills will come down, even when the tariffs are up Also save on top-up water since no more MH to boil the water.

Hi Bro, Good that you want to go green by LED'ing. You can either go by easy method or difficult method. Easy method is just buying the complete set with warranty etc, from our sponsor or the difficult method, which is DIYing. Of course DIYing can save lots of moolas but lots of troubles doing soldering, troubleshooting, heat issues to overcome, etc, etc, but still very doable by anyone.

Hi bro, Attached is my LED layout. The top right corner is where my overflow box is, so no need to put any LEDs. Since my tank is 2.5feet deep, to penetrate deeper, I use the 60deg lens for those areas that need the extra reach, which are at the fronts LED_wirings.pdf

You should see the light spectrum. I think much better than the MH or T5 at the blue region. Since the LED intensity is getting brighter, LED is a way to go for reefing. On top of it, the heat radiating from the light to the water is extremely low, so the chiller will run lesser, maintenance of chiller is lesser, electricity bills is lesser. I've seen my chiller work less after installing my 129LEDs for my 3x3 mostly sps tank. Before was 2x250WMH + 6x39W T5, when everything on, chiller need to run 3 hour to chill from 28 to 26 degC, Now, with full LED on, run about 1 hour, same as when all the lights are switched off.

Muka nyer sweet, tapi bawah ketiak sour kot..

maznah mana pulak... cuba upload gambor... biar terang sikit..

Apalagi .. stun la...

Abis... nanti wa nak kontek lu amacam..?

Hi Bro, Thanks for sharing on your LED DIY and breaking down the costs. I do hope more reefers would start using LEDs whether by buying off the shelves or DIYing as this will definitely trim the maintenance cost.

When are you going to start? Save electricity, save $$$, save earth...

Hi Bro.. Nce works, very pro... Just wanna ask you... What's the spacing between the LEDs? May be you might want to shift the connectors to the top so that the salt spray do not easily corrode the metal parts at the sides.

ala.... si dia tu la... macam tak tahu jer...

eleh..aksen tak nampak konon....

oh itu wa rasa yang jual keropok kat block2. Sesapa tak pegang bendera betul2 nanti kena pukau..

For a thought, the thread title meant that angel fish eating the roti prata bought from the shops...

Lu kalau tak mau kena plus senang jer... Sebelum dia mau plus lu, cepat2 tu tunjok dia .. Eh, ada bas terbalik kat belakang sana... bila dia pandang belakang, lu pun tukar dam lu punya tempat la..

wa itu soalan cepu emas... wa rasa computer dia ada built-in hp...

oh gitu.. lu pun dah try?

Wa rasa ini ubat kuat ... Lu makan lah.. nanti national day, lu boleh pegang bendera tu mesti tegak punya...
