for now i only have white led.. for marine i think you need some blue led rite?
btw not so hard to built it... if get proper material..LED, power supply and LED driver (constant current). in my project i DIY the driver.. commercial driver so expensive for me.

if i not mistake, you also join chuisui forum rite.. i saw couple of people make & sale LED lighting there..

thx michanz for the shrimpsssss

Yea i saw in chisui too... i think i can go scout out for LED in pasar road.. if still cannot, i'll buy from ebay la.. those 10W or the 20W pun jadi la.. but same price.. but pooki the shipping so damn high.. let's see if they can combine shipping...
i have power supply.. proper one.. 24v DC..

what about LED driver? how do u diy that? what component needed ?.. let me know i'll see if i can source out for it..

10W or 20W? wow.. i dont think you can get it from jalan pasar.. but you can try la.. i suggest you go to shop called online component.. opposite plaza pudu..and also shop beside it i saw they also have reflector for led..

led driver i make it refer to this circuit
http://www.instructables.com/id/Power-LED-...nstant-current/
it's because led more depend on current.. get spec for the led..and power supply..then we can discuss/brainstorming.. heheee

interesting project i saw here...
http://www.aquaticquotient.com/forum/showt...-CREE-LED-Light

michanz got extra shrimpsss to give away?? can donate some ah?

experiment on LED, I have read a lot on LED for planted tanks, so far, has anyone gotten their hands on LED lights for planted tanks?, I am seriously curious if the light is good enough for plants, this is probably the most worthy DIY project

nice one... i'm sure the components are not a big deal.. let me source for the LED at the moment.. and decide how many LED i need to use.. do u need any? let me know how many u need..

i was really thinking of using 10W LED.. and and secure it to the light casing using thearmal grease.. so no need heat sink... alright then, let me know how... worst come to worst may need to buy LED from online leh...

if u just get from online inform me the price, maybe i'll tumpang sekali...
cheaper alternative get from china supplier.. seriously cheap.. as for me 3W led just few cent usd only.. US$0.80 if i not mistaken..
but for quality compared to Luxeon, CREE, or else.. i dont know la..

and i dont think your 10W led will be ok without heatsink.. because my 3W led too will heat up although i attach it on small heatsink (take from broken PSU)

i have this..





but the output is 4.5 A.. we just need a couple of resistors to regulate the voltage and the current.. i don't think we need mosfet and transistor.. one resistor in parallel to regulate the current and one resistor in series to regulate the voltage... we're done...


and this power supply i can get for about 60 RM la..

haaa... one question here is which one better? use resistor or transistor...

anyone giving/selling glosso? would like to get some

and also another question is seachem comprehensive plant supplement suppose to look like this color?

Yes, and it has a foul smell too...

hmmm i was afraid of putting it in.it smelled like rusted metals @@

yup... no doubt that is seachem flourish...

hahaha yea... excel smells kinda sweet...

o_O looks scary. I only got seachem excel, nitrogen, potasium and phosphorus. Didnt get the flourish, planning to buy actually
