The fans are so style, bringing out the young days back in me

Loving the water ripples caused by the fans
I understand shadow's point of view, as I have a similiar situation in my previous diy set up. Slowly 1 by 1 the led start to burn out. Probably next round of diy I'll try led drivers instead. In the meantime need time to slowly source for a cheap high voltage driver to go for higher wattage led set in the future.
Having loads of fun starting from scratch and work all the way to a working lightset is freaking awesome feel. I'm sure all DIY fanatics agree

Dont think you can find higher Voltage Drivers. LED is DC, High DC is very dangerous compare to AC.
More specifically, peak voltage greater than 42.4V is hazardous; voltage less than or equal to 42.4V, or SELV (safety extra-low voltage), is non-hazardous. It is difficult to know when electricity can cause serious injury or be fatal. Contact for only 1 to 3sec with currents of only 6 to 200mA can cause electrocution by disrupting the normal rhythm of heart muscles, resulting in fibrillation and leading to death

All varies from person to person .. it is very individual ..
Shadow, i donno about your circuit. I burnt a few LEDs but when I tested others in series still working when connected to a power supply. I am using 1w , 3w , 5w and now 10w

You can use a LM317 IC to wire a constant current circuit. I did that but find it unnecessary.
Now i salvage my old PC PSU stripped out all the useless 5V supply, and other wires. You can see in the pics only yellow and black cable. And also shorted the Power On.

Do you have cover for the led to prevent water splashing?
I don't have a splash guard. I'm more worried about the water evaporation though. Hence the fans also serve a purpose to provide more air circulation

That interesting, I connect 12 led in series with LED driver, like pic below only with 12 LEDs instead of 3. After about 2 years 2 of the LEDs spoiled but the other 10 LEDs still light up. Both spoiled LED tested short. maybe it is part to part or vendor to vendor variation, mine are from CREE.
We are both right...

LED are parallel connected. Lower Voltage but draw high current safer.
Power = Volt x Current.
48W = 48V x 1A or 12v x 4A
So you can run the same led with a 12VDC source. Rather than a more dangerous 48VDC source.

Also when connect led in parallel, 1 led burns will not cause other led to black out.
High current mean high wattage, component used to make them are larger and they dissipate lots of heat which some requires metal casing to help dissipate off the heat.
If you need 200w led, you should consider flood light. Much easier to DIY just need connect cable to 240v main supply. You may need to think of way to hang it. They come in 10w, 20w, 30w, 50w and 70w.
Honestly to wire 3w led to get 200w is very big job even with 5w led is like 40 leds to wire

Super power 12V adaptor and don't look so ugly
