Bro take measurement from the LED solder point. That should not be more than 40 Deg C if I remember correctly

OK.Thank You Cheers

I like to conclude this constant current driver can easily drive up to 8 LEDs as claim at 680 +/- 20 mA. With more LEDs it still can drive but the intensity fall

Next power up 12 P4 white. A noticeable drop in the light intensity. Around 400 mA. For many others I test it either start to blink or cannot even light up. This is the only constant current driver that can still light up at lower intensity

Next power up 10 P4 LEDs Still not much issue. Look like a little drop in intensity.Maybe around 600 mA

Do a test last nite. First power up 6 P4 white. No issue

Bro, What is a aqualifter pump? Where you stay? Sherman

Check already. He live very far from me. Anyone know how I can get to his place from Bukit Panjang? My place have 966 go to Parkway Parade. After that how to get to Bro Fuel place? Can PM me Cheers

Have free meh? Buying from anyone who have spare pieces

Will check around. So far I never use 1000 mA. I find the heat dissipation is not easy.

It is just another application for LED

If have enough volume then can negotiate for good price.

Want to Get

Testing now. Must make sure it can work as claim then order in. Once confirm will keep in inform

Great thread.Like to join the crowd to try building an algae scrubber I have a 4ft by 2 ft by 2 ft main tank with a 15 inch by 30 inch by 16 inch sump Total capacity = 149 US Gal Recomendation for the algae scrubber screen is 1 square inch per gal of tank water Hence we require 149 square inch of screen for the algae scrubber to work efficiently The sump is 14 inch. We can have a 12 inch wide screen and length of 12 inch or we can had a 5 inch wide screen with 30 inch length Santa am I right in the screen size?

Oop some error in the calculation My 4 footer total capacity =120 US Gal(4x2x2) My sump= 29 US Gal(14x30x16) Total capacity = 149 US Gal Recomendation for the algae scrubber screen is 1 square inch per gal of tank water Hence we require 149 square inch of screen for the algae scrubber to work efficiently The sump is 14 inch. We can have a 12 inch wide screen and length of 12 inch or we can had a 5 inch wide screen with 30 inch length

The overflow compartment

The very crowded sump compartment

My 4 footer total capacity =120 US Gal(4x2x2) My sump= 5.7 US Gal Total capacity = 125 US Gal(14x5.5x16) Recomendation for the algae scrubber screen is 1 square inch per gal of tank water Hence we require 125 square inch of screen for the algae scrubber to work efficiently The sump is 14 inch. We can have a 12 inch wide screen and length of 10.5 inch or we can had a 5 inch wide screen with 25 inch length

Below is the Constant current driver as promise last week The direct AC constant current I just receive from supplier. Will be testing it over the next few days and feedback result. This unit claim can run 7- 8 3 watt high power LED in series. Watch out for the test result

Anyone have the above for sale? Must be adult Sherman 90670590

After completing the nano LED lighting decide to do something the home can use and also help to reduce the electrical bill I build this 4 ft LED light strip.

Di you take the PO4 and NO3 reading before using the scrubber and after implementing it

Scrubber size is base on your water volume. So maybe smaller than most of the above equipments Algae do not have unpleasant smell.Skimate are not algae. This is what I think Maybe someone with working scrubber can help
