i found good quality here: vanqled.com

6 in series / and up to 4 in paralell - 24 chips in total gives you best efficiency, better heat management and longlife + ~ 50% more light compared to the use of only 6 cobs@1400mA. If you are able to grow 50% more yield with 50% more light - your investment of ~ ( $ 360,- for 18 chips)...

If i`d pull out chips and drivers of an Amare panel - and mount all on a coolmac-system the light gains 5-10% efficiency only by driving the chips ~ 40°- 60°C cooler. I can hang a coolmac closer to the babies - but the most important reason for watercooling is to use the hot water to...

Each KW I spend with a light-heat coupling like coolmac i harvest up to 0,65 KW of heat.:fire: I do not use oil or gas anymore to take hot showers. :eyesmoke: The money I save in hot water compenses my electricity bill. Amare ~ 25 points <---> Coolmac ~75 points :cuss...

There are different types(producers) of these 1500-1800K chips on the asian market. Some phosphor layers are thinner than others and so emit more blue and higher lumens/W. driving them @ low (25-33%) current - offer an easy, cheap and efficient way to veg. and bloom with a single spectrum.

This is not output voltage - it`s input voltage in case of dc You can`t drive those chips with this driver - because HLG 600H 48A has dc output of 48V Better to buy eg. 2 x HLG-320H-C1400A

:peace: Make sure both cobs have ~ the same Vf. So the current will be devided ~ 50% / 50%. Take care of an efect that happens if one cob get much more current than the other: - He will get hoter than the other cob --> Vf will go down with the rising chip temp. - and this cause aditional...

Because your chips run at low Tj. ---> Vf is rising with low Tj. When i drive a 50W cob with 50W driver(1,5A @33,3V) on an aircooled heatsink, my powermeter shows ~50W. If i mount the same led and driver on a coolmac-system with direct contact to the (15°C) water - my powermeter shows ~55W...

If your grandmother or any other member of your family should die whilst in the shelter, put them outside, but remember to tag them first for identification purposes When you hear the air attack warning, you and your family must take cover at once. .. maybe one of the last things... they order...

Sorry ty - the cheapest fusion power source is the sun - and only 8min. away. In my religion she is in the center - and master of desaster and fertility. (: She (: is the only GOD for plants and animals like us - don`t believe in the stupid popes and other religions and theories - as long as...

Do you know that you can triple energy efficacy of your led lamp. Watercooling with very low Tj (25°-50°C) and up to 85% energy efficacy. Cheap heat exchangers available everywhere. 300W lamp(15h) can produce 80L of hot water. I can give you support to buy your individual needs. You`ll find...

Send them to the white house by fedex ! :cuss::fire::wall: Guerilla-growing is naturally the better option :leaf::leaf::leaf::leaf::leaf: :weed::leaf::leaf::leaf::leaf: give them a chance with a car it shouldn`t be a problem to find a good place far away ! live is risky or put them in the...

"Hell" sounds for me much better !!!

:peace::bigjoint:Have a look to this product ! 20 years of anti-corrosion protection / ecological and cheap. greetings to your tilapias

:bigjoint: have you ever smoked a carrot ? Cut a carrot on the length in 2 pieces - pull out the string of the center ! Now put it together again and you got something like an indian chillum. The combination of a good hash or weed with beta carotene help your eyes to see - specially in the...

:bigjoint: "she" wraps just all and everything in plastic or latex - to make you pregnant. o_O "Her" avatar shows clearly, that "she" is the easter bunny on "her" easter walk. Please make shure to use colored plastic bags and condoms. (:

The chip and your heatsink can get destroyed easily. Use thermal grease (often they have better heat conductivity and can get to thinner layers than glue) - clean the outline and " secure " your chip with 4 points of a hard adhesive for metalls.(eg. super glue) If you want to change your chip -...

:peace: Make shure not to mix up aluminium and copper in your cooling loop. You can buy aluminium - or - copper radiators. Chose the same material you find in your heat sink. I think its a good idea to give your heat exchanger a layer of electrically insulating - before you hang it into the...

:peace: Do you ask about the watercooled lens - or do you ask for Coolmac lamp build ? (:

you can always repeat your lessons - go back and read - till you understand the difference between luminous efficacy of radiation and light efficacy. You still - don`t understand the main difference between the luminous efficacy of radiation and the luminous efficacy of a source. That means the...
