led growlight 44watt with fans

[Thinklast183]

will this work?

[Thinklast183]

please help. i'll have 100 red forward volt 1.8 to 2.2 forward current 30ma. 44 blues forward volt 3.2 to 3.8 forward current 30ma. what resistor will i need. this should make 12x12. And will my input 100 to 240V 2A, 50 to 60Hz DC output 24V / 6.3A, 150watts max. Thanks in advance.

yo. im about to make one from 24volt dc charger? with 100 red and 44 blue. already got the array wire diagram. will the charger be enough?

I got mine from JacksBargainBin and in 660NM which is the range you want to flower in.

Great song selection for this type of video

brilliant

[sam91832]

These videos are brilliant. I am glad i saw them before i began my led grow light project otherwise i would have kept burning out my leds. I dont have a clue about electrics but am gathering info to make a high powered led lamp. Could you help me with some information on how i would go about starting next time your not busy. I am unsure of many of the names of things i need. I know i need 3w leds in red and blue and the plug part of a pc and some fans but not sure what else and how to combine.

i see your running this on a computer power unit,how much volt os coming out of those?how many leds does a computer power unit run?

[viilips]

im not using right now, im waiting for them arrive.. :)

there will be 50 LEDs on 100ma and 100 LEDs on 25ma

ok, so for 25ma i will use yellow violet black resistor

and for 100ma i will use brown red black resistor

thank you about fan advice...

without u i would be lost :D

hmm, but i cant understad - why for 5w and 3w LEDs is not required fan, but for 10mm leds is...

[hopeitshappy]

thats ok if u need any more help just ask

u will have to wire them up 3 leds per string and then a resistor so u need 1 resistor per 3 leds

the 3w's do get very hot im using a large heat sink 3 kgs of ali and 4 pc fans and they run at about 60c

[viilips]

yes, but normaly it doesnt require cooling? cuz im growing with my 5w led a month or so, it didnt melt or overburn, its working great, cant wait for my 10mm leds to add.

but yes, 10mm is from plastic, it could melt..

if you take a look at 3w or 5w light bulbs, they dont have no cooling in it, right? :) but cooling may be good for flowers wich is grown with leds. :)

[viilips]

leds can overheat?????

[hopeitshappy]

yer these are 0.5watt

last about 5mins on before they start to melt

[viilips]

so i must use coolig for these LEDs, right? *Low Power Consumption *I.C. Compatible *Intensely Bright *Source Material: Algan *Emitting Colour: Blue *LENS Type:Water clear *Luminous Intensity-MCD: Avg:50000cd Max: 70000 mcd *Reverse Voltage:5.0 V *DC Forward Voltage: Typical: 3.0V Max: 3.8V *DC Forward Current:25mA *Viewing Angle:12±6 degree *Lead Soldering Temp:260oC for 5 seconds *Led lamp size:10mm *Viewing Angle: 12 Degree

[hopeitshappy]

these leds are only 25ma i wouldnt think they would get hot

the 100ma ones get hot

[viilips]

and what kind of resistors i must purchase for them? (12v)

[hopeitshappy]

for 25ma leds try

47 ohm resistor 1/4Watt or 1/2watt

yellow violet black

they will need to be 3 leds per string

[dingsimon114]

what's the supply voltage and voltage on each LED. What's the color of your LED.

[hopeitshappy]

these need cooling the leds will over heat

there not hot enough to warm a room

[kildevlin]

Totally superfluous. The heat generated by these lights is nominal. But even if they did radiate a substantial amount of heat you would want to have ducting to exhaust it away from your grow room.
