DIY DIY 60w LED veg light 5400 lumen

[KsjAuto]

@ KsjAuto You should check out the 30;50 and 100w multiband & multichip LED arrays Epistar produces now. Very nice! :High 5:

@ lowbudge

Landrace Malana Seeds are constantly available at RSC, I still have 3 in my fridge from years ago :

Thanx for the info,,
The cost price on the high power led 30-100 watt is to expensive W/$
the rgb "multiband" you don't know what kind of nm wavelenght the output is without a spectrophotometer.
im working with a dr40 tent 40-40-120 cm so heat is an issue with high power led.
These led get super hot like burning hot:

:smokebuds:
Peace

Mind share some links? i'm "lazzy" ^^

Hi
I bought the leds on aliexpress

This is the manufacturer if anyone wants more info about the arrays.
I had a link to a german site that sells them, but Red removed it, I will only post it again if approved.
Anyway they are not typical RGB arrays, these are just 1W LEDs cramped together.

Lichtfarbe Wellenlänge Anzahl
IR 730nm 5x
dunkles Rot 660nm 23x
helles Rot 630nm 11x
Orange 590nm 1x
helles Blau 460nm 5x
dunkles Blau 430nm 4x
UV 380nm 1x

Wellenlängen (Spektrum): 7-Band (siehe Chip-Konfiguration)
Leuchtquelle: 50x 1W LED Chip Array
Flussspannung: 22.0 - 26.0V
Konstantstrom: 1750mA
Leistung: ca. 50W
Lebensdauer: ca. 50000 Std.

From the site. I wouldn't use them for any large area. But for small stuff these are nice. If you get the driver and heatsink somewhere else, you could build 2-3 30w lights for the price of one CultureLux 30w light. You also get a more complex spectrum.

I want to build a cab half for photo motherplants and half for some autos I'll toss in from time to time. I might build some lamps with those arrays, would be nice to place one of the multibands over the autos, and one of the blue/ red over the mothers. I'll keep you posted if I get them.

:tiphat:

To super mario
keep us posted
i just had a look at the mutltiband "not rgb"
That looks interesting. seems that i might have to look out for that company see whats comming out
Peace

I do if I can. But I can't promise anything. Money is tight, and I have to invest a lot. Also I already have some LEDs that would suffice for the mothers and cuttings.

Yeah but I'm personally not a fan. I could buy a decent 100-200W light for the same price.
I would think about it if there was something special about the lights, but the design is very minimalistic.
I'd rather build some myself ( even by starting with indiviual diodes from zero ), and get the extra fun & experience on the top for free .

 

[KsjAuto]

Minimalistic ore not
its the only led i seen with passive cooling = ZERRO noise
so if noise is a issue what kind of led can you find ?
Anyways it will always be more fun to make things. than bying things

I heard somewhere that for passive cooling led you need approximately 30 grams of aluminum per watt, do you guys think this could be correct?
