Need help with ratio of LED, regards to lumen

[sexycybe]

Hey all, first post on this site, usually use another but there is way more info on LED lights here!
Was just after a little bit of advice.
I just ordered my LED lights and was wondering how i should wire these up.
I bought:
8 x 6500K cool white
4 x 430-440nm
8 x 450-455nm
4 x 620-630nm
16 x 640-650nm
12 x 660nm
4 x 730nm

I know that the lower spectrum (430-455nm) lights are more beneficial during veg growth and the higher spectrum (620-730nm)are more beneficial for flowering.
Should i wire it up so during veg growth only the whites and 430-455nm are running and when flowering only the whites and 620-730nm are running?


Also i have just noticed some of the lights emit different levels of lumen. should the ratio be in lumen?
A ratio of:
1 x 430-440nm
2 x 450-455nm
1 x 620-630nm
4 x 640-650nm
3 x 660nm
1 x 730nm

Seeing as the lumen are as follows the number of lights shall be:
15lm 430-440nm
50lm 450-455nm
80lm 620-630nm
80lm 640-650nm
70lm 660nm
20lm 730nm


21 x 430-440nm
13 x 450-455nm
4 x 620-630nm
16 x 640-650nm
14 x 660nm
16 x 730nm

Are the 730nm all that important that that many are needed?

Thanks for the help

forget lumens.. that doesn't matter

veg run all of them

flower you need warm whites, cool whites are a no no. or you need to cut the CW and some of the blue... honestly, I would have done all whites, maybe some red for a panel, simpler setup



we would need to see data sheets to know how to wire them..

 

[sexycybe]

Thanks mate, i was just wondering whether i should wire all the LED so they all run at the same time or to have the option to turn some off (for flowering).
So i will need to wire some of the blues and the whites in a separate circuit so i can turn them off?
Do you think i should get some warm whites?

Also do the LEDs get glued straight onto the heat sink?

The same sight has some:

CCT: 3500-4200K
Color : Warm white
Intensity : 200-220LM

This type?

I need data sheets, you can't mix different chips if the voltages don't match well..

that's dependent on what drivers are available and what voltage the led's are using at what amp..

what size area you running?

you can "glue" the led or use already drilled heatsinks, or drill heatsinks yourself to hold them down with screws. the glue down is permanent and non removable..


wrong WW. you need 2700k or 3000k. those will start having too much blue again.


honestly, if your a noob, I would keep it simple. drop the colors, and use whites, maybe some red in flower.. I'm not a noob and I even use all white..

tell me size first, so I know what your wanting / working with

I was going small but the company that i ordered off put my order through twice (payed 1/2 price for the second as it was easier for them apparently...)

I have two heat (can order more) sinks made of aluminium
300mm x 140mm x 20mm

I have the following lights with the following specs:
8 x 6500K (

8 x 430-440nm
Intensity : 15LM
Voltage: 3.2-3.4V
Current : 700mA
Power : 3watt

16 x 450-455nm
Intensity : 50LM
Voltage: 3.2-3.4
Current : 700mAV
Power : 3watt

4 x 620-630nm
Intensity : 80LM
Voltage: 1.9-2.3V
Current : 700mA
Power : 3watt

16 x 640-650nm
Intensity : 80LM
Voltage: 1.9-2.3V
Current : 700mA
Power : 3watt

12 x 660nm
Intensity : 70LM
Voltage: 1.9-2.3V
Current : 700mA
Power : 3watt

4 x 730nm
Intensity : 20LM
Voltage: 2.1-2.3V
Current : 700mA
Power : 3watt

 

[sexycybe]

Sorry missed:
6000-6500K
Intensity : 220-240LM
Voltage: 3.2-3.4V
Current : 700mA
Power : 3watt

 

[sexycybe]

Found some 3000k LEDs
Item: 1-3W
Emitting Color: Warm White
Lens Material: Resin
Wavelength/CCT :3000k
Luminous Intensity :120lm at 350mA ,220lm at 700mA
Viewing Angle :140degree
Chip array:1
PCB:Ceramic
Forward Current:350-700mA
Forward Voltage : 3.0-3.4v

 

[habeeb]

thanks for the data..

what size setup are you wanting to grow in?


any chance to link me to the page of chips... these seem like cheap chips, and would thus give you cheap performance.

 

[sexycybe]

Yeah sure,

I sure hope they are not!

The size is 1m by 2m but don't necessarily want to use it all

Of course he can mix them. Wire it up in series and the voltage doesn't even matter.

 

[sexycybe]

yeah thats what i thought i meant should i wire the panel so i can turn some of the red/blue on/off and if so how
I can always make parallel circuits of the 2.3V and different ones for the 3.4V

 

[tebos]

Two different circuits/drivers is the easiest option, I think. Look for Mean Well drivers, they are cheap and offer good quality (from ebay, aliexpress).

 

[sexycybe]

Yeah but should i enable it to change the ratio of lights?
What would the ratios of each be?

 

[habeeb]

hey , let the grand master ( tebos ) help you then. he knows so much



good luck......

 

[sexycybe]

Dude, there is no need for sarcasm.
All im after is some help, the more people that have an input the more ideas.
What are your recommendations seeing as i have already bought the lights and cant afford to buy a whole stack of warm lights?
Thanks SxC

I don't know what your problem is. A constant current driver delivers a certain volt range, therefore you can mix LEDs with different forward voltages, it's just plain wrong what you're saying.

@sexycybe: Maybe you could seperate a very red and a more blue circuit, running with 2 drivers and switch them on to supplement each other(flower) or off (veg).

 

[sexycybe]

so maybe run the whites in both the veg and the flower
Run the blues and a few reds (all infareds aswell cos it helps size) during veg
Run the reds and a few blues in the flower
?

 

[tebos]

To be honest I don't know if white only or red/blue is the way to go for.
If you'd go for white only, seperate warm white LEDs (flower) and a few cold/neutral white LEDs (veg).
If you'd go for red/blue/white, go for a light with ~25% blue and one with ~50% or so (numbers are taken because of their widespread use) and turn them on like you need them.

 

[WeedIsGod]

Should i wire it up so during veg growth only the whites and 430-455nm are running and when flowering only the whites and 620-730nm are running?

You bought everything already and you can't change that, but to be honest I don't think it's necessary, or even well warranted. What you wrote right there sounds like an awesome plan to me.
