LED distance questions


Active Member
hey guys i have a few lighting question about different led's

when it comes to led strips, alluminium channel bar, led bulbs and led grow panels. do they all need to be kept a certain distance from the plant or does the different light setup make for different distances. Here are a few i was looking at and was wondering if you could help me the right distance between them

1.Aluminium Channel Bar Light 12W

Technical details:

LED type: SMD5630
LED Quantity: 36 LEDs
Light Beam Angle: 160 degrees
Life span: 50 000H
Wavelength: Blue 450-465nm (12LEDs)
Red 620-635nm (16LEDs)
Operating Voltage: 12VDC
Power Consumption: 12W

2. Led full spectrum grow bulb

Technical details:

Voltage: 85-265V
Body Material: Aluminum
Power Source: AC
Light Source:LED Bulbs
For: Flower Plants,Hydroponics and Vegetables
Item: SMD 5730 led grow light
Base Type: E27
Full Spectrum:
Lumens: 2500-3200LM

So between these to led grow lights. what is the distance they need to be kept from the plant. I know the big boys like 300w and up grow panels need to be kept between 12-24". does this apply with these two lights aswell

thanks for any input

For thoes small lights I'd do 6inchs. You'll be able to tell if it's to close not going to kill your plant.

Okay cool, thanks for the feedback.. After calculations.. I should be able to grow a plant with one of these to choices in my grow space.. The height is 115cm.. Minus plant and container height i should be left with 25-30cm of space from top of plat to cabinet roof.. Thats roughly 10 inches of space between plant and light.. So i was thinking either 4 led bulbs or 6 led bars.. What you guys think.. Keep in mind later i will be upgrading to a grow tent of 60x80x180cm with a 600w full spectrum led panel. But that will only be in a month or two due to long shipping times from over seas.. So as a little experiment.. Is my idea a good one or should i scrap it?

I use led panels, (2xGroHydro 300's), and I keep them at 8-12 inches for clones and seedlings then raise them to 18-20 for veg and flower....

Well after this current grow i have got going im gonna move over to a tent and a 600w led panel.. Untill then i was just wondering if i could use these leds in my much smaller confined grow space..

Hey guys, here are some pics of my girl thats growing outside seeing as the lighting schedule is at bloom so to say all natural..


I trimmed her today which i know is not advised but i didn't want any popcorn sites so to speak.. She is getting the same feeding schedule as my indoor plant.. As you can see i should have 5-6 main cola spots..

I also did stock up on more wiring and plugs and so on for my indoor plant which i will update later tonight..

Here is to a happy grow..

Okay some im still doing some research on lighting and so on.. I come across the following led lights and wanted to know if this will be worth while adding to the sides or even the top of my grow cabinet.

Technical details:

LED type: SMD5730
LED Quantity: 3LEDs
Light Beam Angle: 120 degrees
Life span: 50000H
Colour: RED
Operating voltage: 12Vdc
Power consumption: 1W
Size 75x12 x 0.5mm

I contacted the supplier and she said its in the 630nm red spectrum.. As for light penetration and plant distance she could not answer me.. So what you guys think?
