Expand Light Spectrum
Testing
Just how can you trust your expand lights? Many of us can not – so we pay a costs to go with high credibilities or adhere to the rumour mill and also risk it. If something goes incorrect with the expand, we might never ever truly comprehend why.
Confronted with this trouble a while ago I made as well as developed a light spectrometer (it likewise covers Infra Red – IR and also Ultra Violet – UV).
It functioned so well that I made a manufacturing variation which I currently market worldwide. I call it “i-Phos”. It markets from ₤ 49 as well as up.
This video clip reveals you just how I utilize my i-Phos spectrometer to examine an affordable expand light.
The verdict in this situation regarding its range of radiation is that it is generally according to its promoted PAR range. I additionally keep in mind that is just a 3rd of the marketed power! That is a various tale.
If you require to recognize the light element of your expanding setting after that the i-Phos can actually assist by informing you what you merely can not see without it – the wavelengths which your source of lights are emitting.
And also it’s not simply resources that you can handle far better – it’s likewise the “clear” treatments as well as membrane layers you might have in your greenhouse – most get rid of particular wavelengths to differing levels and also the i-Phos can actually aid you to recognize what’s occurring right here.

It functioned so well that I created a manufacturing variation which I currently use for sale worldwide. The final thought in this situation regarding its range of radiation is that it is extensively in line with its promoted PAR range.
The light is made up of several different colour lights from the pic, wouldn’t it be more correct to test with all the LED on?
Lennium, as I explained in the video, my bench power will not run all LEDs and since all LEDs are th same, there is no benefit to running them all. The spectrometer can only see one at a atime anyway. Each LED is in fact several LED emmiters in a single capsule, but all capsules are the same, so the text is a fair one. I could test different capsules to see how consistent they are, but I know from other work that they are all pretty much identical.
@Chris Wesley 2 years later, but that’s the power of youtube. I don’t agree with your statement the LED’s are all the same. They look to have different phosphor colors. On this still you can see that: 0:52 . Maybe a cool tip, when you paused a Youtube video, you can step down or up one frame by pressing , or .
@Oscar I should have said “all LEDs of the same colour are the same”.
@Chris Wesley That’s not the point. You did measure one LED, but the whole fixture could maybe get a better result when all different leds are lit.
@Oscar OK it was 3 yers ago. I’ve just re-watcehd it. The assumption was that all LEDs are the same. To be really rigorous I’d test them all, but my conclusion was that they perform in the range advertised anyway, and I don’t think individual variation would have changed that conclusion.
Have you placed this under a commercially sold grow light like a MarsHydro or some other brand hanging over this pointing up as a plant would see the whole light instead of individual led chips?
No I have not done that; I build my own grow lights (viodeos on the channel if you’re interested).
