Led help please. Looking for some help understanding LED specs

[Yesyes3000]

Hi everyone I’m an just wondering if somebody’s can help me to understand the spec statts on led lights ? For example

• Forward Voltage 48V
• Drive Current typ 500ma, max 1200ma
• Lumens: Typ 4500 Lumens at 560ma, 9000 Lumens at 1.2A
• Cree or cri
• Other important info

I am really interested in understanding exactly what I’m looking at when it comes to led lighting and just growing lights. I found a page a few weeks ago that had some info but I feel like there is probably a good chance that someone here could break this stuff down for me and make it easy to understand. Thank you for you time . Truly grateful
Sincerely 3000

Voltage X Current(amperage) = Watts.
Lumens is brightness as a human eye sees and C.R.I. (CREE is an LED manufacturing company) is for Color Rendering Index meaning how close the spectrum is, relative tool the Suns natural spectrum or "Color".

1200 umol/s with an efficacy of 2.53 umol/j.

3500K and 660nm balanced white-light full spectrum

What does “umol” represent umol/s & umol/j
Also 660nm. What does the “nm” stand for ?
Thank you

UMoles per Jule. NM is for nanometer indicating the wavelength, or COLOR of the light in the spectrum. There are NM outside of visible light. Both past 720 being far red and infra red into gamma rays and UltraViolet

farted and infra red into gamma rays

I was just talking last night about since we are throwing darts at a board pretty much. Why not a gamma light?
Bruce Banger grown with a gamma light. Hulky green buds, the Gamma X.
It will probably kill you though, js.

umol is a micro mol of light photons in the PAR range(400-700nm)...so WTF does that mean???
PAR, PPF, PPFD???
PAR is light wavelengths that are within the 400-700 nm range. This range is what most plants use to grow. PPF(photosynthetic photon flux) is how 'much' PAR in micro mols(umol) a fixture can generate each second. PPFD(PPFDensity) divides that PPF value by the area(in sq meters) you're trying to light to give you an average intensity over the entire area.
umol is just a metric for how much light you have. umol/j is the metric for efficacy. It describes how much light a fixture generates for each watt(j/s) of power used. Your example generates 2.53 umol of PPF for each watt applied. Bigger is better here-more light for each watt.

Go to the California lightworks website and look up How do plants use different light spectrums..it explains what each color does for all stages of growth and how much nomes is needed to increase thc potency aroma flavor etc.good info and they also have high quality lights so you know they are highly priced.
