Here is a link to a generic chart: https://www.led-professional.com/...10019e.png

Essentially, plants mostly need certain wavelengths of blue and red light (Hence why grow lights are usually purple when turned on). Wavelengths not used by plants dont do any harm, they are just reflected/not used. Green light for example, is not used at all. Which is why plants look green, the green light is reflected to your eyes.

Your typical shop lights are designed to mimic the color of daylight/warm white, and usually end up heavy on the green/orange range. You would be missing the critical blue range. This isnt to say a shop light wont work, it just wont work well, meaning you have to have more lights at closer range than a properly designed light.

All plants are different too, some dont need certain wavelengths that others do.

Get the hyper tough 2pk shop light for $18. Keep them extremely close to seedlings making them not stretch and become leggy. Zero issues for me. Then use a small oscillating fan to get them used to wind. Then harden them off slowly on overcast days

I've seen people using regular fluorescent grow their seedlings without any issue so I don't understand what advantage these lights have to offer in terms of crop yield. I'm trying to see if it would be worth $120 to outfit 4 shelves.

Not an expert gardener, but I'd say a full spectrum light might be needed to grow plants entirely indoors from germination to fruiting /flowering. I myself have used a 4000k light for seedlings all the way to bringing them outside in the spring no problem

I'm using the 36" for my aquarium plants, they all have new growth and are doing well so I think it's working well.

The main draw of these vs fluorescent tube lights is power consumption and heat. FL provide a more gradual and broad color spectrum where LEDs are going to be targeted intense wavelengths. You can find charts online that demonstrate this. Some uses it works great, others need the broad light. LED gets around this by using multiple wavelength LEDs in their setups.

I've wondered how the 'grow' labeled lights compare to general shop lights. If this is equally effective, then that's a cheaper light per light it looks like.

Overly simplified answer:

"grow lights" or 'Targeted Spectrum lights' have a purple-ish looking glow that targets the wavelengths for plant growth

'full spectrum' lights include parts of the spectrum that plants don't need.

If you look at the color graph for Grow Lights, you will see that the green and yellow colors are notched out.

The PPF value for the 36" is 44

So when you say 'parts of the spectrum plants don't need', that sounds like there's no detriment or that anything is lacking, by using lights that aren't specified as 'grow lights'? Then, wouldn't any white (or essentially white) light contain all (or most) of the colors on the spectrum?

So specifically to the question whether work shop lights are just as effective compared to specified 'grow light', it sounds like the answer is likely yes??

Is it just a matter of intensity/brightness then, as long as lights are white?

Curious where did you find this? And is this a good or bad value for this size light?

Most likely no.

Less effective because you are wasting power in needless parts of the spectrum.

Less effective because you likely have very little output in certain parts of the spectrum that plants require.

So these are basically 3000K lights, jacked up and being sold as "full spectrum" grow lights?
