What is your grow space?
The LED market is flooded with low quality grow lights, they are usually recognizable by the fact that they lie and give way higher wattages than they actually provide.
For example the 'VIPARSPECTRA 1200W' actually consumes only 524w.
HPS or CMH lamps will outperform these lights at comparable wattages.
There are high quality LED lights which are capable of outperforming HPS and CMH at comparable wattages.
High quality LED > HPS/CMH > cheap Amazon LED lights.
There are some manufacturers like 'Pacific Light Concepts', 'Horticulture Lighting Group' and 'Timber Grow Light' who offer high quality LED fixtures for a reasonable price ($1.25/w-$1.50/w) based on white LED.
Companies like 'ChilLED Tech' offer even more expensive builds which are more sophisticated with modified spectra, network control etc.
These are more in the ~$2.00/w range.
Most of the higher quality light meet high safety standards like IP65 up to IP67 ratings. These are especially interesting for commercial grower who are regulated and insured.
Depending on your craftsmanship, you can also build high quality lights on your own and reduce the price to about $1.00/w.
Something like these may fit your situation.

We are playing around with UV leds and was thinking about tubes like this that can be hung in the corners. In our case, would just be UV LEDs to try to increase resin production, but you could supplement any wavelength(s) or just go with the newer all white diodes ( primarily blue ). I recommend a mix, but if your current lighting lacks body in a certain area, just order that colour. Anything is possible with LED, best mix I have found is your typical 7:1 red:blue with a few 2700K and 10,000K whites, a yellow, ( no IR/UV In my main panels) but ultimately depends on if you are just veg-ing or flowering too. For veg use primarily blues or white leds, even a measly 50 watts of LED will veg a table no prob. Save the bigger wattages for the flowering spectrums. Which is where it counts.
I think it was this one but I could have sworn it said 60w on the back.
To build on my previous answer: Does this only really pertain to the high intensity grow lights? Because the one I was thinking of getting was this one https://www.amazon.com/Roleadro-Panel-Spectrum-Growing-Flowering/dp/B01IVQ96KY Which seems to have an actual output of 25 or so watts. So if I hung this on a shelf, and looked the plants on it, would it direct the harmful frequencies onto my eyes, or would it be absorbed into the chlorophyll mostly?
