"Best" is a relative term. Everything comes at a cost. The question is what cost are you willing to pay to get what benefit? Overall cost (in dollars) is one factor, heat produced is another, longevity of the lights is another, quality of the light output is another, modifications necessary to your current space is another . . . you get the idea. Plus, what is best to grow orchids isn't the best to grow cannabis and isn't the best to grow CPs. There's considerable research done on light requirements on cannabis and other cash crops typically grown indoors. Less so on CPs overall.
But to point you in the right direction, on the low end of "best" I think it's hard to beat any one of these: https://www.amazon.com/GE-Lighting-9310 ... r=8-5&th=1
. Very good light output, good quality, good lifespan, low cost.
A step above that would probably be a Monios system (https://www.amazon.com/gp/product/B07QF ... 94ef6&th=1
or https://www.amazon.com/gp/product/B07QJ ... 15b530a241
) or a Barrina system (https://www.amazon.com/gp/product/B082Z ... c1339&th=1
). Costs more, but light output is better. Comes with more heat which may have some associated "costs."
Next is probably a Mars Hydro, Spyder Farmer, Bloomspec or other comparable model (https://www.amazon.com/Spider-Farmer-Di ... B07VL8FZS1
, https://www.amazon.com/dp/B07VL8FZS1/?c ... _lig_dp_it
, https://www.amazon.com/dp/B0923XJR2X/?c ... _lig_dp_it
, https://www.amazon.com/dp/B087JKDVTF/?c ... _lig_dp_it
). You're now moving away from the "I need a light for a houseplant" and more into a "closet grower" type light system. There is an ongoing war between advocates of most of these models. I'm not in a position to say one is "trash" and another is "gold." The specs on most of them appear substantially similar, and I've never met someone who was disappointed with their purchase, regardless of the model (apart from very obvious knockoff models). The main difference appears to be cost. There is a wide variety of sizes and models. Cost is a little higher than the previous options, but so is light output. Most are dimmable, but will require more space.
Next is probably an HLG light (https://horticulturelightinggroup.com/c ... -600-rspec
). You're now moving away from the "closet grower" group and more into the "horticulture grower" group. But HLG offers kits to build your own, and has very good quality products. There is an associated increase in price tag.
Lastly, and while I put it on the higher end others might put it either right before or right after the Mars Hydro group, is Carnivero's Florawave lights (https://www.carnivero.com/collections/f ... row-lights
). The owner Drew used to work for Google and knows his way around lightwaves and lights. He used his knowledge to develop grow lights specifically for use on Carnivorous Plants, as he owns his own CP store and greenhouse. Whether the light output is really better than competitors, I don't know. But the website has an abundance of information for you to determine for yourself.
I've used most of the above type of lights at one point or another (not counting 20 years ago when you could only use CFs, crappy UFO LEDs and tube lights), although I don't have any personal experience with HLG or the Mars Hydro group. I now have a Florawave light and very much enjoy it. Sadly it doesn't have a dimming capability, and it might be a little too much light for my 4'x2' grow area. But overall my plants haven't complained.
