How are you planning on hanging it?
I don't know a lot about aroids but I think they are low light plants. Viparspectra's lowest power light is the P1000 and its pretty powerful compared to those purple lights you have. Probably 5x as powerful. But it's a square panel, it won't spread the light out along your shelf very well.
I would get a 4 pack of these and start by only using two:
Barrina Grow Light Bulb, 96W(4 x 24W, 600W Equivalent), Full Spectrum 2FT LED Grow Light, 2-Row V-Shape T8 Integrated LED Grow Light Strips, Plant Lights for Indoor Plants, 4-Pack https://www.amazon.com/dp/B07ZYPNG17/ref=cm_sw_r_apan_i_628FB8MR6T0BVPHJ5XD9?_encoding=UTF8&psc=1
Nope. I would do one of these lights per plant tbh, they're weak af.
Can I suggest full spectrum (white) grow lights? These pink ones make it impossible up see your plants and they make the room look like a club (or a grow op)
These would work well for this setup
This comment was very helpful! The tree was growing in a window before. And now it’s not getting any UVB. So I think your on to something with the “tune”. The lights are on a 12 hour cycle. And I don’t have a fan, I’ll look into what fans do.
These are the lights I use, I think there good. https://www.amazon.com/dp/B07ZYPNG17?ref=ppx_pop_mob_ap_share
Ditto this. I used 5000k, 1000-1500 lumen LED bulbs from the hardware store for years and have only had great results. The screw-in 'grow' bulbs you'll often see may offer a marginal improvement (I'm not convinced), but they're far more expensive per bulb. When you have a lot of fixtures, it'll add up fast.
Personally, I stay away from the red/blue/purple lights because I think they detract from the overall ambiance of the room. I'd also avoid any lights that draw their power over a USB port, they aren't going to be nearly bright enough.
I recently upgraded to these lights because I wanted something less intrusive in my space.
You could always just spend a little bit more to get some T8 LED's and hang all 4 above your plant. And then if you don't plan on continuing to grow, you can repurpose them as shop lights.
these are the ones I use. I also got some smart outlets that I connect to my echo dot and then I schedule light. It depends on the plant and how much light they need but I just put mine up in the windows and any plants that were already IN the windows are pretty much covered
These are what the partner bought last spring for my seed starting for my vegetable garden.
Okay so these are similar to the ones I have
And then I just put them in the windows like this. Then they act just like sunlight coming through. I also bought some smart outlets that I could connect to my echo dot to put them on a timer (or you could find similar ones that already have a timer but I find having the app to be more user friendly)
I had a quick look and I can't really see a difference? If I were to guess, I'd say it's probably just the colour emphasis/warmth of the lights (eg. some are whiter and some are yellower). Possibly the price reflects stock, sometimes the price goes up when stock is low.
Was there a reason you picked these lights? They look somewhat small particularly for the price, though you don't have many plants it sounds like so it may not be an issue. If you're open to hanging lights rather than ones on a stand, I currently use Barrina lights (also available on Amazon) and both I and my plants have been extremely happy with them. I've been running 14 feet of them for a couple years now and they're still going strong. I have them hung around the perimeter of the ceiling above wall/ shelves and they light my entire 90 square foot office / plant room. You can hang them with no drilling required - use those double-sided removable stickies meant for hanging picture hooks and just chain zip-ties to the height you want. You can see my setup here, if you're curious: https://www.reddit.com/r/houseplants/comments/y9g4sx/my_notools_noholes_hanging_grow_light_setup/
They're currently on sale on Amazon for CAD$70 plus an $11 coupon (so, $59) for four 2-foot long lights (8 feet of lights total). https://www.amazon.ca/Barrina-Equivalent-Spectrum-V-Shape-Integrated/dp/B07ZYPNG17/
If you can't/don't want to hang from the ceiling, you can always get L-shaped shelf brackets to mount on the wall and hang the lights from those. For eg: https://www.amazon.ca/AddGrace-Triangle-Brackets-Decoration-Supports/dp/B08G1G7RR3/
They are woefully weak. That "100 watts" in the answers is bogus. I have one, but I, too, use it only for just germinated seedlings.
Many kinds of lights will support growth, but unless they are specifically designed for growing and include at least the most essential red and blue (which common LED lamps do not), they are rather inefficient electrically.
You can identify actual grow lights by the maker presenting PPFD ratings and displaying a graphic of the spectrum. You will note that even though these satisfy one of those, they omit any PPFD information. That's because it would be an embarrassingly tiny number.
I will give you two that are very popular and for different growing configurations.
One is this from Barrina.
https://www.amazon.com/Barrina-Equivalent-Spectrum-V-Shape-Integrated/dp/B07ZYPNG17?th=1
You will find this on Amazon in 2 ft and 4 ft bar lengths and number of bars. Barrina is gaining a good reputation.
This next one is one someone asked about, and I was impressed enough that I bought one to test and then bought more. I found their PPFD numbers to be accurate, and it seems a well-made product.
https://www.amazon.com/Barrina-Equivalent-Spectrum-V-Shape-Integrated/dp/B07ZYPNG17?th=1
I'm not recommending this next one yet, because I just received one I ordered to test. It's PPFD numbers seem very high for the low price, but grow lights is a very dynamic market. I should get to test it today and report.

I did a piece for my blog about evaluating lights for specific situations that will tell you how to do it and explain some of the issues.

It's absolutely possible to use grow lights in the absence of natural light. Check my thai con post on my profile. 100% artificial light, no fancy hardware.
Currently I'm using Barrina Grow Lights mounted in a shelving unit for all my plants. Although before I upgraded, I literally just used regular high-lumen, daylight light bulbs in ikea lamps as my grow lights with amazing success (again, check the thai con).
Is the light overhead or off to the side? If it's off to the side that's your first problem.
Next, forget these blurple lights. Fill spectrum is much easier on the eyes and you can actually see your plants. I would suggest Barrina T8s, or Sansi 36W or 70W bulbs (you can screw them into lamps, pendant cords, clamp lamps, get creative . Which one is most ideal for you totally depends how far away from the plants you'll position the light.
