Nice looking area they have there!
I can tell YOU enjoy spending time in that space also.
I’d even drop that light a little more.
like 3(ish) inches... also look for more.. it can never hurt.. here’s a LED panel that I’m very fond of (I own THREE of this specific unit.)Dirt cheap and you can SELECT your spectrum compilation (to a degree)
Easy to Set up - Ultrathin & lightweight designed panel for easily hanging anywhere you want with hanging kit included; Hook and carabiners for convenient place and remove, free to change the position.

I actually have a fourth on the way.. i have other light panels too.. but when I found THESE (that link).. i’ve been buying them, solely, since.... the price is SOO good.
Those panels may be very good value for money. But I have some issues with buying these. Yes, they are cheap. But 1) they are blurple and 2) the efficiency or PAR values are not listed.
I looked into this a bit and it seems that with technology today, you should definitely go with white light full spectrum LEDs. These are very efficient blue LEDs coated with phosphorus to generate white light. This helps in many ways, including being able to see how your plant looks in semi-normal light.
Second, you really want to know how much light the light produces and how efficiently it does so. Forget lumen or lux completely. What matters is how much photosynthetically useful photons it uses. And the efficiency tells you how much watts it turns into how much PAR.
So say you want to root uttings in a 50 by 50cm area. You need about 400 micromoles of photons per second per square meter in that area. Since you have 0.25 of a square meter, you need a total PAR of 100 micromoles per second of photons. A good value for a cheap LED is 1.5 PAR/watt. So your light should only cost you about 67 watts of power. If you have a high end LED, you pay more for the LED, but the efficiency can go towards 2 PAR/watt. So you'd only need a 50 watt light. And in the long run you will save money on less electricity. If you have a larger area, you need a light that outputs more PAR. If your LED is both low wattage and low efficiency, it will produce a poor light level.
All this also tells you how much area you can cover and how high you should hang your light.
Of course if you just use a light to add a bit to the ambient natural background light, that all is a bit moot. But for most of us it is winter time with short days, so then you do depend on the LED for most of the day.
Since there are so many good and relatively cheap LED lights out there, it makes sense to buy at least a light that gives these numbers publicly.
