So you don't have to search - I measured the PPFD of this light at 100 umol/m2/s at 100% at 4", about 75 umol at 6", and about 50 umol at 8" with a sharp drop off below that. Good for some low light plants where you can get close to the canopy, but for anything with varied canopy height where the light needs to penetrate, you may want to consider another option.

However, for the price, this is surprisingly well made. The base is solid and the telescoping height-adjusting rod sturdy. Timer and dimmer functions are spot on. The diffuser is a nice touch that adds to the look of the light.

I tried it on orchids, but the flower spikes prevent placing the light to provide much to the leaves. Not bright enough for succulents. I have one on a young calathea and another on a young nerve plant that were both recently split, with the light positioned close to the leaves, so we'll see what happens.

Great for un-yellowing sneakers

This high beam LCD Lite is super great. My boyfriend had a set & I was impressed. They “outshined” my set which were also LCD. It has a timer. Which I don’t use cuz it’s LCD, no heat lamp. It’s durable look & is
certainly a value for money.

Seeds have all popped and seems a gd light steams growing nice and straight 🙏🌱
