40w led bulb

[Buckbotany]

I came across this 40w led bulb for $20 and was wondering if it would be a good bulb to use for veg in addition to my Mars hydro 300w
It's bright as hell, 5000k, 4800 lumens
Anyone used these before?

40w for $20 is not bad at all. What’s the k rating?

Pop that big dome off you will get a more focused light. More on the plant less on the walls.

Should be as effective as any of the screw in types, which are suprisingly effective, considering the cost...might even be a couple rungs up the ladder on overall quality.
