Something along the lines of a 600w -720w bar light.
There's 100s of them. With very varied price
Any reason you want to change ?

Want to start new grow in new place and want to try led. Never used led to flower before. Looking for a good light. Current grow is veg under 1000w mh and flowerd under 1000w hps Ushio which has been yielding good results

And that's an example of the top end of the market.
I'm not sure the difference in price is worth the fractional gain in efficiency
Edit (the cheaper light claims the higher efficiency, it's just hard to believe)

Grandmaster torch 850 has replicated the hps and mh spectrum and would fill up a 4x4 nicely. Might ease the transition a little. Super solid company.

Check out "migrow" youtube channel. He does tons of testing of the most popular lights on the market and has a wealth of knowledge in the lighting space. Covering old school lighting mh/hps and it's progression all the way to current tech. There is going to be a lot to take in. To help simplify what to focus on when comparing different led's and brands make sure to pay attention to the diodes being used and drivers more then the light manufacturer. Samsungs LM301 (b/H) are the most popular and decent choices, but there are others. I think the LM301's would be a good choice to use as a benchmark when comparing lights performance to cost. There is some nuance, but it's where I would start.

I would love to comment, but the last time I expressed my feelings on lights like the omega black I had my comment deleted. Can't remember exactly what I called it, but I'm sure it had something to do with "Pears, Oranges, and Sugar".
I'm definitely not going down that road again.

Just a heads up. If you are moving to LED from a HID setup you need to be able to keep your grow space warmer to compensate for the lack of IR given off LEDs compared to HIDs

Are you speaking from experience using them?
I'm sure you're allowed to call something a piece of shit , if you think it.

You pointed out the obvious yourself with the overstated claims " it's just hard to believe". So first thing I look at is the diodes being used. That will pretty much tell the story. We can look at the diodes data sheet and get a pretty good idea. However, there is no mention of what diodes they are using or spectrum. They are using terms like "Super Lumen Technology" and "pro par series". Truth be told I was out at "lumen". Lumen isn't typically used for measuring led grow lights. You may have heard "lumens is for humans" before? They claim it's a 720w grow light but the driver they use is 600w with a "super Lumen setting". "Lightest light released-weighs next to nothing". To me that means poor quality heatsinks. Heat is the enemy of electronics.
No doubt it will grow weed. How much better than a hps we can have no idea with the info given. Cheap lights with even cheaper drivers and heatsinks with vague/poor descriptions scream FIRE to me.

The 600w Lumatek Zeus Pro LED light is the same as a 1000W HPS bulb if not better than a 1000W HPS Bulb. But you won't need one of those for a 4x4 tent. The 465w Lumatek Zeus Pro is perfect for a 4x4 tent. If you buy a 600w lumatek zeus pro it will be too much light for a 4x4 tent. The 600w lumatek zeus pro is designed for a 5x5 tent and the 465w lumatek zeus pro is designed for a 4x4 tent.

I'm on my second run with a Phlizon FD6000 640w, it easily replaced a 600w MH/HPS light with a 42" parabolic reflector !
Their 800w is only $40 more

I'd still run the 600w at 75 or 80%, better coverage and uniformity, not sure if you can squeeze one into a 4x4 tho.

I currently run a Tomahawk 720 from HLG. It gets great even coverage throughout the 5 x 5 space and heat is not a problem. You can mount the driver remote if you would need. Best part. Great customer service. Did I mention made in the USA? Comes with a 5 year warranty. Hands down best light I have run. GL! Will not fit into a 4 x 4.
