LED light confusion

[Highcountry]

I have a 20”x36”x60” grow tent. I am currently using an Wills best 600 watt grow light. My first grow was with Blueberry bag seed. The buds were quite airy, but powerful about 21 % based upon dispensary weed comparison. I am currently growing Aurora Indica which is three weeks old and growing quickly. Do I need a better light to grow firm buds? I would like to stay with LED, but it is so confusing looking at the lights at Amazon. What advice do you have?

DAZED AND CONFUSED,

I been there!!! I looked at at least 50 fixtures. Amazon is crazy with them!!
What I've learned is:
1. Watts from the wall is the number you use.
My Mars Hydros which I love have numbers that in no way represent wattage. I'm thinkin they're catalog numbers lol. A TWS 2000 & 2 TS 600s should be 3200w right? Nope- 507w together.
2. Get a light with a flowering footprint large enough. You can use more than one & overlap/extend the area covered.
3. The light to heat ratio. Cheap cheap will give less light & more heat.
Hope that helps & I'm sure that those who've taught me will have something to add.
Edit Oh- I forgot #1. ALWAYS get the best you can afford.

Is this what you're using?
You have approx 5 sq ft of area you're trying to illuminate.
Basic rule of thumb is 50 watts/sq ft when using older 'blurple' leds.
More efficient diodes like those used in QB's or light strips give the same amount of light at 30 watts/ sq ft.
So, you need 250 ACTUAL watts of blurples or 150 watts of QB or the like.
You'd need at least another one of the fixtures you have to get close to enough light. That's the primary reason you'll get airy flower-not enough basic resources for the plant.
