You won't regret it i'm sure

Lumatek's numbers and certificates are real, they follow strict standards and tests. But Mars numbers are highly inflated, and i doubt their certificates and quality checks. They can use quality components but if they are not assembled and checked properly, they won't be good. Not to mention they sometimes send wrong parts, for example a different driver brand than advertised.
I'm running Migro Aray lights now, but for my next bigger tent i'm definitely looking at Lumatek or OpticLED. Those 2 are my top options.
I had a Mars Hydro light once, and i will probably never buy it ever again. It came with a bent reflector, the light was running hot like a toaster and it smelled like burned electronics. Then i waited for a refund for 2 months going back and forth through e-mails. 0/10 i wouldn't recommend. Those who had a good experience with Mars are lucky. I read a lot of reviews and there are many bad experiences as well.
I would only buy Mars again if i was rich enough to afford gambling lol..
I understand your canopy issues. But in my country 1 x 600w is about the same price as 4 x 200w. Just find a good trusted shop with a good customer service who will honor your warranty, since Lumatek doesn't sell directly, only resellers.
