A company called Sundopt makes lights on contract for several well known and regarded "budget" fixture companies. They have a US warehouse at least and maybe Canadian. 720 watt lights for less than $400.
Medicgrow has great lights for excellent prices.
Just saw the Mogobe octopus 300w light for $169 on Amazon.
Soooooo many others. Cocoforcannabis has great reviews of several less expensive models.
Seen a grower on here rock a Samaphon (spelling?) brand bar light next to a comparable MarsHydro, and it definitely held its own.
The Updayday thread is fun. Love the concept of their lights, and that they are a HID ballast company that pivoted their products to led when the writing was on the wall, but not sure the quality is quite there yet. If they can improve reliability, I think they could have one of the most compelling budget offerings.
Thanks for sharing some info on some of these other companies. I've never heard of any of them, except marshydro.
About the Sundopt company making lights for several "brands" of sellers, it wouldn't surprise me if all of the "budget" led brands were actually made by a very small/much smaller group of companies, and then they just choose a name (or a string of letters of or words) and have it silk-screened or printed on the fixture/board/etc. That's the case is many if not all industries. Eg: Alot of car manufacturer will sell you an oil filter with their "brand" and logo on it. But they do not make oil filters. They're made by one of the companies that does manufacture oil filters, and then they have them wrapped with their logo and charge more.
I think there's so many things that would need to be considered when trying to actually compare two or more "brands" of light or specific model of light, for sure. Just saying "Shmopyacktu" makes an 800W light for $300 doesn't really mean too much - but if it does a good job growing quality crops of whatever's in the garden, then that is perhaps the easiest, laymen;s terms...way to asses if it's worth it, I guess? It's "fair enough" at least.
Price, components (diodes, drivers, terminations/connectors, reflective material - if any, etc. etc.), features, certifications, warranty, lab reports, reputation/history of the company (and the light; how long has it been around, maybe), warranty coverage and length, customer service, and probably more, should probably be taken into account to properly "compare" things.
But with more and more well known, reputable companies making leds lights, and their prices getting better and better (I'm told), I don't know any reason someone would go with a "Gudbuynowpls" brand over say a growerschoice
other than price alone?
I think it's been addressed before (by multiple companies, and by led knowledgeable people here and elsewhere who know way more technical details than me) that sometimes the claims regarding diodes or output (for example) alone compared to the price is a red flag that highly suggests some level of...bullshit. I don't know from experience though, never bought anything from these companies.
