Pretty cool cheap LEDS from aliexpress

Anyone see these yet? They're only like 30 dollars Canadian with E-packet on Aliexpress. Figured they might be a neat additional/supplemental/veg light for the price.

The first one is supposedly 100 watts while the board style one with the 281b+ diodes is 65 watts. Seems kinda cool. I'm close to ordering one just for the hell of it.

Also, has anyone seen this before? The middle has an entire 3 rows of just UV and IR. Never seen that before! 400 watts for 550 Canadian or 600 watts for 800 Canadian. Free shipping. Supposedly lm301b also. Not sure if I'd ever buy it, but it would be interesting experimenting with that much UV and IR.

Just found this on aliexpress. If the par map is correct, thats a decent little 40 dollar canadian / 32 USD little fixture. Kinda neat! The upgraded vers (pic 3) is 60 dollars canadian / 48 USD.

Another cool light. 300 watts for 200 dollars Canadian.

If anyone needs links, I can supply. Sounds black marketish doesnt it.

281b diodes are as somewhat junkie, about 70% output per watt compared the high spec Samsungs. You can get 288qb boards from Alibaba for 10$ for these. And in AliExpress I wouldn't trust the seller. I'd pass
