About 1 year ago I got into LED lighting. I bought 2 boards. 1 SF-4000 branded as a Spider Farmer light ordered from amazon for $628 and change with sales tax. I also ordered a 660w qb from alibaba. The alibaba board arrived 4 days before the amazon board even with prime shipping. Which board do you think I'm having problems with only 1 year later? Today I inspected my 2 new 660w boards I recently ordered from alibaba. 4th light purchase from the same vendor. I verified the mean well drivers were authentic by running the serial numbers. As I was comparing the drivers and construction between the 660w alibaba boards and the 450w spider farmer branded SF-4000. I took the photos I wanted to take, and I was in the process of hanging the board. Then I discovered this on my UL listed SF-4000 bought in the good 'ol USA:
The fucking board is literally burning up. I will never again recommend spider farmer. This thing is a fucking fire hazard. I've ran 1000w HID's and 600w HID's for years without a single problem. I use a spider farmer board for under 1 year and the mother fucker is literally burning up at the PCB. Wanna see something else I discovered?
I noticed the heat sink was visibly much larger on my 660w alibaba board than the spider farmer sf-4000. I busted out my micrometer to check the thickness. Here are the results:
Alibaba 660w qb:
Spider farmer sf-4000:
The alibaba 660w qb is equipped with a heat sink that is nearly twice the thickness of the spider farmer branded sf-4000. I'm so fucking infuriated right now I can't even see straight. Let this be a lesson to anyone who is operating under the false idea that buying on amazon or from a US vendor is safer or than purchasing on alibaba. Just seriously what in the flying fuck man? Fuck spider farmer in their spider fucking asshole. Diodes going out? I can deal with that. A PCB literally burning up is un-mother-fucking acceptable. Sorry for my tirade. Avoid spider farmer at all costs.
