I have been growing outdoor and indoors for more than four decades a few years ago I decided to try LED to replace HID. Over the years I have tried three different Chinese LED manufacturers and they all defrauded me in exactly the same way. Do not do business with SHENZHEN LED STAR this company are liars and thieves. In fact all three Chinese companies I tried to do business with pulled the same stunt. The overcharged me to build custom lamps and then sent me a standard lamp. Their crappy lamp failed but not before burning my plants with UV because it had the wrong spectrum. Their excuse was they did not understand. So their excuse is they are so stupid they cant do business properly. So beware China is the Kingdom of Scammers.
Ohhhh..My friend now,I've to strongly disagree with you .... The kingdom of Scammers is my country.... Greece !--------------------------------------------------------------------------------------------------------------------------------------------------------------=> ( Was "Hellas" ,before many years ...Now the " light " has faded away => (H)"el" = light/bright & 'las'=stone ==>land of bright rock/white marble... -------------------------Anyway..................----------------------------------------------------------- ...You just can not judge ,a whole and massive industry ,just by your mishappens.... It's pretty absolute and unfair....... Kinda old-fashioned-way-of- thinking,maybe ,also..... ...... Yes ,it sucks big time & you're not the first,the only one or the last one that got the..... rotten apples ...... But ,there are also plenty of trustworthy professionals there,also.... One main thing ,when dealing with them ,is to let them know that any of their acts & deeds is going to have a large positive or negative impact for their bussiness.. One other thing,is that you 've to show/prove that you Know perfectly what you want & what 're u talkin' about.... Once they realise ,that is going to be , both hard & risky ,to trick you...They won't do it... ...... -------------------------------------Why you didn't order it ,to be made in a EU / US factory....? There's got to be a good reason ,there.... (Probably you would've gotten what you wanted...But also there,you'd have been ripped -off ,in a more civilised way ..aka "overpricing"....Western labour (our one ) costs pretty much,my dear brother....Eh ?--------------- So...Where is plenty money or even , where is lack of it ,thieves always await ....Meanin' ....EVERYWHERE ! ...)
