$229 for 800w LED.....how bad can it be?

[driver77]

While in search of an inexpensive led for a 4x4 tent...I found this *link removed by moderator* first thing is in description it says 800w but dig deeper and it's only 680w. Money is tight so it will definitely give the most bang for buck. Even claims samsung 301 series chips.
But it's almost scary cheap.
Anyone have any experience with this company?
Is 3000/5000 660 better than 4000 660 for diodes?
would uv supplement be required?

sounds very skeptical for using those chips,they are exspensive man....sounds dodge but who knows!

I pulled the trigger....if it's total garbage I'll send it back. If it's even half way decent it will be a great deal.

For a little more you can get some kind of remote control. Fascinating

There's a lot of very similar looking, priced, and specced lights on Aliexpress but all of them seem to use LM281 series instead of LM301.

I wish the included more details on capabilities of the remote. They are pretty vague about everything lol

I bought a led from Shenzhen Kingbright Electronics Co. back in 2019 and its a great light, still working and ill probably get a few more since they are still killing it.

Thats what pushed me to pull the trigger. No way I find a better deal with LM301's. Won't get here till the 16th, so I'll do a report back after.

The fake diodes I ended up with stayed lit for a moment and dimmed slowly after power down. If you've got a verified real Samsung light to compare to, I'd get it and compare them.

That's wild. Have you found any info on this anywhere.. the fake diodes?

You will need a par meter to test that light. 3 years warranty plus 30 days money back guarantee. If the numbers are good and it lasts at least 2 years that's a great deal for $250.

if it is samsung chip, pls pay more attention to the authenticity. it is almost 0.42usd/w. it is very skeptical.

How does one go about finding that out? Just by price or should they have some sort of certificate?

The price is one point. But there are a lot of versions like 301B, 301D, 2835, etc. Most of the suppliers use 301B to keep the light efficient. Some use 301D or less efficient Samsung chips. According to our experience, the real Samsung chip price would not be lower than 0.5 USD/W regardless of the different versions.

One of the pics says 23029 lumen. I'll believe that instead of the 2.9umol/j.


One nice thing about the design is the two drivers. Makes more sense to run two 300w drivers than one 600w, imo.

UPDATE!!

 

[driver77]

So the light arrived, a day late.....but...WOW! Draws from 60w to 830w with dimmer. I have a couple Bestva 2000 and at 24" they where around 400 to 600 par at best on my phone app par meter, which is kinda good for just a frame of reference not actual par. This thing was 500 to 700 with highs of 800 at 30" with MUCH better coverage area.

I can only say I ordered another immediately!

This came with it...
