Vanq LED chips

Hey guys,

Just wondering what everyone thought of Vanq LED Multichips? They have 1-500w chips that can be fully customized.

Anyone have any opinion on the led chips themselves? I plan on doing a DIY LED light and was hoping to use a few of these chips.


Also what spectrums should i use for my chip to create a well balanced full spec light?

Those look exactly the same as the LEDs that are in my panel. I was planning on building a panel my self out of the multi chips because its alot easier to wire all that shit up.

But instead i bought a couple panels from growevolution.com When i worked out all the money, time, and frustration i was gonna put in doing a DIY was about the same as if i ordered one from them so i said fuck it and got 3 panels.


I wouldnt doubt if he ordered his multichips off that site.



on the other side, ive heard Vanq are lacking on the customer service end. Orders just show up one day without being givin tracking info or even knowledge that it was shipped out, they take long because theyre a custom shop and dont have a problem telling you its going to take longer. Which isnt anything major in the custom fabricating business, but can get annoying for growers.

As for spectrum, id look up any reputable LED manufacturer and see what they use and copy it.

why those multichips at all? are there any superb Reviews?
looking at their budboss, 600$ for 340W...id just think, going all White Arrays, maybe mixed in some red Arrays u would get 500W including Drivers for 220$ and had left 380$ (or 450$ if u wanted 340W) for a heatsink, fans, screws, wire, drill and to make up for ur frustation (if you feel that way...for me it was fun)

Its not like it wouldnt be fun but possibilities of shorts (especially with the static of winter) and not working products and dealing with ebay sellers from china just seemed like too much. It wouldnt be difficult, but it would take time and investment and still cost about 2/3 of the money. So i said fuck it and went with them. My budboss cost 500 a piece and i bought 3 so they gave me a "bulk" discount on top of the discount code i got before.

Plus, having a good body/case is worth a few extra bucks.

Ive been confused about all the fuss over white leds. I thought that was the point of LEDs to eliminate the bullshit spectrums that the plant doesnt really use and hammer on those spectrums it does.

I can understand using some whites but mostly whites??? Just kinda undoes the whole LED point in my mind. Area 51 knows what theyre doin but... idk i just cant get over that you can buy a 600w mh with just as good spectrum as 600ws of white LEDs but the area 51 has some reds mixed in. I might just need to do more reading into it.

What do you mean with static of winter? e.g. you wear Nylon Pants and get electric Shocks when you touch Metall or what do you mean? either wear different clothes or touch something like your heater with the full Hand to avoid that ;-)
but what does this have to do with the light? (if this is actually what you meant?

I bought so much in China (having fun building other electronical stuff)...never had Quality issues with them but one thing Comes to my mind: a freaking Cree XML-U2 (like 4 Emitters in one, looked like art) yet it burned out. Sent photos, next day chinaman wired my Money back.

About the good Body/case...I dont think my DIY Looks too shabby, and maybe its even more safe, since i seperated the light from the drivers and with that from the mains...gives me a better feeling working around it...
And you can do funny stuff like attaching fans to the light for the plans as i did or other funny stuff that comes into mind.
Maybe ill add a microcontroller for temperature and fanspeed controll or something else.


About the whites: I think mainly the reason is the efficiency of white leds compared to others. And its been like proven plants even suck in green and yellow and whats not...
so i think its like: more efficiency + plants ultilize the other wavelengths too = 1 White puts out more usuable stuff as the same Wattage red = Profit, and maybe add some extra red

Yeah all my furniture causes it. No matter what im wearing. So if im sitting at the table and get up and forget to ground myself i wouldnt want to short anything out. Glad i built my computer a few months ago.

And ive always had good business with china stuff off ebay i just wouldnt want to invest all that money and possible fuck it up. Plus the 5 year warranty from these things is awesome. Anything goes wrong i can get it all replaced for free. Might have to pay for shipping but im not sure. Like htg does. Love some good customer service.


I was mapping out my panel i wanted to build but it woulda been tough for me with my limited electrical knowledge. If i knew a little more id take on the task.

I don't mean to get this off subject, but florescent fixtures make great cheap housings. You can find them free with bad ballast and they come 2',4', and 8'. With a jigsaw you can cut holes for fans and leds. The snap on cover makes access easy. With 3 or 4 4' fixtures you can saturate a 4'x4' tray. I bought an expensive light and built a single housing out of 4 8' fixtures. Fans are set-up as a pull thru system. 3 sucking air in 2 on other side pulling out. I do wish I would have done 3 4' fixtures daisy chained together. This was a magnum plus 2.

It is over a perpetual garden covering a 4'x4' tray with 330 watts. The light sits around 8" off the canopy of 12 to 16 plants in 3 g. bags. Every 2 weeks 4 go in and 4 come out. My set-up is now hitting 1 GPW. I have been averaging an ounce + a plant. Just cut down four more and I may have hit 6 ounces. To clarify, my flower room is about 4'x 7' of flowering area. There is a min. of 18 plants covered by 2 330 true watts panels. My other is the magnum plus. So I take my total of 660 watts and divide by 18 to get 1.33 ounces per plant to be 1 gpw in soil. I have started my first DWC plant.

Wow, that looks great! I just started researching to try and do a DiY LED setup myself. Mainly for suplimental lighting.

What LEDs and drivers are you using? Do you have a journal?
You will love DWC BTW . I started in soil, moved to dwc and now using a 2 site undercurrent.
Good luck! Keep water temps cold and get a good meter!
First time poster here. Sorry for the hijack

Nice! ive got 610w of leds and hope to get the same gpw

I had no problem with VanQ or the products I bought from them. Their chips are not the most efficient (your typical Chinese stuff), but whose are?

I have a few of their test reports if you're interested in the efficiency of their products.

I'd simply upload the PDF if I knew how/it was allowed, I realize the way I posted these are sort of a hassle. Then again, I don't imagine too too many people are interested in this information. I believe you can calculate efficiency using the Fe values measured in Watts divided by the "lamp" input power "P." I've seen their multichips sell on eBay for pretty scandalous prices. I've actually contemplated pulling the trigger a few times despite the fact that I have no use for more light. XD I realize people are trending towards the best of the best, but I have no real problem with my Chinese lights. My plants and LED's are fine and am about to finish my second harvest, so they seem to be holding up alright. Fingers crossed it stays that way. If you're interested in a BUDGET indoor garden I believe these guys will take good care of you.







Hope this helps, guys. Take care.

Hi all,

First time poster.

I have been reading plenty and slowly putting together my ideal light. I bought the Vanq as a filler led. It supposedly had good peaks with an all round spectrum at low power in other areas.

I attached the latest advertised Vanq full spectrum Led company provided spectrum analysis which they advertise to be 45mil Bridgelux with phosphor. I tested the leds using a spectrometer to find the dominant peak is at 610nm with a 575 - 640nm range. There is quite a lot more green then advertised which I believe is wasted energy. The graphs drops off heavily at 660nm and would no way consider these full spectrum as the upper band in the reds is just not there. There is a peak at at 460nm which spreads up to 500nm which is nice. I bought quite a few of these based on their information they provided and can say I am utterly disappointed in the actual spectrum when tested and I believe they are selling a very inferior product to what they claim. In the last two weeks of flower I have put one in to use as supplementary lighting to see how it performs. It is with other leds which fill the gap in the 660nm area. Not too far away I also put a 660 nm similar wattage in to compare as supplementary light. They are both in exact same environmental conditions. The 100 watt 42 mil epiled based 660nm has shown to be far superior with incredible growth. There was growth with Vanq but no where near the same calibre. I am actually going to return the Vanq leds as I believe they are lying about their product. Luckily I used Paypal and have evidence to support my findings. At worst I lose the delivery fee. If any one is interested I can provide links to test results.

Just letting potential buyers know to beware.

Really good info..thanks. Nice to see chips actually getting tested finally

The 660nm sounds interesting. Any link to one for sale?

I bought mine on Aliexpress. I would not deal with the seller again. I did quite a large order and found they were trying to scam me passing off blue smaller leds as 45mil. The silly thing was they provided both sizes in different wattage leds. It was so obvious. Anyway they ended up giving me some money back. All the leds tested good with the spectrometer being true to the wavelength.

I have been mainly using these E27 fanless leds (see link) and was quite happy with them until recently when I tested the power draw and found them to be only 12 watts. That's a long shot from the 50 watts advertised. I would have at least expected 25 watts actual output.
http://www.aliexpress.com/item/54W-E27-85-265V-High-power-12red-6Blue-LED-Grow-light-for-flowering-plant-and-hydroponics/1049231950.html

I can say they do perform well though. From 550 watts of these configured to my color customization. I was getting up to two pnds using aeroponics. Not a bad return at all. Adding that higher power 660nm though seem to take it to an all new level so I will keep testing and find my ideal light.

Here is a link to a picture of the actual chip I am using but in a 100 watt module.
