Bc blondes 800w cob

This light arrived today. 4 days after order. Initial inspection shows a very clean sturdy build. 22in square and 4 inches deep. Which is very dense and would be better spread out more imo. It comes with one power switch fot the inside 4 cobs 200w and another for tge outside 12 cobs 600w. Together 800w output. 3590 cd bin with mw drivers running at 1.4. I opened it up and confirmed the drivers but cannot find number on cob itself. Help on that? Here are some pictures of it hanging in the flower tent. Visually way brighter than my other led/lec combo

Is that the chinese made non chinese knock off light? That was a joke referencing their marketing. You wont find the type of cob on the cob. I thought they were supposed to be cxb3590?

I reread your post. Are you talking about Kelvin? On the site it looks like they are 3500k

they are supposed to be 3590 3500k, bin CD. I was just wondering if there was a way to check that physically on the cob somewhere, but didnt see anything.

Idk if there really is any way to check them other than using some high tech equipment lol.i got a stack of cd bins here and this is the only markings they have other than the cree stamp on the opposite corner.


Seems like all the newer chips have cree written in gold letters.
Sweet light though,cant wait to hear how it grows for ya.peace

There's no way to know bin, unfortunately. At least not that I know of.

damn, congrats I bet its bright!

airwalker16 is right no way to know forsure bin but markings can give you some kind of timeline as the marking and color has changed over the years.

it should be about 846 watts at the wall

It is bright. It probably wont make much difference on the plants at 40 days in there now but in 3 weeks i can start a new run under it and journal it. I think i need a light meter to figure out the best height and layout in my 4x5 tent considering how compact the light is. I am thinking stadium style with light 24-28" from center of canopy tops but need to check

Are you running the light on 110volt or 220 volt?

You can adjust the power supplies to output another 100 or so watts, (would draw about 940 after warmup on 110)
Just open the case, pop off the rubber grommets on the drivers and turn the adjuster to the right, it will only turn a bit but it will make a big difference.

Yes the chips are all cd bin, we want the best yields for our customers.

Let me know if you have other questions thanks.

Also if you can elevate your outside rows so your plant canopy becomes a bowl sort of, that way you capture all the light. This is how we do it in the test lab.

Actually I remember adjusting your power supplies up, so should be pulling about 940 , at 110.

What meter are you using to verify wattage? I use a kill a watt. Thanks

i dont currently have a kill a watt or lux meter. Can you post or pm me any of the lux data on that light?

Just to clarify wattage. Yes the chips are using about 800 but you also have to take driver loss and fans into consideration.

At stock settings you are at about 784 on the chips alone, then about 834 with driver loss, and another 20 or so for the fans

Which equals about 850, this is before the drivers are turned up by about 10%.

Turned up to max your at about 860 before driver loss, 915 with driver loss and another 20-25 for fans. It's a fucking behemoth, 4x5 is a great footprint for it

Hope this helps.

i didnt even know you were on this forum.

i am on 110v, any links to your test grows or light meter readings on a 4x4?

no shit! wish they had chimed in before to rep their company!

It's pretty cool that you can "dim" it by adjusting at the dial on the meanwell.......

It does not look like they are an advertiser, so they probably have limits on what they can post.

any ideas on what the same setup is doing @ 240v ?

i dont think the intake voltage would change anything significantly.

From what I've seen at 240v it draws about 100 less watts. So it's definitely worth it to run 240. I run all mine on 240.

I'll post a par map soon, the numbers are insane, but what I really like is grams and pounds, and the real world results are backing up all the specs. I love these things.

Here's a pic of a 4x4 table with the outside row elevated so you can see what I mean

So you're gonna put your pots on the elevated wood? Isn't it a flood and drain??
