Luckily my supplier is in China so Kingbrite will get theirs first lol. I'll find out in a bit if Kingbrite is gonna have them in stock today, because I was chatting with Jerry yesterday and he said they might be getting some CXB's today.
wait today as in yesterday in china or as in today in chine tmrw here ; o lol trollin. hopefully your right. If your not then I dont doubt itd be too long. Who really know, till it happens.

I know it's Friday in China and China has a 16 hour difference from me I'm on the west coast. Jerry should be on Trademanager within an hour or two.

This is why I grabbed four cxb3070's while I'm waiting... Until the 3590's are in my greedy little paws I'm not counting on them. LOL

Anyone placing an order with Kingbrite? I'm interested in purchasing some CXB3590's but I don't want to pay $60 shipping on 8 COB's. If someone is ordering and would like to split shipping please PM me.

He can ship with China post for 15 bucks but the wait will be significantly longer than dhl, dhl was within 3 days from China. You're talking 3-4 weeks with the post.

3-4 weeks is right. Damn China post :finger:

I also went with the CXB3070s because of shipping issues with 3590.

Clearly I am a little fish in this pond, sounds like I will be waiting for some cxb3590s to fall through the cracks lol

Not going to lie, pretty cool knowing a lot are going to members on here lol at least it sounds like it

I have been thinking of making a CXB light as well
I understand that running them on low current will be very efficient although high upfront cost. I know the plants will look great under some 90CRI bright white LED, however i am still thinking if that increase in efficiency offsets the following
1) These are white light and do not target the specific wavelengths for photosynthesis unlike those 7-11 band lights
2) Lights with multiple small LED's can have focused light with optics.

Look at the spectrum given off by the "all white light" cxa/b3070s... it's probably about as close as your gonna get to hitting the RIGHT peaks in the RIGHT amount using quality parts, delivering some serious amounts of light...in one of the most efficient ways, optics have losses and these cobs typically don't need them unless you're lighting a ~4x4 space or are keeping the light raised 24+" above the canopy, which means no losses.

Those 7-11, 14 band wavelength panels are usually junk, and are stuck in the dinosaur Era of LEDs where the big SALES PITCH was their way of being efficient was targeting the important nanometers, where the reason they are a better light source than others- is they are typically more efficient, regardless of targeting a wavelength or not.

Be aware if you target to much of one wavelength and not another. You will bleach your plants. Good luck and hopefully you understand that it's worth the investment

Hi guys. Do you know if Supra has made a efficiency chart (the ones he makes with diss wattage, L/w and efficiency etc in the spreadsheet) for the cxB 3070? any one have any links to these, ive searched and searched, maybe he hasnt made one yet?

Thanks in advance, this forum and its members are great.

I look at it in terms of $/PAR W and ask myself how much I am willing to pay. I think $1.50-$2/PAR W is reasonable compromise, $4/PAR if you are experimenting, demonstrating or money is no object. $5/PAR W for vegging since a little goes a long way.

what is LER for cxb2530's? How do you calc efficiency again?

Trying to figure for these @ 800ma

edit: free shipping ;-)
