Whatcha planning to do with them. General grow or a flowering board.
I'm starting a new journal this week using a 2x RedSpec flowering boards at 3000k and you're invited to come check them out.

I would actually go for the 3rd option and do a strip light.
Same PPFD but more even coverage.

So, budget is around a grand?
Couple 600-watt HIDs with "sealed" (air-cooled) reflectors CO₂ monitor/regulator/tank, dinner for two at a halfway decent restaurant.

We offer a very comparable grow light to the HLG 550 (480 watts). Top bin samsung and Osram diodes at a much more affordable price. As John Wick mentioned, he is running two of our 250w Red Spec Kits in a new journal soon.
We are running a great special for fall on our 250w and 480w kits. You can also take advantage of the 420MAG 10% off. Here is an example picture of a customers set-up. All feedback as been very positive!
We also work with customers on custom builds! This light is pumping 770 watts and PPFD of over a 1,000 at 24" and well over 600 on the corners!

I think you are choosing like between climbing Mount Everest or K2. Both choices are going put you up pretty high. The other analogy I like is its like going 800mph or 810mph...whichever you choose, you're bean is gonna blow off when you stick your head out the window. I got me a off brand 2x4 dimmable red spec flowering QB for about a third of the cost of 1 of those Timbers. It's all about your thumb bro, you aren't going to make the wrong choice here no matter what you choose. Although you're bank account might disagree....

First off, thanks for all the feedback! The light will be used for the entire grow in a 3'x5'x6.5' tent. I'm thinking I'll go with the off brand quantum kit of a pair of 250w rspec. Would I be better off getting one in 3500k and one in 3000k to start em off veging under the 3500 or is there really that much difference in the 2 spectrums? I want the best spectrum for flowering when it comes down to it. So I guess 2 3000k or mix them up?

Maybe see if the guys at Budget LED can fab you up a custom pair with both 3000k and 3500k.
Or 4000k.
Personally I prefer to have a slightly higher blue spectrum than most of these white lights put out.
I plan to have a bar of lights that I can replace with blue spectrum for the veg stage then change it out for flower.
Blue spectrum in veg is important IMO.

As Nunyabiz mentioned, we can customize based on the customers request. The Full Spec & Red Spec Boards can be run together. You can also mix spectrums. We build every kit to order. For your purpose, the 3500k mixed with the full spec would be a solid option. You get the Deep Red for flowering plus you get the added bonus of the 3500k plus UV.
If you wanted to stick with one board though, the 3000k / 3500k mix per kit would give you the balance you are looking for. Whichever way you wanted to go though, you would be getting a high quality grow light.
btw, Nunyabiz, love the name!

I plan on buying 2 kits for my tent. I think maybe I'll just buy one kit at 3000 and the other at 3500. Make for a good experiment if nothing else.
BudgetLED you have 2 different kits on your site. One is the series 2 full spec kit which only comes in 3000k .......
The other is the series 2 rspec which comes in both 3000 and 3500k...........
Should I just get 2 of the rspec boards; one in 3000k and one in 3500k or would i be better with one rspec board at 3500 and one full spec at 3000k.... ?
Please forgive my ignorance on the differences. The uv is what has me on the fence as there seems to mixed reviews on it's importance in the grow room. Is it a benefit worth buying over a light that doesn't have it or is it something only a science laboratory could identify in the final product?
Thanks for your patience!

Thanks for taking a hard look at us. Regarding our UV 385nm - studies have shown that 385nm promotes the build up of phenolic compounds, and also improves antioxidant activity of plant extracts. UV has also shown in some studies to increase THC levels in Cannabis.
The full spec currently is only offered in 3000k because of the added 450nm diodes.
I believe either option would give you great results. Mixing the two boards will give you the optimal results you are seeking - two Full spec boards and two Red Spec boards in 3500k. It would be a great full cycle set-up.
If you want two different boards per kit. Please specify it on your order so we built to your requirements.

Lots of good advice here!
In a 3'x5' grow tent I'd personally go with a light that is at least 4' long that gives even coverage and not a lot of heat!
You really want to have good control over your PAR values by the time you get to flower!
Also ... make sure you understand the spectrum before you buy a light!!!
Two Mars Hydro SP 250s are a lot of bang for your buck. I wonder what BudgetLED's equivalent is ...

Thanks for the feedback! Both of those lights are rated for a 2'x4' flower footprint from my research. The only difference would be how i put them in my 3x5 tent. || vs = As to understanding spectrum BEFORE I buy a light, That is the process I'm going through here in question period.

Question for you.
Do you have any plans in the future of creating any strip lights?
Something similar to a Flouence Bioengineering Spydr configuration?
And or even make a series of LED strips 2 feet long with various spectrums as a DIY light where you can buy however many strips you need to cover your canopy.
And have numerous configurations so we can pick and choose the exact spectrum we want.
If you can do that using all top quality diodes and sell all the parts such as drivers and heat sinks then you wouldn't be able to keep up with demand.

Yes we do and have a design in the works. It may be sometime until we release it. The frame design is the main hold up. Making them more affordable but also look nice.
If you have suggestions for strips you would be interested in, we are all ears. We do have some strip designs but our biggest hold up is diode selection and spectrum offering. We need the QTY to produce at a reasonable price.
We currently do sell drivers, we will begin listing them on our site soon. We have been selling them through DM, mainly.

The best frame I've seen is 1x1" T Slot aluminum.
Strong, lite and easy.
Heat sinks connect right to it with T Nuts anywhere with no drilling.
Plain old aluminum L channel works well also but it needs to be drilled.
A strip I would like to see is 24" long, 100 diodes, 94 of them 4000k Samsung LM301B, 4 Cree XP-G3 photo red, and 2 IR or UV.
I have 2 lights that I am working on right now that are going to be 2x2 square with 8 strips.
I am going to be dimming these down by about 40% because at full power they would be way too much light, something like 1700 PPFD, I want to dim them down to about 900 to 1000 PPFD which should get around 2.9+ Umols/j
But if I ever move and have a larger growing space i can easily just spread the same 8 strips out and crank them up to full power to get the same 1000PPFD in a much larger space all with the same light.
My efficiency would drop from close to 3 umols/j down to about 2.7 umols/j but that's it.
