Keep in mind thats not profit, thats gross. The design has been accepted and is waiting on parts to come in to be produced. The tech is better than HLG which is why it will sell. Im undercutting a large company by having no overhead. So I can create things at a cost that they can not. If the...

I did what I said I would do. I designed a light that pushes a minimum of 2.85 umol/W. What the means is that there will be a light on the market that is 600W that really is a 1:1 replacement for a DE HPS. All the details are on IndieGoGo. Please let me know what you all think. If I can get the...

Ive moved on to making my own lighting since quality is not possible to find. Im sticking with the LM301B for now. No other cheap way to get to 2.7-3.0umol/J from what Ive seen.

If you want to build the light you should go with Randomblame's idea. If not I would go with a used 1000W HPS (not a DEHPS) with a wide reflector. Cheaper till you can save up a bit more cash.

LED has so much misinformation you will get 100 different answers on whats best. We would need a budget to give a good answer. For HID it depends on what you want to do, if its Veg then get a 600MH if its flower then a 1000W HPS. Buy used components and new bulbs.

Neat then that should cover a 5x5 pretty easy.

You already have the QB288 V2 that gets there. Im talking something for about $800

Again, its over priced. Here is the same spectrum. Here is the same but from alibaba. Here is what they are offering for $1200-1600. You would think they would have their umole/J consistent. Unless they're different some how?

Anything over 1K is over priced everytime imo.

What is your normal budget for lights? Does it depend on the quality or the wattage? Maybe both? For me its always been something under a grand that preforms well, but how about everyone else?

I like the design and theres not a lot of overhead on the boards, it would cost me $88 in LEDs without the board or manufacturing costs. So if I can get the boards for 100 each and get free shipping, maybe get the heat sinks, get the driver for 100 somewhere else... Should be looking at $400-500...

Nice I was quoted $800 to get three boards shipped with a HLG-600 with all the bells and whistles. Maybe If I buy separate Ill get a better deal.

I was looking at those, did you get a kit or buy only the boards then get everything separate? They want $600 for two boards and all the hardware.

"This was a special place in 2011 and beyond" Right? I only rolled up in 2015... People still on here talking about blurple beating HPS all day...smh I guess you have to justify a bad purchase to yourself.

Ill be following this. Was just looking at the company and it seems like they are legit, be its more expensive than people should have to pay. If I end up making my own boards Ill be following a similar design but more diodes to run more efficiently. you sure this isnt the 800 or is this the...

My votes with DIY quantum boards. Cheaper than buying a unit. They make the same one the HLG 550 V2 over on Alibaba or their 800Plus or standard 800 boards. I requested a third board and they stated it would be a bit more, but that would make it a 590W board that was at 2.8 umoles/J. If they...

Has me drooling lol

I know I cross referenced them, its a typo. Point is its a great option and depending on the cost to add a third board to my 4x4 it may be the cheapest and most efficient option as well. That would bring it up to 2.8μmoles/joule for about $600-620 is my estimation. I could redo my room for 3.7K...

Maybe I missed it but why are people not looking at the 800 board? 600W at about 2.7μmoles/joule for 2 boards and its $514. (the site has a typo but its supposed to be the HLG-600)...
