So I want to make another light, would you recommend the first or second bulb, or if you have a better recommendation,I am all ears!
I am interested in the sunlight light, but have seen very little info on those.
Why are you looking at these bulbs instead of dedicated cannabis lighting? If doing diy there are many better options. If not and wanting a decent light, you should be looking elsewhere.

where would you recommend?
Start with this. You have a lot of reading to do.
Basically there are 3 technologies: MH/HPS, LEC or CMH, LED. Of the LED’s there are good ones and not so good ones. Pretty much everything sold on Amazon falls into the ‘not so good’ category, with a few exceptions.
There are a few companies doing really good lighting: Horticulture Lighting Group, CHILled Logic, Fluence, Spyder Farmer etc. HLG is the top of the bunch and have a really good line of top quality fixtures. They ain’t cheap. But you can’t grow cannabis with cheap light (sunlight excluded).
Remember that light is the engine that drives all processes. Without sufficient light, nutrient uptake is reduced, growth is slower, node spacing is larger and flower is loose and airy with no weight. Plant life processes are deficient and issues can develop as a result. Everything depends on good light.

That my main issue, I can not afford a great or even really good prebuilt light. I was really hoping I could make one, but I have only found lights pre made, not bulbs.( at least high quality) do you know of any bulbs I could use, that will produce quality plants,or is it just spend the cash on a pre made?
I was really trying to stick with led lights, due to my limited space.
Read the thread I put up. I built my own light. It is comparable to the offerings from HLG. @dbrn32 is our light expert and usually helpful should you decide to do diy.
I built 3 fixtures using Bridgelux EB strips: basically high end LED’s on a long narrow printed circuit board that you tape to a heatsink and shove a wire in the connector. Mine has 10 ea 24 watt (peak) 3,000K 80 CRI (Color Rendering Index) per fixture and each one cost me around $200.
That said; I can (and have) produce 2 pounds from 3 plants under those lights. And without killing my electric bill. So that’s the other thing to remember: the first month after installing my lights my electric bill went down $60. So I literally have saved $1,500 on my utility bill.

I am going through the thread, but it’s like 8k posts long, taking a little while to read it all. I really appreciate the info though!!! Thank you.

@Jstar I wanted to add to this. I’m on my 4th grow. So not really a beginner, but on my 3rd grow I harvested pound and a half off 3 plants. I was able to do this as a direct result of the lights I use, not as a result of being a experienced grower. @Myfriendis410 was also instrumental in achieving this by giving me good advice. I’m posting this so hopefully others can understand that lights will make a difference. Especially when you can only grow a few plants at a time.

@Myfriendis410 so you have a light simulator to the one in the video close to the end of the tagged post? I would love to build that light!

@dbrn32 2x4 tent and 1 Aeroponic build 1x3.

You want to build lights for both, or start with one and see how that goes?
I would love to build a light for both, but will probably be limited monetary wise to start with 1.

1x3 would obviously be cheaper. Would you be able to come up with some 2’ pieces of aluminum for heatsink, or is that something you would need to buy? Would you want dimming?
No dimming needed, at least for the first build. I am sure I can find some aluminum. I could buy that if needed, I have some to spend,more if I return the blurple lights I bought.

@Bulldognuts what light do you use?

With @dbrn32’s help I built three of these: I went the diy route because of ready access to aluminum. This cut costs a bunch.
