Hi No3odiesShad0w. The usb microscope I have cost $25 and has been a really useful fun toy. highly recommended.
Regarding lights, I had one Orange Bubba under the SF 1000 and it is doing a nice job and at the other side of the tent waqs the one under Best VA. Very slight difference in grow height and bud appearance so it's pretty much the same effectivenessas the Best VA 600's (which have 10 W diodes and were purchased for their intensity). That plant under the SF is ready for harvest today, so I think it i only 2 days behind what the other one was, and now that the buds are ripe I dont think I could tell the difference. The SF use a lot less power. In my other tent I have an MH TS3000, which is freaking awesome with it's depth of penetration. According to my PAR meter, I wont be able to run it at full power ever in my 5 ft high tent so it's somewhat overpowered. I also have another SF1000 in my little veg tent and it did a great job vegging a plant for a close friend. I wouldnt buy any more blurples myself, and am a fan of Mars Hydro and Spider Farmer. I will say that regarding the par maps the mfrs provide, the Spider Farmer was around 15% lower. I thought the SF1000 (which wont have a lot of penetration) might have inferior growth comparitively but it is not discernable to me. The spider farmer growth is quite nice if you look at the plant to far left in the photos. The Mars Hydro SF3000 PAR measurements indicate it has a slightly higher output than the mfrs ratings. I was just impressed by my blurples but will not buy again. This grow has convinced me to keep them until I find a great deal on a Mars Hydro TSw2000 for the 2 by 4 by 6 ft tent. there is so much second hand grow gear that i expect soon to find one cheap. None of the SF or MH seem to make colas as long as the HID 600W, but they both burn so much less (100 vs 160W) energy, which turns into heat that it allows me to run my fan at a lot lower speed because it generates so little heat. hope that helps. If I had the choice I would pick MH over the SF, but not by much.
