Light Output ... NO -vs- VHO ... 4 Foot Fluorescent

Like the previous video comparing brightness of 96-inch (8 foot) lights,
This is a comparison of brightness between 48-inch (4 foot) lights.
But this time we will use a few different types:
* Normal Output, Low Power Factor (NO-LPF) .. 48"
* Normal Output, High Power Factor (NO-LPF) .. 48"
* High Output (HO) .. 96" {yeah i know not the best comaprison}
* Very High Output (VHO) .. 48"
...I even throw in a quick view of a F32T8

Notes:
* All the lights have standard electro-magnetic rapid start ballasts
* (except the T8 & that OD-NO one, both have electronic)
* {For those who are wondering OD-NO stands for OverDrive Normal Output, it is a way of rewireing lights for extra brightness}
* I couldn't help laughing at the way my computer says some of the words here :)

My plan is to use NO, HO and VHO four footers in my office... since I'm lazy, I'll probably just set them down on my floor. lol

[XmasLightsGuy]

Should make for an awesome bright office...even with just the VHO's.

And LOL nothing wrong with just sitting lights on the floor against a wall.

[suzukir122]

not at all. lol... not many people know it, but fluorescent fixtures can also be used for style as well.

I should also add that that light was wired to overdrive the lamps (...its close in brightness to a HO light)

@suzukir122 8 footers are uncommon for aquariums just because most tanks are 6 feet long or less. (4 foot bulbs being the most commonly used) I can say that 4-foot 'aquarium' or 'plant-light' VHO bulbs are the same as any other standard 4-foot VHO (actually they're exactly the same size as a NO 4-foot as well).

For safety reasons, freezer bulbs will sometimes have a thin plastic-type coating so they won't shatter if dropped or hit with something, but you could use them as normal bulbs.

[suzukir122]

I have actually seen 8 foot vho's used in some of the freezers in some of the stores that I shop in... so those same vho fixtures that use aquarium bulbs can also use freezer vho bulbs? Those are the ones I'm trying to obtain.

@bamaslamma1003 The 4-lamp fixture that i crossed out? Yep It has 2 standard F40T12's & 2 F32T8's...(that one's really only there to keep my camera's auto-brightness "feature" from messing up the picture in the second half of the video when i show the startup)

[XmasLightsGuy]

I'm not even sure where I got that Feit electric bulb from, might have been at a garage sale, or maybe in some fixtures i saved a number of years ago before they went in the dumpster. I have a few older GE watt misers as well.

@suzukir122 Keep a watch on eBay for VHO/HO ballasts...now and then a good deal will show up (esp on non-electronic ones).

Most store coolers/freezers i've seen use HO ballasts/bulbs (although i'm seeing LEDs in the newest units). VHO seems to be mostly used for Plants and/or Aquariums (thats the reason i got mine...then never ended up using it)

[bamaslamma1003]

Are those regular F40's in the center fixture?
