## Note : this next site also sells compact flouros in 56k (5550k)for replacing practicals!!! and after ordering some bulbs from here(T8- 4'- 5550k- 93CRI- 2960 Lumens!!), i found out that the engineer for the company is actually the same guy who invented the "KINO-FLO" brand of lighting.. AWSOME!!!

theres also new t12 electronic ballasts availabe which use less energy, and are super quiet with no flicker at all.  heres one set that i like for building your own kits. it takes t8 or t12 , but the t12 bulbs in 56k are generally easier to find, and cheaper..!!

Re: 5600k and 3200k flouro websites.

..they are just very very usefull if you dont want to mix color temps in a scene, and you need to replace you practical bulbs with somthing that outputs alot of light, but wont start the fixture on fire.. florescents as you know run very cool. you can even grab the bulb after its been on a while. so you can pop these into your practical sockets, and not worry about mixing color temps, and output alot more light if you want to. i think they are always good to have on hand..if not just to supplement some actual sunlight indoors by placing them just offscreen.
 
Re: 5600k and 3200k flouro websites.

Hey Iam, i was shopping fluorescents last week here in quebec city in places such as Home Depot and Wallmart. I don't have a very deep knowledge in lighting and I didn't have much success, of course i found some 5000k "daylight" tubes with a CRI of 92, which is very good, but it's only 40 watts and something like 2000 lumens! I am looking for tubes that are going to be able to serve as a key light, I would have needed 4-6 of those to do so !

Maybe you could give me a few advices on this matter. Thank you.
 
Re: 5600k and 3200k flouro websites.

..well, i actually think you would be suprised at how much light just 2 4' 40 watt florous will put out .. its enough light when used within an 8 foot distance to the subject (unless you prefer the bright as the sun type lighting setups). but yes, i would reccomend just buying a 4 bank fixture, or 2 of the 2 banks for a larger scene. but when using 4' florous you almost really only need them for key and fill lighting, especially if you have 2 of the 2 banks. the light is so soft that it wraps around everything just like indirect sunlight on a cloudy day. so alot of time you need very little or no fill at all. i would suggest just ordering sme of the 56k bulbs from the above links, and deciding whether you want to go with t12 bulbs, and pay 50.00+ for the fixture with nice electronic ballasts, and 7 bucks a bulb... or you can buy the T8 fixture for 8 bucks with an electronic ballast, but youll pay like 15.00 per bulb. the T8's are also more energy efficient, and you can run more off a generator. at any rate, what you should do is experiment first to see how much light you will need. if you can find a place with a single flourescent fixture, with 2-4 bulbs, take your cam there, and test out your exposure, and light levels, one 4 bank is alot of light, a 2 bank is often sufficient for any smaller scene like a small bedroom or bathroom or somthing in addition to any practicals, or sunlight. 2 of the 2 banks is nice all around, or 3 of the 2 banks is really nice. i wouldnt use it as a main light for any night scene unless it was supposed to be outside.. the light is way too soft for my taste for "dark" interior scenes. but again, just do some testing under a 2 or 4 bank (you can take out the outer 2 bulbs in a 4 bank, and the inner 2 will still run, so you can just use that for testing). i think youll find that 4 bulbs will do most jobs, and 6 to 8 has got your soft lighting covered for even greenscreen type stuff.
 
Re: 5600k and 3200k flouro websites.

do those 56k lightbulbs flickker? has anyone bought them?
 
Re: 5600k and 3200k flouro websites.

Thanks for the info Iam. I had 2 banks of 2 bulbs of 40 watts, but with the tests i've made it wasn't satisfying. I was trying to start from no light at all in a bedroom and see if a key light like this would work, but everything looked quite dark. So i made my own conclusions and told myself that maybe it wasn't the best choice for key lighting, but it's definitely the cheapest and i would love to find a way to make this work. Maybe with higher quality bulbs, those i had were "home depot's" Phillips 40 watts - 92 cri - 5000k, looked nice but only 1500-2000 lumens. It claimed to be "daylight" types of fluos, so i figured it work fine.

I also have a few questions concerning a few terms im not familiar with. The difference between T8, T12, etc? Is it just the diameter of the bulb? And also what are the advantages of an electronic ballast vs a magnetic one?

Most of the links from the US do not ship to Canada, maybe Jarred you would know an alternate solution for canadians who wants to buy fixtures/ballasts/bulbs ? ;D

Thanks alot guys.
 
Re: 5600k and 3200k flouro websites.

any flourescent bulbs will flicker or not soley pending the quality of the ballast your using (or in the event the bulb is bad), if your using a T8 bulb, they all use electronic ballasts, which have 0 flicker, and virtually 0 hum noise. they are ultra quiet. you cant really hear them unless you get very very close, and are very still. they do make electronic ballasts for t12 bulbs now too, but t12s use more energy, and put out the same or less light..so whats the point.. buying the electronic ballast for them is also more expensive.. they were made before electronic ballasts existed, and so the ballasts have been made to retrofit thier fixtures..t8's are the way to go . magnetic ballasts vary in quality too. but they all hum to some degree.. some are very loud. and the good ones wont flicker, but cheap ones will. again, if you go with a t8 setup, you never have to worry about either of these things unless a bulb goes bad. t8 electronic ballasts are also generally smaller, and only weigh about 1/4 of the wieght of a magnetic. and yes, t8 bulbs are smaller in diameter.

now the links i put up are all for either 56k (5500-5600) or 3200k bulbs they are not just "daylight" bulbs, as most daylight bulbs are between 5000 to 5250k and wont really be white balanced with your 5600k preset. which is the whole point of using the 56k color temp. they will however match most daylight, because daylight isnt a set 56k, it varys pending region, and time of day.. between 5000 - 12000k pending where you are and the time of day. its quite obvios that sunset isnt the same color temp as noon, so it varies alot no matter where you are. but again using exactly 56k or 3200k allows you to be sure of your color temp being consistant with your white balance preset, and you wont have to check your whites all the time.

now, im really suprised that you didnt find 4 4 foot 40 watt bulbs to be sufficient enough light for you. i have a room in my place that only has 2 of them, and i have to iris down , or face alot of overexposure.. now granted thats cuase i like to shoot wide open, but dont we all..(to get that shallow DOF) granted if your walls in the room are dark , and absorb light, it wont be as bright, but remember that with flouros, you can always put the fixture as close to the talent as the shot allows if you want, because they are not hot. but again i would recommend at least 4 bulbs for most soft stuff, and 6-8 will cover almost anything.. the only bad thing about the flouros, is that they dont throw light very far.. its not a focused beam. its very soft, and diffused, so it wont travel very far. when using soft lights. you need to generally be closer with the light than you would with a hard light by far. but as cheap as they are, you can buy alot of them and go to town if you need more light.
 
Re: 5600k and 3200k flouro websites.

ok..this is hilarious.. after looking far and wide for a cheap fixture that can handle t12 bulbs on an electronic ballast, out of all places, i find it at ...

wal mart.

they carry a "lights of america" brand fixture that will run 2 4' T12s OR! T8s off an electronic ballast.. only 14.00 . its hard enough finding electronic ballasts for t12s in th first place for under 40.00 but to find it for 14.00 AND! have the ability to run t12s or t8s is just outstanding.. WAL MART.. you have truley made a difference..lol
 
Re: 5600k and 3200k flouro websites.

yeah .. and he gest to just fly around the store dressed up like action hereos , and busting stuff up... must be nice
 
Re: 5600k and 3200k flouro websites.

Thank you very much for the detailed info Iam, i really appreciate. I just found some T12 around here at 5700k, 92 CRI, something like 2900 lumens. It Looks almost like something perfect for what i need, i couldn't find any decent T8s tubes or electronic T12 ballasts (the "kind of" fluorescent specialist around here said that it didnt exist hehe)...

But if i buy high quality magnetic T12 ballasts, i've heard that it should also work fine. What do you guys think about this solution?
 
Re: 5600k and 3200k flouro websites.

an exact model/make on those electronic ballasts from LIGHTS OF AMERICA would be appreciate, local walmart doesn't have them, and couldn't find them at lightsofamerica.com or using domain only search for thanks

http://ths.gardenweb.com/forums/load/wiring/msg0321302315127.html
references the fixtures being optimize for the more effecient t8 bulbs...

anyone with a walmart and these ought to check 'em out with the bulbs 93cri ~3000lumens bulbs iamloser referenced above.. walmart lets you return stuff forever.....later


for reference, kino flos themselves for daylight are 5500k, 40 watts and 2330 lumens, 95 CRI

Re: 5600k and 3200k flouro websites.

a high quality magnetic ballast fixture should work fine, but your using more energy.. waiting longer for thr bulb to reach its full luminance, and could possibly deal with some hum or flicker on occasion still pending your power scource. i would test it out if possible. but t12 electronic ballasts do exist.. in large quantities.. in fact i posted a link to one above. and that one runs t12's or t8 too. and its for a fish tank.. lol but they do make them for any fixture. ..

anyway, its just a generic Lights of America shoplight with a stainless steel backing .. heres all i could find at thier site:

http://www.lightsofamerica.com/sl.htm

and that doesnt even say it has an electronic ballast, or that it can run t8s.. ill try to post the info here later when i can look at the box.
 
Re: 5600k and 3200k flouro websites.

i don't get it, the forums says TODAY at 5:55am, iamloser replied to this topic, but i don't see anything, posting this to see if shows up...now it did, and NO, there was no PAGE 2 link for me... hehee, keeping this here for now, strange, willk remove it later

might as well add this...
http://www.bhphotovideo.com/bnh/controller/home?A=ShowProduct&index=Y&kw=KIFF200FS&Q=&O=&sku=258722

if you do it yourself, it almost looks like you could add your ow    ectronic ballasts/fixtures inside there..

in addition found:
CRI 98: Crompton LA29347, Osram Dulux/12, Philips F32T8/TL950, Kino Flo
K55 482-S
CRI 95: GE Cinema 55, Philips 'TL'D 36W /950, DuroTest Vita-Lite Supreme

can't find where to buy the ge 55's looking for the rest now
 
Re: 5600k and 3200k flouro websites.

Well, here may be an annoying newbie post, but here it goes:
To round out a decent , albeit, minimal (low budget) lighting package, What should I consider in flourescents for lighting (more specific the better)

I see talk of buying from Wal Mart (which would, of course, be great for me!) Should I get 2 four banks, and what other equipment do I need for them to give me light without flicker or greenish sickness (BTW I'm not going for any crazy lighting looks, just natural daylight or indoor night stuff, no fancy dream sequences and stuff) Thanks alot, oh and feel free to assume I know nothing (which isn't far from what my friends say) :-/
