Author Topic: Incandescent light bulbs rule. Steve Guttag We forgot the crackers Gromit!!! Posts: 12814 From: Annapolis, MD Registered: Dec 1999 posted 11-27-2007 12:21 PM                     I dunno...I find Florescence to give off a greenish cast more than anything. Even in photography there various light magenta filters to correct for this. FL-D and FL-W come to mind for Daylight and White versions of lamps.

Factor in the electronic ballast, the drop of mercury, the added manufacturing processes, the extra weight to be shipped I'll bet they are dirtier that incandescents.  |  IP: Logged Louis Bornwasser Film God Posts: 4441 From: prospect ky usa Registered: Mar 2005 posted 11-27-2007 03:00 PM                        Green style fluorescents are really great in my magnetic work lights (on a mike-style flexible arm). They are bright, cool, and most of all don't fail when dropped. They don't burn you when working "close."

There are indeed dimming systems made by both Colortran(now owned and completely screwed up by Leviton) and Strand Lighting that can dim down to the 12% realm before the lamp goes out. It requires both special ballasts and special dimmer modules to achieve though. One of the last lighting related jobs I did at GTS was to commission a new system with Colortran Dimmers in an Art Museum at a university. I never thought the flourescent end of it wold work but it did indeed. It was actually pretty impressive as they didn't change color temperature very much through out the dimmable range.

Agreed completely - the chemical goo produced by manufacturing the PCBs and plastic must create as much if not more toxic emissions than the increased power consumption of a glass/metal/filament bulb during an average lifetime. I do use mini-incandescents for all the lights in my flat except the ones I need to read under: not out of any worship of the Swampy brigade, but simply because they cost about the same to buy (the supermarket chains here are now selling them as loss leaders to burnish their green credentials) and less to run. But attempting to read under them gives me a headache, so I do have a 40w halogen spot on my work desk.  |  IP: Logged Jeff Stricker Master Film Handler Posts: 481 From: Calumet, Mi USA Registered: Nov 1999 posted 11-28-2007 02:58 PM                     Edison invented the incandescent lamp in 1879. In 1929, Henry Ford threw a lavish dinner party at Greenfield village to celebrate the 50th anniversary of the invention. Edison, among other notables was in attendance. That was in 1929, it's time to move on with beter more energy efficient lighting.  |  IP: Logged Joe Redifer You need a beating today Posts: 12859 From: Denver, Colorado Registered: May 99 posted 11-28-2007 04:57 PM                        I agree. Someone please invent better lighting. The light coming from these turd coil lamps is pathetic. I'll throw this out there as well: Hybrid cars are also pathetic. They get less MPG than my REAL car and cost much more. Therefore hybrid = retarded.  |  IP: Logged Leo Enticknap Film God Posts: 7474 From: Loma Linda, CA Registered: Jul 2000 posted 11-28-2007 05:07 PM                        And again, how much Co2 and other toxic waste is produced, and energy consumed, manufacturing (and, at the end of their life, disposing of or recycling) the electric motors and batteries, relative to the energy and emissions saved by the hybrid during its service life? There's no denying that peak oil will become a reality (the only dispute is when), and that we're going to have to find ways of powering our homes and transport that don't need fossil fuels. But when the CEO of Google said that he was investing in a research programme to try and produce renewable energy at a lower cost than generating it by burning coal or oil and with a lower energy input to output ratio, and that until he'd found one renewable energy was basically just a side issue, it was refreshing to hear someone talk sense at last.  |  IP: Logged Jack Ondracek Film God Posts: 2348 From: Port Orchard, WA, USA Registered: Oct 2002 posted 11-29-2007 11:07 PM                        Why is it that the passage of time qualifies as a reason that something must be changed? Fluorescents are fine for some applications, especially if lamp life is a main factor. For a sense of warmth in an environment though, I'd put in an incandescent any time. Personally, I've never picked a product off the shelf and evaluated it based on how long ago it was invented. Guess we'd better be tossing our phones, too... all of 'em! That nasty AC and DC has also got to go... look how long that stuff's been around! We must immediately cut the cables on any elevator that's been in service over 20 years. I rode a 1940 Otis the other day... yeech!  |  IP: Logged Randy Stankey Film God Posts: 6539 From: Erie, Pennsylvania Registered: Jun 99 posted 11-29-2007 11:39 PM                     Don't forget! Fluorescents don't work well in cold temperatures and they can take a second or two to come on, even in warm temperatures. For lighting outdoors in cold climates and in places where safety is critical, fluorescents are actually contraindicated.  |  IP: Logged Joe Redifer You need a beating today Posts: 12859 From: Denver, Colorado Registered: May 99 posted 11-30-2007 01:26 AM                        I have a couple of fluorescent bulbs that turn on immediately when the switch is flipped, no delay.  |  IP: Logged Frank Angel Film God Posts: 5305 From: Brooklyn NY USA Registered: Dec 1999 posted 11-30-2007 03:33 AM                        I don't know about the color issue. They seem to have overcome that greenish, cold white thing. Our offices burned down awhile back and when they rebuild, all the lighting was florescent tubes (none of the compact curly "turds" as Joe so colorfully calls them). As soon as I heard it was going to be flourescents, I got all set to huff and puff about how terrible the color would be and how everyone would look sickly. Well, I was very pleasantly surprised that they installed these improved tubes that have nearly the same color as incandescents and much more efficient; they are skinny tubes, about half the diameter of the older tubes that have been around since we were kids. Everything in the office is very warm looking. It's all indirect lighting too -- everything facing the ceiling so you never see any of the tubes. Everyone is really pleased with the whole look. I, on the other hand, feel cheated that I can't bitch and moan and pound my desk about how I refuse to work under ugly, epileptic fit inducing flourscent light.  |  IP: Logged Richard Fowler Film God Posts: 2392 From: Ft. Lauderdale, FL, USA Registered: Jun 2001 posted 11-30-2007 07:47 AM                     There are many options for color temperature + suppression of "green" spikes on new flourescents. High frequency ballasts replacing the "buzzy" 60hz magnetic type make working under them more tolerable. Those skinny color corrected tubes are replacing bulky tungsten softlight fixtures on film and video shoots more often in the past few years.  |  IP: Logged Mark J.

Then I replaced the bulbs in there with these special "kitchen and bathroom" type lights that are supposed to create more natural lighting. It really made a difference! The popcorn even looked better. One of our concession girls (a 17 year old) walked in that night and immediately said, "The lighting looks way better in here...what did you do?" So if a teenage girl spotted a difference, I knew it had to be a real improvement.  |  IP: Logged
