Light Bulb Suggestions

Postby DreadArchon » Tue Apr 01, 2008 1:33 am UTC

The 60 Hz operation of fluorescent lights sometimes gives me a headache. With the moratorium on incandescents, I'm looking for good light bulb replacement options.

Suggestions?

(I did look around on Google a bit, but I'm not very good at internet research, especially when I'm fuzzy on the details of what I'm looking for.)

I can't really answer your question, but how do you know that that's the cause of your headache?

It's not like it's blinking the same way CRT monitors do. Yes, the polarity switches, but it's not like the metal cools and stops glowing while the voltage is crossing the zero line. The intensity only varies a little.

How about halogen-based bulbs? They have absolutely no flicker and are a lot less dreary than incadesents in terms of color. I quite fancy them due to their brightness, however, the fire hazard associated with them keeps me cautious of how long it stays on...

This. Also, I'm trying to limit excess heat generation as much as possible because my room gets too hot due to a bad air flow in my house. (In my experience, the difference between halogens and other bulbs is noticeable in this regard.)

As for the fluorescents: I'm not totally sure that it's the bulbs doing it, but paying attention to my surroundings when I get headaches "like that" makes me think it's the lights. (Also, I have known a couple of other people who make that claim.) Yes, it's mechanically a minor effect--then again, I did say "sometimes."

Some people just have problems with strange things, you know?

(Also, at this point, I have become curious and would like to know about lightning options "just because." :wink: )

Dude, it sounds like you're gonna have to get a shit load of glow in the dark stickers and let the sunlight recharge them every day!

If heat is an issue, that takes out...
Halogen, Incadesents, candle light, oil lamps.

if flicker is an issue, that takes out...
flouresents.

Am I missing a lighting option, 'cause really thats all I can think of LOL!

There are also LED bulbs, but... they're extremely expensive. And dim.

I wonder if they would cause his flicker annoyance as well.... they def. wouldn't generate heat, but with enough of them surely he could overcome the dimness dillema...

Do you not have those small twisted screw-in fluorescent bulbs? I use them and can't tell any difference from incandescent bulbs, plus they're way more efficient.

i'm going to butt in and agree that the twist-in flourescent 100w (x2) in my ceiling fixtures are fucking awesome. the color of the lighting is so much more pleasant and easier to work in...

Agreeage with drop and tap.

Also, I just realized I mixed up incandescent and fluorescent (english is not my mother tongue). My first post was about incandescents :oops:

I probably should have looked into them a little more... looks like you can get LED bulbs that fit in a standard socket and are the same brightness as a substantial incandescent. For instance, here is one that claims to be the equivalent of a 60W incandescent; assuming the lumen output is correct, that is just slightly dimmer than what Wikipedia says a 60W bulb should be.

Now, that said, it's $120.

I can somewhat confirm the headache story, I get that too, especially from being in a room with nothing but fluorescent tubes. LED's are indeed your best bet, but the lightbulbs are really expensive. If you could build your own array, you could easily get some really cool (in every sense) high-efficiency lighting, but it'd cost you some money and a lot of trouble. Or some trouble and a lot of money, depending which you'd rather have.

I've been building a computer-controlled light dimmer, and specifically went for incandescent bulbs for this exact reason, they're still the cheapest stable, dimmable light source. LED's are expensive, halogen won't like dimming, and fluorescent stuff gives me a headache. Or at least some odd feeling at the back of my eyeballs.

The fluorescent flicker problem depends on what sort of fitting you have. Most older linear or circular fluoro fittings have fairly low frequency ballasts (even some cheap new ones do), which causes the flickering. You can replace the light fitting with one that has a high-frequency ballast if you want to, that would solve the problem. If it's a compact fluoro that fits into a normal screw-in or bayonet socket, however, you've just bought some cheap-ass bulbs. Spend the extra dollar and buy one with a high frequency electronic ballast, for crying out loud. Philips, GE and Osram brands are recommended. If you've bought CFLs before you're probably aware of this, but pay close attention to the colour temperature on the packaging. 2700-3000K will give you a light roughly analogous to an incandescent; 4000K is supermarket off-white colour; and 5000K+ is similar to natural sunlight. Pick one to suit your application and tastes.

If you really hate fluoros anyway despite this, there are halogens on the market which have a standard ES/BC socket. A 60W halogen shouldn't be as hot as a 60W incandescent, on account of the fact that it's more efficient - if you compare the two, the halogen would look brighter. (It'll still burn if you touch it, though, so...don't.)

Edit:
halogen won't like dimming

Say what now? Whoever told you that is on crack. 120/240V halogens work just fine on dimmers, 12V halogens require you to check the transformer to see if you need a leading or trailing edge dimmer, but they can still dim.

Huh, that's news to me. I've never seen those. Do they not have the usual increased fire risk of other halogen bulbs? (I was never really clear on how that worked.)

(Also, do LED or halogen bulbs oscillate like fluorescents? As you can probably tell, I really don't know much about lighting technology.)

:nod nod nod: Theatrical lamps are halogen. They do a lot of dimming.

Agreed, I forgot to explain that using a seperate dimmer, not one built for the halogen bulb, isn't a good thing. Depends on the type of dimmer, if it chops or just lowers the amplitude. At least, IIRC.

Is it possible for you to move your light source? Indirect lighting might fix your problem without replacing bulbs.

I think halogens have that rep because they're generally stupidly powerful, from 150 to 1500W or more. The screw-in ones I've seen have a small linear halogen element encased in a standard-size glass bulb, which prevents people from getting too close to the very hot element. As I said, it's still dangerously hot to touch, but not quite to the same degree as common, more powerful halogens.

AFAIK, LEDs and halogens won't oscillate or flicker. Fluoros do it because of the electronics inside which convert the power into something more usable by the tube. Halogens work very much like normal incadescents in that they're essentially a piece of metal with power running through it, generating light and heat, so no flickering. I'm not quite up to scratch on the latest LEDs, but to my knowledge they're still diodes, which means electricity will only flow through them one way, so oscillations are difficult. The only flickering I've seen in LEDs (or halogens, for that matter) is because of power supply fluctuations.

Hot glowing metal is not how fluorescent lights operate.

I didn't see that post, even though I did look over the thread before responding. Sorry.
