LED 'fluoro' tubes

[Phil Allison]

"Petzl"

Some places ban the use of fluro's around saws.
Saws are noisy a lot of idustry have more than one saw going and
strobing fluro can make a saw blade look still

** The solution used in industry is to run all the fluoros from 3-phase
power with three tubes in each fitting each on a separate phase. Cancels out
the strobing effect.

Thanks the way around I see was to use combined with mercury vapor or
incandescent!

I'll bet there's a lot of factories, work places, etc., that don't have
it done right tho

not worth it tho until the cost comes down

My cellar/workshop has one 4 foot flouro fitting which cost less
than $5 with tube. There is another light, a 23W spiral CFL that
fitted into an existing fitting (the CFL cost just $2).

Maybe we'll have to buy LED replacements in ten years or so when
current flouros expire.. because they'll be the only thing on sale
by then.

Bet they aint.

Any predictions?

That they will be around for as long as anything else, essentially
because they are so common in non home situations.

Or maybe your iWank wearable technology will have eliminated the
need for room lights

Just another of your pathetic little drug crazed fantasys.

Another ad-hom,the only resort of a brain-dead fool.

Nope, statement of fact.

Only in your tiny mind.

Nope, statement of fact.

Grow up.

Retake Bullshitting 101.

Pathetic.

High pressure sodium (and Alsynite skylights) seem more common in the big factories
I don't know if the sodium lamps strobe, or how much. they're cheaper to run than
fluorescents.

The chart on that page seems to show that they are worth it -
presuming that the chart is correct!

Or have I missed something here?
Seen them at ALDI $13 for 4 foot ones

I bet they don't emit as much light as flouros do

I tested with a lux meter and they were almost identical at one
foot.

so you have some then? I have some edison LED bulbs. they are ok in
desktop or bedside table lamps, but pretty well useless as ceiling
lights.

Bullshit, I have replaced all the 15 watt CFL ceiling lights in the
house with 7 watt LEDs, the light is far better and they come on
instantly. Also replaced a 32 watt flouro in the kitchen with a 15
watt
LED fitting which also gives far better light.

That's my experience as well. LEDs beat the piss out of every other
form of lighting. In some of my smaller rooms, I only run 2W globes,
as I do in the hallway and desk lamps. Most others are 3 and 4W around
the house, and are more than bright enough for me. I also have a 13W
1200mm 'fluoro' tube, which is almost too bloody bright for the
kitchen (kitchen also has a 4w globe in a down light). Even my fridge
has a 1w LED globe.

I hate the light from flouros, they remind me of every office that I've
worked in and 1960s houses. They also put 3rd harmonic distortion on the
mains when used en mass.

Big problem is the *colour* of the tube you select.

Yep.

Just noticed the CFL in the bedroom is yellow, works fine.

Having measured them I found that most modern high-frequency ballasts
for linear fluorescent tubes don't produce any significant 50Hz or 100Hz
flicker. (They have some at 50kHz+ though.)

It's odd that some people still seem to install the old inductor based
'magnetic' ballasts in Australia, and the price of the high frequency
ballasts is quite high here.

The crappy cheap ballasts built into CFLs are much worse than the ones
for linear tubes and seem to flicker strongly at 100Hz (and also many
kHz, the combination of which stops many IR remote controls from working).

Sadly a lot of the new dimmable LED lamps also have very obvious flicker
at a few hundred hertz. I have no idea why they would choose such a low
PWM frequency for the dimming (unless they use some crappy slow
microcontroller and a very rudimentary PWM algorithm, and use a low PWM
frequency to get dimming resolution because they are not up to writing a
sigma-delta modulator for the PWM). Anyway they flicker so badly that I
wouldn't use one of those to read by, let alone over a lathe.

My info is that it is not that easy to buy HF ballasts for T8 or T10 fluro
tubes - only those for T5s which can use no other are easy to buy.

You'd lose that bet.
I tried some LED screw in ones in ceiling fittings. they do not
illuminate the room like flouros or incandescents do. they don't seem to
disperse or 'throw' the light
Hmm. As I progressively changed my CFLs to LEDs, I was always mindful
about light levels. I couldn't see much difference, other than when I
went to really low wattage LEDs.


this was a while ago when they first made an appearance. maybe the ones
they have now are better, and/or the design is relevant

Or you should be replacing them with a comparable wattage LED's,
something you probably overlooked.
