CFL Lamp Question.

[Montek]

Bought CFL lamp today, that replaces normal lamp, though when i turn it on, its slightly shining, is it waste or you had to give it few minutes to lighten up?

Sometimes it takes a few minutes.

Takes a few minutes to warm up to full rated lumens.

I personally hate those spiral lamps, they burn out far too often due to power fluctuations.

I've had mine for over a year now with no burn outs in 15 spots. I put them in after getting sick of pulling out a 13 foot ladder to change the bulbs way up in the ceiling. Mine dont really need to warm up, either. They are very slightly dimmer (maybe 10% less than full) when cold, but that's about it.

Yep same here. If you have CFL lights burning out then you have problems that need to be fixed. i.e. wiring, sockets, outlets, breakers, etc...

Only ones I have seen take a long time to warm up are not the spiral ones, but the ones shaped to look more like normal bulbs. Have never had one burn out on me yet either. Just remember to not use them or not expect long life in places where you are turning the light on and off a lot, such as closets.

Doh this Philips CFL were heating for around 30 minutes and did not make any progress, i think i going to turn it back now.

Check ther voltage at the socket and also what did you take out (75watt, 100watt, etc...) and what wattage did you put in (9, 12, 13, watt?)

220V (europe) 125W what u mean what wattage i put in, it says 23Watt energy on box.

when you say its slightly shining does it mean its really dim, or just slightly not as bright as you want.? check the lumens output, if its only 1500lumens vs 1750 for a white 100watt incandescent it might be very slightly dimmer, i dunno. almost all bulbs these days reach full brightness within 1 minute or less.

An offbrand they had at home depot. They were on sale for $1/bulb.

 

[Demon-Xanth]

<-- picked up some off brand bulbs for about $6.30 for 10 60w equivalents and $3.70 for 6 100W equivalents thanks to power company instant rebates. I wasn't too surprised when one was dead out of the box.

Its was slightly even seen, replaced with working one, it lights bright next second its turned on and reaches full brightness in about less than minute.

Though it has 1550 Lumen (btw its first time i hear of lumens), i curious what would be brightest CFL that is equivalent to normal incandescence lamp in size, sales man told he havent seen more than 125W yet.

 

[Demon-Xanth]

How's 2700 Lumens sound?

For 6000!

I were talking about ones that fit in standart holes...

Btw whats more important then Luminous Flux
or Watt's? I mean lamp with 125W and 1500 Lumen is less bright than 45W and 2500 Lumen?

 

[Demon-Xanth]

Watts is power consumed, or often "equivilent to...". Lumens is the actual measurement of light out.

Why normal incandescence lamps marked with Power in Watt's and not lumen?

 

[StageLeft]

I am replacing many bulbs with CFL, but they're still quite an ugly light. I have had one burn out after a couple of months but the replacement bulb has been going now for at least 4.

My main kitchen CFLs seem to brighten immediately. The ones I Buy take 60 seconds for full brightness.

Why normal incandescence lamps marked with Power in Watt's and not lumen?

That's just how it is, and more watts generally equals more light. It does with CFLs, too, but using te watt measurement is not relevant with CFL vs watts from incandescent, though all the ones I buy do have the "equivalent to 100W", for instance.

Because lamps and sockets can only support so much current and heat. The box often DOES say lumens.

ie: the 50W bulbs I have are marked as 820 lumen

manbearpig says you must use CFL

I have never seen a filament bulb box that listed lumens. Same with flashlights. They guard that information like it's fort Knox. Then when they do give it to you, you can't mentally compare because no one else does.

 

[irishScott]

I bought 2 of these: http://www.nvisioncfl.com/images/products/150-127.jpg a couple of months ago. They take < 1 min to get to full lumens, and neither has shown any signs of burning out.

3 brands, all list the lumens right there on the box. Maybe you're buying blacklights.

You need to look harder if you can't find it on the box. GE and Philips both display the lumens rating pretty clearly on their packages.
