Is there a difference on how they test?

I know they can squeeze more lumens out of CFLs for a given Watt. However, they usually do so at the expense of decreased operational lifetime. A few of the CFLs we used to have would start to burn and melt towards the end of their lives.

FWIW, the spiral type CFLs produces more light than the traditional 'straight' ones but usually costs more.

Several months ago, I compared four light bulbs that can be seen in post 36 of this same thread: http://tsikot.com/forums/science-tec...ml#post1989530

the parking area of 6750 has already replaced their fluorescent light tubes to LEDs. its much brighter na. also noticed the used GES brand. looking at the tubes, you wouldnt notice that its LED. you wont see the LED chips kasi.

Back in March, I have replaced the standard 20 watt fluorescent tube over my office table with a 10 watt "tube" style LED. It is easily twice brighter than the old fluorescent tube and it doesn't even got hot.

If placed on the right spot, bro.

It is easily X3 or X4,- so a 10W LED is equivalent to at least a 30W CFL.

Latest count, I replaced almost 40 CFLs in our house with LED bulbs....

And, about half of them are turned on all night....

imho, mas maganda yung spread ng ilaw sa spiral compared to LEDs...haven't seen one that throws light at the sides as well.

Maybe it's because of the low ceiling, but the LED bulb i bought for my room just doesn't quite cut it. Planning to experiment with an LED tube. i bought one from CDR King for my fish tank, knock on wood di pa naman sumabog o lumiyab

That's my problem with the LEDs I used to replace our outdoor 25w CFLs. They're just as bright, but most of the light is going the wrong way. Really need to put a reflector in the housing better than the cut-up foil-covered paper plates that are there now.

Switching to LEDs will sometimes require looking at some design considerations. If it's outdoors, you'd want a weather-proof lamp holder and ideally a sealed LED parabolic (PAR) lamp to have better control on where you want the lights to be pointed at.
