I wonder what is the actual reading for those CFL bulb and LED bulb. 

Those seller never tell the truth and just simply quote from the book. While consumer don't have a reading but just said "bright" or "not bright". But how bright is bright? The arguing is continue.........
Hi, good job comparing those,

ok, i think the way you measure give you inaccurate information,

first, the big manufacturer won't be wrong, especially those big company, because it need to be certified by 3rd party like TUV, ITS, etc

the way you measuring CFL including the reflector, take away the reflector, you will get very similar lumen figure from the box manufacture stated
a good reflector will boost your lumen reading by a lot, reflector can cost as cheap as 3 ringgit to 50 ringgit.

2nd, lux reading is usually base on min 1 meter away from the light source,  but lux also have to calculate with a lot of factor

1. light with reflector or not, and its angle, because you can measure in diff angle and it give diff reading, some reflector gives more lux in diff location

2. your surrounding, wall color, any mirror reflector, windows, how you hold the meter, floor color , furniture , etc

3. usually we design using dialux we will calculate average base on one area, we won't take one reading, because rarely your room only have 1 bulb or downlight
    usually we have minimum 4 and we calculate base on the ies file from manufacturer, now when we do that, all those above factor have to be included , then the distance  you mount the light and the angle of the lights coming out of the fitting is important. of course like you say, actual and spec is very diff

4. lux also depends where you read it, we take usually for household , ceiling (light source) to waist level, not to floor, because how often you lie on the ground and read or making pastry or doing something on the floor, except for baby, then we calculate lux to the floor

lastly,

following is MRT spec for the station ; min lux (measure from light to floor)

general area, 150
ticket area , 200
platform area, 300
escalotor , 250
stairway , 175

my recommendation, well just my company opinion or my personal , everyone is diff, of course more lux better
reading - working - writing - 300 - 350 lux
assembly small item, hobby making model, 450 lux
cooking - making pastry - 300 lux
hall way 150 - 175 lux
living room general lighting 200 lux

anyway, how much you bought ur CREE LED ?

This is CREE ecosmart CR6 LED downlight rate at 10.5w and 575lumen. Come with 3year warranty. Meter read at 17,590lux.
pretty low lumen, average now 10w downlight is about 1000 lumen !

if someone have a new LED measure it when is new, and after 1000 hours measure it, and 10,000 measure again. The LED can last but brightness may not.

If you got a brand new un-used LED put it on and measure. So you now have new bulb reading and 3600 hours LED bulb reading

Hi, the theoretical the product will last as the design specification or at least the test results. but the world is not ideal, there are so many factor that causes the LED driver to fail. Well to be fair to LED, non of the CFL product last as advertise, i.e. 8,000 hours, most of them fail after 2000 - 3000 hours. if you lucky it may last until 5 or 6K. but they are much cheaper to replace , so people ignore it.

ya, for normal house hold , we just gauge using our experience or by the rule of thumb
if you guys are interested, read the following article

if pretty much rule of thumb, however it is pretty tricky to apply to LED
well my product RM 128 - 138 , give about 1100 - 1200 lux depends on temperature, let me know if you need any to test

well , i am not expert, just sharing on my experience, you are pretty good having a nice lux meter to measure those, i mean we just us dialux, the actual when we measure sometimes is off ... hair ... people say light design is ART , i am really a lousy painter then ... lol ...

The correct question is , which is not manufacture in China hahahah ....
most of the chips and drivers are made from there ...
well, China do make very hi-spec LED, no brand customise product, for those hotel, casino, airport, etc
they are very nice, nicer than all the brand out there, but price also very nice
