What is the Luminous Flux (lumens) of this bulb?
489078
It offers 3 different color temperature of soft white 2700K, warm white 3000K, and cool white 5000K. 2700K is about 800 lumens.

I have not measure its lumens(no such instrument), and I feel it is ok - bright enough, and it is yellow hue.

I do not know. I didn't keep the packaging and there's nothing listed on the bulb itself. However I seem to remember it was equivalent to a 60W incandescent but that could be the ramblings of a 60-year old memory that's not always reliable.

According to the Wikipedia entry on 'Incandescent light bulb': "The luminous efficacy of a typical incandescent bulb is 16 lumens per watt, compared to the 60 lm/W of a compact fluorescent bulb."That would mean 20 lumens is about the same as a 1.25 watt incandescent bulb -- slightly less than 1/3 the light of a 4watt small incandescent nightlight. That's the theory anyway...

I don't have the email reply I received from the manufacturer when I asked the lumen output question. I believe it is 250 but it is very satisfactory never the less.

It is a T9 Circline bulb. The diameter of the bulb on the outer edge is almost 8-3/4". Energy used = 30W Claimed to be a 120W equivalent for incandescent bulbs, 2000 lumens. In case of doubt, call the vendor company for help. They are very knowledgeable.

I am sorry but the bulb I received does not fit in my lamp so I don't know the brightness.

The package I have is labeled 780 lumens. I see no mention of luminus flux.

Maker replied me - it's in 5,000K. It's Kelvin btw. Still no words on lumens though...

Not much. I can't tell the difference and I leave it on all night. All bulbs still work

It's 240 Lumens, which is great for a background desk light or low light setting. About the same as a 25-watt bulb.

I don't remember. It's been quite a while since I bought it. Full brightness is achieved immediately on this bulb.

It looks to be the equivalent of about a 10watt incandescent bulb. I bought 2 for my application to span the area that I wanted to light. I'm 100% satisfied after having these in use for months.

Lowes or Home Depot I believe they are 800 lumens brightness don't have it in front of me to check other specs but its written on the bulb also I bought a small laptop cooling fan and put up against vent without fan and it blows cool air in projector and fan on other side blows out hot air. This really keeps the operating temperature down.

I do not know the lumens value. But it is bright for the energy it uses. I would say it is equivalent to a 40 watt incadescent light bulb

1100 lumens. Compare that to what you have now. It replaced my 75 watt bulb just fine. You could always get a dimmer switch to if it's too bright.

It's 830 lumens total from what I can tell. By the way they DON'T use lightbulbs which means you CANNOT replace them once they burn out. Granted that in the case of an LED that will be 10years or more but even if one out of the four burns out after just a few years, you have to toss out the whole thing.

I contacted the seller and they said "the bulbs produce approximately 3840 - 4000 Lumens. Note that in comparison, the LED bulb directs light downward over a 180° area, whereas a fluorescent bulb directs light out over 360°, including towards the ceiling, so the light output between the two is similar."
