What is the lumen output per bulb?

is a measure of brightness. Gives us an idea how long it will illuminate. The problem with these bulbs is that they have a very linear light, is that the whole environment does not shine.

I'm not sure of the lumens. I am using them as day time running lights and back up lights.

Per the box, 300 lumen. I replaced 12 35-watt halogens with 12 of these, and have more light at one-seventh the wattage. A terrific product.

The manufacturer specifies the output as 200 lumens. It is quite bright, considerably more than the stock xenon bulb. http://terraluxportable.com/product/ministar-srn/

I doubt the lumen output is anymore than 50. These bulbs were a complete waste of money and are not powerful enough for driving at dusk let alone at night.

It's a little over 100 lumens. Those who wrote 200 and 300, are only comparing output to generic lights that are fraudulently rated higher than their actual output.

The lamp is halogen (lamp type determines the conversion ratio) . So, the conversion is approximately 20 lumens per watt. I don't remember the exact wattage of the lamp it came with. It is probably 190 watts (you may check it in the instructions it came with). It is, therefore, about 3800 lumens.

This is an 85W florescent energy, I assume it will be the equivalent to 200W-300W incandescent. I have no idea how many lumens it generates, but this bulbs are very big and bright.

Don't know the specific output but it is bright enough to illuminate my flag over night but only at a close distanceof 2 ft.

250 lum. These are great bulbs! I have ordered 20 of them so far for my Class A motorhome and enclosed motorcycle trailer! So much brighter!

Not sure about the lumens capacity but it is probably the brightest regular bulb on the market. LEDs may be brighter though.

I don't know the lumen output, but the light is for effect only. It is very low light. Also, the batteries do not last more than one season without replacement. I have had these 3 years and that is my main issue.

I don't know about lumens exactly, but I measured the output with a light meter and it registers about 15k to 20k lux (1 lux is equal to 1 lumen per square meter, I think). They say 20k lux is legit for growing plants. I ordered 4 different types of grow lights, and this actually has the highest output (including a 60 dollar T5 setup), it just doesn't cover a whole lot of area, although definitely covers more than the other under $20 LED lights. I may buy quite a few of these.

My package says "80 Lumens Max". I love mine. Very bright when batteries are fresh. Just be sure to use good batteries. I use rechargeable and they usually only last me a night or two before the light starts to fade away.

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.

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.
