What is the measure of light that is emitted? bulb wattage?

For the medical therapy effect the most meningful unit of measure is lux, i.e. the intensity of the light impacting the human skin or ear tissue. Valkee's light intensity in the ear canal is about 10,000 lux, which corresponds with the intensity of big tabloetop bright light lamps that need mains electricity. 10,000 lux is also the required intensity for bright light devices to be approved for medical insurance reimursability in the few countries where it is a reimbursable insudred cost for treating SAD.

The bulb is LED hence should be low wattage, but what is more important is the measure of the total "amount" of visible light emitted by a source in unit called 'lumen'and its 6.0-8.5 lumen of bright light.

Maximum luminosity according to the small book that came with the valkee is 3.5 lumens. The LED light intensity and duration can be adjusted via valkee login that is assigned to each device much like an ipod is reset. Hopefully this helps.

Pretty hard for me to measure because it is intalled up high in my ceiling but it was a drop-in replacement for a GE EXN 50W 12 Volt bulb. I noted no size difference when I did the job. Hope this helps.

Can't be measured. They are led bulbs & battery operated. Love mine for our travel trailer. I plan on ordering 2 more for next season.

Bottom is open and I used a clear bulb so I cannot read the wattage. I think it is 60 watt. This might be the nicest light fixture I have ever purchased.

18 watt bulb. The bulbs last for years. Amazon sells the bulbs. It is the best lamp ever.

Used standard 60 watt bulb. Lamp used as accent, does not offer significant light for reading, etc.

Well, there's no brightness equivalent stated on the product, but it is definitely brighter than I thought it would be (which I like). I would say it's at least 60W equivalent but not quite 100W. Also, I ordered 3 bulbs but one of them burnt out premature.

Note this is actual watts, a measure of power, not "watts equivalent" that some use as a measure of brightness. It is way more bright than a 60-watt incandescent.

LED is measured in lumens. However I don't know how to convert it. http://homeguides.sfgate.com/lumens-vs-watts-led-bulbs-78825.html I found this sight- it might help.

We have it over our kitchen table. It has two 60 watt bulbes. We have plenty of light.

I don't have the exact measurements, but it seemed the same size as a standard incandescent light bulb.

I'm not sure I understand your question, are you talking about the energy used or the amount of light produced.The package says the bulb consumes 60w of energy but puts out nearly 250w. I have two of these and I can say they are very bright.

dimensions are about the size of a 194 bulb, for a T10 socket. i'd say light output is just slightly dimmer than a 194 bulb, cant say on actual lumens though

60 deg. Over all light. There also 27 watt per LED. Two of these turn night into day. I own 6 sets. Very bright.

up to 100W. I have a 60W bulb in it, and that's about bright enough for me.

It is fairly bright I'd estimate 40W or 60W equivalent. The light is not as warm as I was hoping for though. It is more daylight than warm.

We use it like a nightlight, but it does dimly light the entire room. I'm not sure what watt bulb it compares to.
