What is the total wattage of this lamp? Is it a noisy magnetic ballast?

I haven't checked the total wattage but it should be well below 200W. The transformer is basically silent during operation but might make a little noise during startup, which takes a minute or two.

No idea. It seemed to be about as bright as a 300W PAR56 lamp. Btw, it stopped working within weeks.

I never found out. The lamp might be OK, but the fixture it sits in could replace Hoover vacuums for shear sucking power.The ballast cannot be replaced in the light without tearing it apart.

This bulb consumes sixty watts of energy and the light output is about the equivalent of a three hundred watt incandescent light bulb. In other words you get a lot of light for 60 watts of energy input. Or putting it another way, this bulb draws about a little more than half an amp of current. I have been pretty happy and so has my plant with this bulb. Hope that this answers your question.........Josef

It doesn't say the wattage - it comes with a bulb which reads: Marineland Natural Daylight F15 T8/18". Hope this helps!

Sadly, it isn't. I was also looking for cordless lamps when I see this but I wasn't able to help myself from buying it because I find it really simple but elegant. Just a suggestion, if you want to feel cozy using this lamp, I recommend that you use a 40W Equivalent LED Globe bulb. They are bright enough and this one's quality really deserves a thumbs up (Pack of 4) G25 LED Bulb 6W, Warm white, 3000K, 40W Globe Bulb Incandescent Replacement, clear Cover, Dimmable, UL Listed, Energy star certified,

All of these mini florescent bulbs have small ballasts in the base that control the lighting. They can and often do make a buzzing noise. I have 20 of the 45W lamps and only a few buzz slightly after warming up. I usually have music on when I use them, so it's not noticable for me. If the buzzing is really loud to you, then you might have received a defective batch, in which case I would contact the manufacturer.

From back of the Germguardian: 3.5 Watt, 11 Volt. I believe my lamp is now ~1 yr old and I am under the impression (I have forgotten the source) that replacement may be needed this year before it fails, from decreased UV output.

No, use a thousand watt bulb in a thousand watt ballast. The dimmable feature , like on here will dim to 750 watts and down to 500 watts. I had this unit for 23 months and went sour. No went with another brand - Apollo 1000- the quantum company wouldn't help me unless I had a contract, the grow store , from SoCal forget the name, they wouldn't honor the 3 year warranty and Anazon wont after 30 days. Just my experience and I bought the Quantum wen it was $300. Apollo 1000. 189 just as good.

the ballast has to be HPS and wattage compatible. if you can afford it, the best is the dual arc 1000w

It should either work correctly or not at all. If you have access to an old-style magnetic ballast fluorescent light, point it at the light and take a reading (light on, of course). You should get a reading of 7200 rpm - the light actually turns on and off twice with each cycle of the AC power, so 2 times 60 cycles per second times 60 seconds is 7200. This may also work with mercury and sodium vapor lights, but it will not work with more modern lights with electronic ballasts.

I don't know the wattage, but I can tell you that I have it in a very sunny area and it still doesn't let off very much light.

No power consumption is given - it is a very bright array of LED's (28!) - almost too bright for my purpose of a key-board light - almost like a small desk lamp.So, based on brightness alone, it is not the lowest one out there for low power. Good light source however -

Dear buyer:Thanks for asking .55W AC ballast will brighter than 35W ballast.And 55W quality, stability are better.Thank youSean

About 3 hours is probably the longest I've used the lamp (I use it in my sewing room). I use CFL 120v 14w and don't recall that it got hot.

I use a 40 watt bulb, and it casts a nice warm glow. I have to warn you that I bought one for myself and one sent to a friend. Both lamps were very poorly packaged and cheaply made. I sent mine back for a replacement, and even the replacement was a bit damaged. I kept it; it's a good enough lamp for the price, but know that you may have to re-thread the lampshade or iron out some dents. That said, I've had the lamp for a while and it has performed well and if I turn the dented side to the wall, it looks pretty nice too.

Here is the simple answer.....it is DECORATIVE a lamp. It has a dimmer switch. The bulb wattage is 150 W. Would I buy one of these again...no.
