Probably not advisable, leaving a high intensity light on all day would throw off your circadian rhythm.

I don't think that would give you the light that you are looking for. It's very bright but you need to be sitting within 12 inches of the light to get any affect. You would probably want to get a bigger light that was meant for lighting a larger area. This is a great light for light therapy, but not for lighting a whole room. I also think the light bulbs wouldn't last very long in that situation.

Never ever all day. See prior answer. Also see reviews about lightbulbs. They are very good. Remember..........NEVER ALL DAY, FOLLOW MANUFACTURER'S DIRECTIONS PLEASE.

The bulbs are rated for several thousand hours, but do lose intensity over their life span. The lamp is not designed to broadcast light over a large area, such as a whole room. Impact on your circadian rhythm decreases as you move further away from the light source and the LUX level drops significantly as the distance increases, e.g. 10,000 LUX at 12" would drop to about 2,500 LUX at 24", and that is based on the lamp head being directed as shown in the upright image. You could lower the lamp head to direct the light downward to lessen the intensity or you could use the task setting on the lamp which turns on only one of the two bulbs.

Hi Nancy,Well I think that 2 lights would be sufficient for your needs. I have 2 of them, one on each side of my Storage Shed door and they light that up very well. Just make sure they are where they get sunlight during the day and you will have light at night. Try to position them at that point so they will get all the sunlight you can muster.Good luck and Amazon is where I got mine and they have been great.JB

It is not supposed to light up during the day. We had that same issues a few days, but most days the bulb did turn off. Our main problem is that it would turn on for no reason some nights...and then never turn off. But if there is one thing I am certain of....it shouldn't light during the day.

I have 7 of these in operation now (plus 4 more to be installed) and with normal AZ weather they all remain lit until the rising sun turns them off. Even with an entire day of grey skies they are on past bedtime. I recently bought one of the one watt models (SP2) and was very surprised to see it shine brightly for 12+ hours right out of the box! If it can run that long after possibly weeks in a box I have no worries about it's charging/storage ability in normal use.

I use the lamp all the time as a reading lamp. It is virtually on all day & night. I've had it for over a year & it hasn't gone out yet.

Seems to me A19 bulbs are incandescent bulbs. As I remember they run hot. So hot that if you have to change one I always had to let the bulb cool down. I use a CFL bulb and runs barely warm. I have been using the same lamp as yours maybe close to a year and never a problem. Try using a CFL or LED 60W bulb (less energy use and they last a long long time) and I think you will be happy. Sometimes my lamp will stay on from dusk to dawn. The lamp is a great quality lamp and I wouldn't hesitate buying from Boston Harbor. Just a thought!!!!!

I have used 50-250 trilight bulbs in a similar lamp with no problem. I do not have a bulb that size at the moment to try in new lamp but I see no reason why you could not use one. I checked my lamp and there is no specifications to the maximum wattage. There is lots of room for air flow and the shade is open. I see no problem at all.

Hi, Donald. The bulb is bright and is very energy efficient, however the life is shorter than most standard candelabra based bulbs. It says the life is supposed to be 3000 hours . . . I have purchased three and of the three, two of them lasted less than 500 hours. Pretty pathetic for a bulb in this price range. The electricity saved does not balance the cost of the bulb. In my experience, the lamp is a poor choice.

You have to follow the instruction on which direction to place the panel, I think it said southwest. If you do that and it's sunny all day, then you should have light through the night. But if it's cloudy or it rained the whole day, the light will only stay on for a short time. In most part, this light is pretty good. I have 4 of these lights around my house.

I've been testing mine since this question came in, 4 hours continuous use of the 3 LEDs since I turned it on (i.e. unplugged it from power) earlier today to do a test. It's still "on" and still quite bright after that time. I rely on these (I have 2 of them in the house) to come on automatically in an outage, and help me find my way to my stash of brighter flashlights and other emergency supplies. They do cast plenty of light for that and other basic purposes. If you REALLY don't want to be in the dark though, consider having additional sources of battery-powered light in your emergency kit. As we've all learned recently, it may be days rather than hours that you'll want some light.

The instructions say not to use it more than once a day. It is probably because the lights may harm your eyes more than they would harm your skin though. Using once daily in the am worked over the course of a week with noticeable improvement seen in two days for us.

I would strongly suggest the bulb strength advised. The notice is there for a reason. Unfortunately, I find that most lamps, pendants etc. have insufficient lighting for my 40+ old eyes!

you should be able to. I leave identical bulbs outside and on 24 hrs per day everyday. They last summer and winter outdoors for years.

Hi - I think it will depend on what other lights you are using. The light is on the white side of the spectrum and noticably more white than traditional incandescents. It is not as harsh as the ones with a really white light. I have been using one bulb 24 hrs a day this winter in a room we use occasionally. It is fine, but I intend to replace it with a softer light this spring when I move the plants outdoors. I hope this helps.

One of the first things I noticed was that light's focus seemed to be for a small area. I did a little rearranging in my "house" garden and now it is focused on some small plants and (I think) they are responding. For your palm it might be a case of only the closer areas really benefiting from the light. But I have been running my lamp 24/7 since I got it. Maybe a little constant light would be a boast for your plant but without trying, I can't say.

I've used mine for 6 straight months (24 hrs/day) last year wintering plants here in Alaska. This year it's been on 16 hours a day using a timer since October. I use one of those flexible table lights you could by at any store. I would look at some of the suggestions mentioned in earlier comments for possible light failure.

Hello live in Louisiana which is a wet climate although not at all like the NW. No problem so far and have one of mine on a tree about 10ft up and provides good light down on my shop lock. Also the tree is full and thought it might be too shady for the solar panel on the light but it lights up every night.
