How's the battery life? LED's use less power but these do have 27 bulbs drawing from 2 AA's

Battery life is good. I have not done endurance testing but they seem to be fine.

Still on the original batteries. And I use it everynight, whenever I need light, and don't want to disturb her with the room lights.

We received our units about two months ago, and we have used them quite a bit. [They really come in handy out in the country.] So far, the lights show no sign of dimming and we are still using the batteries that came with them. So far, the battery life seems very good.

So far, so good. I haven't timed them, but they seem to be doing better than my old non-led flashlights. I've found them very useful so far working on various projects in my garage where the lighting isn't the best.

I can't give you a specific time these last, but I have had excellent performance out of them. I use them at night to light up my camper and I have been out as long as two weeks and they made the trip on a single set of batteries.

Actually, I don't think you can replace the bulbs. LEDs are usually good for about 25,000 hours. That's about 20 years. What did you have in mind. I don't know about you but I'll be ready for a new technology magnifying glass way before that. Batteries will be your issue depending on how much you use it not the LEDs. You need a really small Phillips screwdriver to replace them and it takes three. The cover is real bitch to get off. You need a really small Flathead screwdriver to pry it off. Thank God the screw is held in place in the cover or you would probably loos it. A small screwdriver set & a couple of rounds of changing batteries and it's no big deal.

I've been using these several months now. Have not changed the batteries out yet on any of them. I suspect I will need to do so in the near future. I think they get dimmer over time. They don't just stop working. So perhaps I could already make them brighter by putting in new batteries. But for my purposes they are working well (I have them mounted by my stairs and hall to the bath so you can walk in the dark and lights come on as you walk by; they only come in the dark and go out after about one minute of no motion, so there isn't a lot of 'wasted' light time).

The 30,000 hours is actually projected to be 18.26 years based on average use of 3 hours/day. I am guessing the company is relatively new and has not been around for 30 plus years like Phillips or GE to offer a lifetime or 20 year warranty so they are being conservative/realistic with what they can honor. Again, just pure conjecture. I have had the bulbs for 6 months and they still work fine.

Don't know about power usage and these are smd without resistor don't buy them unless its for car,RV etc.. look elsewhere on Amazon for bulk led packages

Concerning the output of the led source. The light source is AAA battery, its light is amazing. It is extra bright. Never seen before. Try you will like it.

Not sure of your power draw. I replaced all my bulbs to led and have one line 36 fixutes and no loss of brightness.

I always go ahead and swap bulbs to LED type that are 1 or 2 watts each bulb and can have many more lights for the same wattage transformer. You then have the option of getting a lower wattage transformer to make the system even more efficient. And with a 50,000 hour life, you won't be changing bulbs anymore.

Even if it were actually "lit" by LED, the amount of power used by a single, tiny LED is NOT enough to drain the batteries in any measurable period of time. We're talking at most, a few milliwatts (thousandths of a watt).

Since this light uses an LED bulb you can expect 5 hours out of the 4 AA batteries it takes to power it. The bulb itself will give you 100,000 hours or about 10 years of use out of it just keep enough batteries on hand and you'll be fine

3 AAA batteries...no idea about the bulbs, but I wouldn't think that the bulbs will burn out anytime soon.

2 hours with all 48 LED's is about the max depending on the amount of sunlight it gets between uses, it takes a full day of full sun exposure to fully charge so anything less then that will shorten the duration

Have used it for three months already, reading for about an hour or so at bedtime and the battery is still going strong. I bought these also as gifts for three friends who are also using it every day ad they are still fine. LED lamps seem to be very energy friendly. Replacement batteries are not very expensive and one gets good deals for them.

I would say a lot more. A 40W equivalent LED bulb ranges from consuming anywhere from 5W - 7W. That's about 8x more consumed power.

Unsure of wattage or lumens. But battery is replacable and comes with spares. Bulbs are led and nonreplacable. Standard led life is 50000 hours

I don't use the bulbs that much, But I have some over several years......... They do last a long time....... but I'm not able to get you an hour count...........

I didn't measure the power used, so can't comment on that. But mine are *really* bright and I believe the claim that they are equivalent to a 225W incandescent. But they're not instantly bright - they take about 5 minutes to reach full brightness.
