I just picked up this set

https://www.amazon.com/Changing-B..._m_rp_1_sc

Costs a bit more for a lower wattage rating, but I like that it's app based instead of having to keep track of another remote.

The app is pretty basic and not the best ux/ui, but I have it set on a schedule, so it's a set it and forget it for me.

Do these use the same amount of energy as the 150 W equivalent incandescent bulbs? How long is the cord?
The other thing that keeps me from buying more of these types of lights is whether or how bad they are for the eyes. Because they have found that a lot of LEDs , Probably most, emit The kind of blue and green spectrum that damages eyes, in the long term at least. I think this is even true if the visible colors to us are in the warm colors. I think there are some that don't give out those harmful spectrums but I don't know which. the more exposure you have to the bad kind Spectrum, especially at nights, The more It accelerates getting problems later like macular degeneration. And in the short term it messes with your circadian rhythm, melatonin production, sleep…
The whole blue/green eye damage thing is wildly overblown. Really it's essentially an urban myth, and those blue blocker glasses you bought? Surprise, they barely block any actual blue light. If the damage was real as the hysterical internet articles say, we would have all been blinded years ago by just being outside for a few minutes a day in the sun.

For an actually credible take on the story, try this from the Harvard school of public health, or just Google "blue light eye damage myth", and this will be near the top of the list...

IP66 is a little more resistant to splashes. Ideally you want this to be atleast IP67 resistant

No color light that is visible is harmful for eyes. It's VIBGYOR of the electro magnetic spectrum that human eyes than see. The non visible ones are harmful like IR UV XRAY Gamma etc. Only other light that can make you blind is laser but that's not the kind of LED we are talking about here. The blue light is totally a myth. Screens don't emit any special blue light that blinds you in the long run.

Please take some time to do some scholarly research and actually understand the headlines that you read before spreading misinformation. While blue light from phones/LED lights has the CAPABILITY to disrupt the circadian rhythm of certain people IF viewed for extended periods at the wrong time, it will not cause macular degeneration. Think about it: [Depending on the season of the year and time of day] You would typically get more 'dangerous' blue light from a half-hour walk outside than staring at a screen or sitting under an LED floodlight for 5-8h, and I have yet to find a doctor that would stop someone from taking a daily walk outside to prevent macular degeneration.

There are XX watt incandescent bulbs, or XX 'watt equivalent' LED lights. XX watt equivalent incandescent bulbs is a nonsensical statement, since incandescent bulbs are what is being comparing to in the first place. People generally associated incandescent bulbs light output (lumens) with power rating (wattage) IE, someone would understand how bright a 60W bulb is, but not what an output of 800 lumens looks like. When the industry shifted from incandescent bulbs to CFLs and eventually LEDs, they used 'equivalent wattage' numbers to help people bridge the gap and understand that a 9W LED had the 'equivalent' light output of a 60W incandescent, at less than 1/6th the power consumption. The particular light in this post is listed as a 15W LED with a 150W equivalent light output. If the specs are true, I would expect a 15W power consumption, and ~2500 lumen output (typical output of a 150W incandescent). Granted at that point, my common sense would step in, and knowing this is only a 15W light, I would estimate somewhere closer to 1500 lumen actual output, maybe even lower.

I'd rather pay more and have bluetooth control or wireless however it works instead of direct line of sight.

I came in here looking for discussion on how bright (or dim) these things actually are, not walls of text talking about eye damage. Are people buying these thinking they're VR headsets or something? who the hell stares into flood lights? Why is this a discussion?

Anyway, anyone have these? What kind of actual light output do you get?

I would like to have time to do more research on it, but I have done absolutely no research on it. I was trying to invite People who might know something about the subject to comment. I just heard a few reports A while back, from good sources about it, and was trying to paraphrase what I think they were saying. Wasn't trying to 'spread misinformation' but Bring up the subject (I said Things like: I think they are saying…).
I guess my point was just about bringing up claims without doing any research. Your original statement was
Quote :

No preface of "I think..." just a statement of what you tried to present as fact. Then you went on to make a bunch of completely unfounded 'I think...' claims, with no scientific basis, and no supporting information. Hence my earlier 'misinformation' reference.
Quote from Inbox :
I didn't say any and all blue light exposure is harmful… of course not… It's about the EXCess amounts of blue lights, over and above what people would normally get If they lived as People have for most of human history.
This was my "Think about it..." point in the first post. Your eyes would get MORE exposure to blue light spending all day outside than staring at a screen or sitting under an LED lamp. Assuming ~110,000 lux output from the sun and this LED light casting an optimistic 2500 lumens over a 10'x10' area, some quick back-of-the-napkin math would give you a ~400x HIGHER illuminance value outside. Even assuming ~1,000 lux for the sun on an overcast day, you're still probably going to have ~5x fold increase in illuminance comparing the sun to this light.
Quote from Inbox :
And exposure at unnatural hours..."Think about it", we are talking about lamps, lamps that you mostly use at night, so you're getting excess blue lights& at unnatural hours.
This was the part I agreed with. A lot of blue light at the wrong time of day can delay melatonin output, and mess with your sleep cycle, but studies have yet to find any evidence that it actually causes damage to your eyes.
Quote from Inbox :
I mean are they totally idiots at Apple computers, since they made the changes to the devices lighting? You don't think they looked at the research?
The research that prompted Apple and other device/OS manufacturers to add the "Night Shift" / "Night Light" features with reduced blue output had to do with sleep studies, not eye damage.
Quote from Inbox :
Don't try to take my words in the stupidest possible way and then create an argument about it.I didn't hear/Recall a lot of details, but I think they did say it is likely A big risk factor for things like macular degeneration. Most doctors are not necessarily up-to-date on the latest research. I don't remember how certain people are about this yet, but bright LEDs are Often Harsh and unpleasant.
I'm not taking your words in the stupidest way. Maybe you misunderstood an article. Maybe you misread it, or remember it differently, but I have yet to see any scholarly article linking macular degeneration and blue light at a level consistent with a normal household/work/school setting. Maybe harsh/unpleasant, but not physically damaging to your eyes. The American Macular Degeneration Foundation [macular.org] has this to say about blue light from electronic devices:
Quote :
AMDF's position is that people should definitely wear UV protective sunglasses for sun exposure, but right now there isn't much evidence to support wearing blue light blocking lenses for everyday electronics use. Little evidence currently exists to suggest either that this level of blue light exposure is damaging to the eye or that the current glasses on the market offer any significant protection.
As for your comment about myopia...
Quote from Inbox :
I think it's akin to another report that I barely remember the details to saying that they now know the cause of most myopia.. something like not getting enough of the right kind of light exposure in childhood as people normally did because they Spent most of the time outdoors, unlike a lot of kids these days. And probably also unnatural eyeball usage. To paraphrase sloppily, as usual.
All of the child myopia articles I have read linked screen usage and forcing your eyes to focus closely for long periods of time, not specifically blue light, to increased myopia rates.
