Even with a price reduction from economies of scale, I think they’d be a lot more expensive than the average person is willing to spend on a light bulb.
I remember SunLike speaking of these bulbs being designed to last a very long time. If my memory serves me well he spoke of 20 years.
Now I’m convinced that I want to have some but expected durability is a big factor in the discussion. If I can expect 5 years, I’d buy a few for fun uses. If I can expect much more I’d buy a larger volume.
Can someone independent who has a good idea of electronics share their thoughts on the topic?
I have three or four LED 110v household bulbs that have died, clearly a driver component (multiple emitters visible, none damaged)
All of them are glued shut.
My brother gave me a small hair trimmer whose batteries were dead recently, it was refusing to work with a blinking red light. You could make it work by first plugging it to the power supply, turning it on and then disconnecting the supply's cable, but refused to work by itself on batteries. Its electronics raised the end of life flag, this means even if I had replaced its cells the thing wouldn't have worked.
On the other hand, I have a cheap hair trimmer which I overhauled with li-ion cells years ago, tuning its charging voltage for everlasting life. It also is noticeably more powerful than stock.
So, what are we paying for and why are we paying for?
People should completely stop buying carelessly, stopping this insanity.
I prefer to make good stuff. Anything which purposely reduces your vibration or that of what you do, is a disservice. As a consequence of looking at self interest beyond the highest good, it is skewed and leads to crash. Like being on drugs.
Like many of you, searching for a high performing 95+ CRI 95+ R9 LED bulb under $25 US - very difficult, it seems. The performance of even 90 CRI bulbs isn’t good enough for my eyes, colors washed out and ashen - yuck.
I have MASTER LED ExpertColor LED ExpertColor 5.5-50W GU10 927 36D 871869670767800
in warm white
CRI (Nom.) 97
they are very nice also the tint is good but I can not test things like CRI or R9
Anyone measured flicker on Philips LEDspot ExpertColor GU10 ?
On Amazon I see few reviews about flicker,_
“However, there is a very small amount of flicker both at full brightness and when dimmed,
which is disappointing as some cheaper LEDs don’t flicker at all. ”_
and “Actually nice warm light with good color rendering, but: It flickers!
It is impossible to take photos with a digital camera (Lumix G5) or even with a mobile phone, because everything looks striped. ”
Can you measure temp. of these lamps (thermometer, thermal imager ) after 1 hour work?
How much flicker on full power or when it’s dimmed ?
