One practical use for the 3d printer: a completely printed light fixture. The big cube is 25x25x25 cm big. It could have been smaller. Took around 22 hours to complete, made from two pieces glued together. PETG.
Good thing you used an LED bulb. I wouldn’t trust any 3D print near an incandescent.
@_Spice people are still using incandescent bulbs?
@Thomas_Sanladerer States-side, sadly they are. I’m getting a steady conversion rate (Thanks mainly to LEDvance dropping their prices considerably), but I still get an unnerving amount of people wanting incandescents. I’ve even had one person go as far as say they read that LED’s “give off harmful radiation that causes cancer.” There are some cases where our guests couldn’t use LED’s. For some reason, the LED bulbs we sell do cause some radio interference that’s enough to mess with wireless garage door openers and some AM/FM radios (I haven’t tested it myself, but the garage door one has come up enough times that it’s an actual problem).
well they invented CFL long time back but i still don’t understand the obsession with the yellow bulb… some just want the warm felling !!!
@ekaggrat_singh_kalsi Warm/soft white is actually more desirable for living spaces because it’s a lot more gentle on the eyes (though, people still tend to gravitate to daylight and the new bright/cool white LED’s for better clarity). Also, I strongly encourage people to go away from CFL’s, due to their mercury content and most often lifetime inefficiency depending on how the ballasts in them are made (usually I hear about 1 year before they go bad).
@Thomas_Sanladerer Maybe. They are not illegal in the USA yet. Meanwhile, some people think LED bulbs are expensive here. Not really. It is around $0.50 - $1 a bulb.
Some use incandescent bulbs for puppy lamps since they put out so much heat, but not enough to overheat the puppies. I think one of the sellers transitioned to LED without labeling it as such and a friend of mine had a puppy die from getting too cold. That or they fixed the filament formula for their bulb to not burn out. There is some myth online about the bulb makers joining together and deciding to make the bulbs less efficient and burn out quickly. It would be a sad thing for this world if that happened. I wouldn’t doubt it if it did happen though.
@NathanielStenzel It’s actually kind of funny. At the store I work at we’re steadily getting rid of CFL’s in favour of LED’s, but incandescents still hold a good 8 feet of our bulb section. Also I will say that, although you can get LED’s for about $1 or less, they’re often cheaply made and burn out quickly (some of the ones we tested in our department lasted 6 months on an approx 16 hour a day use). Compared to LEDvance (going under the Osram Sylvania name) and Feit Electric, who’s bulbs cost between $1.25 - $5 a bulb, it’s no real contest. They even give you pretty good warranties at that price (3 year on LEDvance, 2 years on Feit).
@_Spice It makes me think that the LED bulb makers are betting on nobody complaining about the bulb going out. I have noticed that inconsistent power due to perhaps a loose wire on an outlet will cause LED bulbs to fail quickly. Perhaps if bulb makers added some sort of voltage spike protection, it may fix the issue. 3 year warranty is not all that uncommon on LED bulbs. I think it might be the bare minimum even. I am sure some of my LED bulbs lasted over 5 years.
@NathanielStenzel in our test LEDvance has the highest life expectancy of over 7 years off of 16 hours a day. I did have one fail a few months ago, but that’s one out of about 20. But they aren’t the only good bulbs. Feit is the only LED manufacturer we carry that has bulbs designed for enclosed fixtures, thanks to their better heat dissipation.
@_Spice are you biased?
I try not to be, but the results we’ve had show every off brand bulb (which mind you never stays as a permanent product save for one brand so far) hasn’t come close to the performance to price that the name brand bulbs we carry. Even Westinghouse LED bulbs have a terrible track record and actually hold a worse life than the generic wholesale bulbs we get.
we had the very same led filament light bulb, the filament is made of randomly mashed leds that are covered in orange uv pigment, there is a small ac to ac circuit that passes the alternating current over that ‘strips’ - so it changes the polarity of those strips rapidly, to light up leds that are in certain positions (mostly half of them) then it switched the polarity again and lights up the other half (more or less) unfortunately if any of those led are cheap quality or damaged during manufacturing process that will put higher current over the others, that will cause them to short their lives until more dies and then it will increase and kill even more until the ‘strip’ will fail to conduct at all, that is what happened with mine. now when I turn it on its like a disco with sound effects. I have another LED that is constructed of properly made ac to dc and array of 3 individually powered leds, this light bulb is still operational. I would recommend to buy something that have heatsink and less but more powerful LEDs , none of this ;comb; or ‘filament’ types that are made of randomly mashed leds that are basically frankenstein experiments ( connected straight to ac )
In UK and Poland there is a lot of people buying filament light bulbs, and they also leave them overnight, and the most favorite is 100W one. I observed majority of old people doing it , at stores they just do not understand what LED mean or what is is, otherwise they complain that LED ones are not bright enough. Basically I would say people merely discovered and poorly understood what cfl is, since a lot of shops are still selling halogen filament as “energy saving” … the only LEDs I can observe on large scale are street lights and signs implemented by city councils
You can get a 40W (actual watts used) LED bulb that lights up a garage like it had no roof on a sunny day. It is as powerful as I think it was 3 of the 60W incandescent bulbs.
