I donāt think frosting or even white powder on the inside costs a lot of Lumen.
Maybe you know / remember the Philips Argenta Tungsten bulbs of the past?
Do not buy on aliexpress led bulb kits! Buy on taobao!
There is one big problem with led bulb kits from aliexpress seller what I find. Plastic thing (where E27 carving). This plastic will die and crumble (turn into dust, will cracked) after about 6 month =( That was the reason why I bought 3d printer. I will do this part from poliuretan plastic. From taobao sellers it is still alive =) But I do not want to repeating this situation. It must work 20-35 years in my lamps!
Does anyone plan on reviewing high CRI LED tubes? The kind you replace fluorescent bulbs with. I have two 48ā fixtures in my living room and would like to get some high CRI tubes to put in them. Or maybe i should just change the fixtures?
The fins on these heatsinks are too tight. Convection cooling works better with wider spacing between finsā¦ but this is taobao, so they probably go by āmore fins betterā
Iāve made a pendant light.
This is a lampshade from the store, 4 ExpertColor 3000K spots, some accessories, and a round piece of acrylic diffuser with a patterned ābumpyā side. I frosted the other side. It works very well and makes a beautiful soft diffused light. Sure it is a bit weird to use GU10 spots to make what is basically a big softbox, butā¦ thatās what I had on hand and I really like the tone from these. Theyāre perfect to light the dining table. I think Iām going to make another with Sunlike LEDs.
no =)
this is the winner in low CCT (2700-2800k) :face_with_monocle:
0.5$ per 1pcs :money_mouth_face:
CRI:99-100 CQS:99-100
But I made glass mated by myself
If add diode (or low voltage) - it will be more low CCT
Now I can only try to use most white cover for led bulb (white milk from Chinese language). But it will be 2500-2600k with 2700k led.
I already contact with SmartEcoLightning co (SOL manufacturer), they say that 2000pcs if I want 2300k. I have no so much money for this =(
They have awesome web-site, but shit product for 20$. I mean that they almost ordinary filament bub is shit. It will work about 1 year, because there is no any cooling system for crystals.
