My thoughts exactly, TK. It’s the closest thing to a 219B in a lightbulb form that I’ve seen.
Maukka, did you think about testing the 2400K bulb from Waveform? This opens up so many possibilities like their tape lights…
On another note, I got the CCT readings from some 2700K TCP bulbs in the vanity mirror in my bathroom, and they’re 3100K! Even my 3000K SST-20s are a warmer 3040K. Talk about out of spec.! There were some other people saying don’t mind the out of specification CCT, you’ll like it… eventually. No thanks to that. If I wanted 3000K, 3500K, and so on I would’ve bought it in the first place. Sloppy manufacturing processes should not be justified.
These will fit any lamp with an E27 socket. Their low power means that there probably isn’t a light fixture that couldn’t handle them. I use one of these Tertial workbench lights.
… oh, wait. There it is. It took me a moment, but I found it. The beam shot is just under “Measurements”, to the right of the table. It’s really easy to miss if you don’t look very closely, so I highlighted it:
Got my 2700K Waveform A19 bulb, and I am very pleased. My example is closer to 2800K, but a much better match for incandescent then my Philips A19 LED. Will probably be replacing the CFLs in my place with them.
I also got the 2400K filament light from them, but it exhibits some odd behavior. It flickers on startup, but then it seems to smooth out a perciptable amount once running for about half a minute. Do you guys have any idea what this could be?
Bit of an update with my 2400K Waveform A19. I just screwed in a new duplicate lamp, and it appears that after about a year and half this light now has some serious lumen depreciation. I want to say, generously, that this lamp probably has around 3000 hours on it. The rated L70, 70% of initial output end of life, is officially rated for 25,000 hours. It looks like I have a warranty to claim.
I just measured two of my 2400K A19’s. I used my Extech lux-meter held vertically facing the lamps at 12 inches away. The depreciated lamp measured around 230 lux while the newer light measured 560 lux. The drop in output is noticeable.
I suspect this lamp won’t even make it to 10,000 hours, and I used it in an open fixture where heat shouldn’t have been a problem. I wanted to mention, even an L70 is a somewhat poor rating. An L70 means you loose nearly 1/3 the light’s output before it gets replaced. Metal halide had comparably poor lumen maintenance, but it didn’t last as long as LED before it had to be re-lamped. T8 fluorescent was actually a lot better then LED in this regards. It has a 90–95 lumen maintenance over its long lifespan. It’s possible to intelligently design LED fixtures that compensate for lumen depreciation by having the driver gradually push more power to the chips as they age and degrade, but most consumer lights don’t do this.
Waveform Lighting got back to me fairly promptly. I wanted to mention this earlier. They sent me a replacement lamp at no cost to me. They also had me send back the defective lamp at no cost to me. The warranty and manufacturer saved me on this one.
Hi!
I wanted to buy the waveform Lightning light bulbs because I am very sensitive to flickering and light quality, and any artificial light really generate me dizziness! So i tried to buy from them, but shipping and taxes costs are tooo high.
Since I am in europe, is there any other company that produce the same type of product as waveform lightning?
