LEDVANCE (Osram) Classic Superior 97% CRI 40, 60 & 100w Retrofits 1 x 4.2w 470lm Classic A40, 1 x 7.2w 806lm Classic A60 and 1 x 13.8w 1521w Classic A100 coated LED filament GLS lamps. All with very high colour rendering indexes of 97% while still achieving a reasonable 111 lm/w! Companies like Philips ect, make more efficient LED filament retrofit lamps but these are better IMO as the colour is far more realistic and when lit, you'd be very hard pressed indeed to determine that it wasn't in fact a proper incandescent lamp! They also make these with clear outer envelopes but I'm not a fan of clear LED filament lamps. I was never a fan of clear incandescent either to be honest!

Been using these recently for jobs. Seem reasonable. I've been put off Philips somewhat as I've found their LED tubes struggle to do 2 yrs, whereas the cheap generic ones from a local wholesalers are at 7 yrs (500+ install) and so far I've replaced 2...

This is what LED retrofits should have been like right from the start. Not the crappy and often dangerous COB lamps, or those traditional shaped ones that used a planar array of SMT chips where only the half of the lamp lit up. The "filament" style were getting there but the early ones I tried seemed to have a sickly light like old halophosphor fluorescent. These are not as efficient as some from the likes of Philips but that's a price I'd pay for a diffused lamp with very high CRI. As far as I am concerned, there is now no reason *not* to use these over CFL and incandescent despite personal feelings towards the tech. Let's hope they last as long as they claim!

I'll have to get some of these to see what they are like! As you said the early ones had a halophosphor fluorescent colour to them, and looked rather like a /29 tube, which isn't really a good GLS replacement. Even the later ones with an 80's CRI still looked a bit yellowish compared to CFL, so it would be interesting to see how these compare with such high 90's CRI.
A good test would be to see how these look inside an opal glass fitting/bulkhead, in my experience the opal covers really looks quite different with the rich, warm light of a GLS compared with the more artificial light of a CFL or LED.

I like these lamps. I have 3 of them, earlier than yours as my ones are Osram branded rather than having LEDVANCE on them
