The last post on this was a few years ago. In technology time, this product is near end of life :-D Actually, we have lots of filament style bulbs getting ready for production. E12 C25, E26 A19/A60 to start with. We're making 20-60V range. You'll need a NEW L2-SV to drive these as the inrush from the capacitors to allow dimming messes with the older L2-SV. If you're not sure, look for serial numbers over 4000 and the label says "L2-SV Low Side Switch"

The first batches of bulbs are through QC and shipping. Here's the brief summary and photos:

E26 A19 Filament: 20-60VDC, 5W, 100-290mA, 500lm
E26 ST64 Filament: 20-60VDC, 8W, 160-470mA, 750lm
E12 C35 Filament: 20-40VDC, 4W, 90-200mA, 300lm

3000K, 82CRI, Dimming range 20-100%.
Use L2-SV driver. Add an Amplifier if the total fixture load is over 1A.
