Yet another LED filament lamp to add to the rapidly growing pile of dismembered lamps. This one is an 8 filament version that is the first I've had that actually uses the non-glass substrate filaments. It's the metal cored ones with the cylindrical section of phosphor loaded silicone covering a perforated strip of metal with the LEDs wired in series along it.
The listing I bought this one from was:- http://www.ebay.com/itm/311226281925
The filaments are wired as two parallel clusters of four in series, giving a guestimated total of 150V at 60mA. The actual power rating of the lamp is 8W and it's spot on. Bizarrely it just doesn't seem to get very hot for such a high LED rating, but I guess there's quite a large surface area on the outside.
The circuitry in the base is a buck regulator with a small choke and an eight pin chip. This is unmarked! (Darn!)
I didn't take the lamp completely to bits, because I really like it and will probably try to graft on a standard UK bayonet cap base.
Like all the other LED lamps this thing is very bright and gives a surprisingly even illumination. If I can find some traditional tungsten lamps I'll do a light level test, but it's just really good illumination.
