My gratitude to those who are willing and able to help others (in whatever way you can)! Being human is more than just existing for yourself. Smile

Advertised as bouncy bulbs: http://inhabitat.com/worlds-first-unbreakable-led-light-bulb-can-be-drop...

“and has a takeback program to keep it out of landfills….
… the Durabulb boasts omni-directional amber light and lasts up to 10,000 hours.
Lighting Science also plans to offer a take-back program where consumers will be able
to trade in the Durabulb for a 50-percent-off coupon after its three-year warranty ends.”

I wonder what “amber” means. Lighting Science used to make “turtle safe” amber LEDs, so they ought to know.

Looks like these ‘filament’ bulbs are all called “amber” — glass enclosure of a LED strip.

Huh, the Home Depot/LSC “durabulb” looks to have the square light source inside.
The “AliExpreess linked earlier in thee thread (“COB) to have emitters on a circular board — anyone know more? THe illustration looks like light is emitted on both sides of the board (the side of the bulb toward the screw threads isn’t shaded)

I wonder when we’ll be able to buy ceilings that light up ….

^ Not a real COB (or COG), but just 4 of those LED filaments stuck on a piece of glass.

It is 4 of the filaments stuck on a thick piece of glass. Then they used some sort of flexible glue (goop) to stick that to the flexable vinyl frame (globe). All of this is done to cushion the actual filaments from shock. Hence the term “rough service” bulb.

The filaments are COG, chip on glass. So because these filaments are glued onto a slab of glass they perhaps could be called
COG on glass, or COG-OG
chip on glass, on glass. Big Smile

Actually the chips are on something (?) inside those filaments.
So it’s a FOG light.. (filament on glass) Silly

Got a bucket-O-bulbs today, 10 for the $9.90
Used 9 so far, need to get another Tub.
Nice light. Used 3 sets of 3, over 2 bathroon sinks and a cieling fan. One left. After a few minutes they are pulling about 5.5W. Nice color and really surprised how well the light gets dispersed in all direction.

Definitely need more.
