I will try to fix the CPF links in the next 2 weeks or until I give up in frustration. Can not do that and verify with CPF down.

Today I had an ecosmart lamp sitting on a table when I bumped it and it rolled off, hitting the carpet and shattering the glass bulb. (Why does it have to be glass?)
The only upside to this is that it allows me to see the LEDs inside. There are two large round multichip LEDs with an 8mm active area. Each one has a bare silicone coating, orangeish in color, and there appears to be 6 chips in each one arranged in two rows of three each.
I plugged it into the wall and then unplugged it so I could see the individual chips as they dimmed out as the capacitor discharged, and I noticed that at least two of the individual chips were dead.
Powering it up without the globe produced an extremely floody pattern.
I might be able to mount this light inside of a globe lamp to protect it and still have a usable lamp.

I wonder what happens to the color, lumen, and the CRI, without the glass portion.
I'd definitely recycle the bulb by putting it into an enclosed globe/mushroom type fixture.
Those who say it cannot be done, should not interrupt the person doing it.

The glass was neutral density frosted, so I don't think there's much of an effect on the color of the light.

The price has gone down to $17.97 last I checked. They were 18.47 when I first bought two a month ago. I've since gotten a third one last Wednesday to add to the two I already have and have not noticed any lumens depreciation between the month-olds ones and the new one.
Anyway, despite the shape, the light produced is still somewhat directional; going "away" from the dome so I find they work best in ceiling fixtures or a ceiling fan light kit with sockets that points downward. It'll also work nicely in a drafting table or "Luxo" type desk lamp. Putting it in a table lamp results in the majority of the light shining up at the ceiling.
