Just got this in the mail yesterday..

Got this yesterday in the mail. I ordered it and it got here in 3 days. It's pretty bright and seems like more than 600 lumens. Downward light is not as bad as it might look from the shape. It feels really solid like their other products. The best is the color temperature. It's just right, not too yellow, not too white. It's slightly longer than this 60w in the picture but it fits all the fixtures in my house fine so far. Anyone willing to do a teardown?

What is the color temp?

I have some that look real similiar, and although very bright the base get's too hot to touch after awhile.

Curious how your's run.

How much did it cost and do they do bayonett fittings for the UK ?

it has been running fine. a rule of thumb for led head sinks is that you should be able to put your hand on it for just about 1 second and not get burned per se. in other words it should not be too hot NOR too cool. the color temp is 2700k like deadr linked. i've put it in a standard table lamp and the lamp has its own dimmer which it works without a hitch on.

i'm not sure if they have the bayonet type bases but you can email them and ask. does not look like they website says anything about it. they respond pretty fast when i emailed several times.

it cost 34.90 plus 8.25% tax and 8 dollars shippiung but next time im ordering more so that shipping is free (over 100 i think or 150...cant remember).

How has this bulb been working out for you? These might be my second choice if I can't find the ones I want. The only problem is the light output is about 200lms lower and the color temp is slightly warmer. BTW, I saw a place online selling them for $25 each with free shipping.

Not too hot nor too cool?
How exactly does that rule work?

I can envision cases where the LED could get cooked regardless of what the heatsink temperature is. With an inadequate heatsink, you'll always cook the LED. The only thing that the heatsink temperature will indicate is what the thermal resistance is between the LED and the heatsink.

I hope these lights do have adequate heatsinks. If they are too hot to touch for more than a second, then I have some question about their longevity. It would be a shame if LED lights got a bad reputation due to the short lifetime of the LEDs or drive electronics.

9W third from left, 12w right.


The bulbs with the LEDs on heatsink facing up (the OP's bulb, the Philips 9W and the Zetalux are directional. Notice the lamp base is lit by the incandescent but not by the LED.

The Philips 12W with the LEDs facing sideways is better at all around light. (Don't have a beam shot, waiting for my Lighting science 60W equivalent neutral.)

The A bulb has been working great so far. I picked up 5 more for around the house and one porch light. I got mine for $25 on Amazon. Pretty good deal. Have not gotten around to taking more pictures but I will try to tonight.

My only complaint right now is that if you have a cheap IKEA gooseneck floorlamp, the weight of the bulb pulls the neck downward. I have another goose neck lamp that is stiffer and it holds the bulb fine though.

they have a picture of the illumination pattern but its not very clear.http://www.amazon.com/Tuwago-Dimmabl...8816973&sr=8-1
