Hello,

Is there a thread about this in here?

If not, any opinion?

Looks like it has 8 dies so it will be almost impossible to get a good focus. But might be good for home lighting. These usually comes from various Chinese manufacturers so the lumen claims can be inaccurate.

Running at 12 Volts, I assume they are connected in series?

Don't bother. I don't believe the lumens claim. Plus you can get a much better(in all aspects) LED in the SSC P7 or Cree MC-E for cheaper.

Looks like a 10 watt LED to me.

You can still get more efficiency and more lumens for fewer dollars.

about 60lm/w which is pretty good for that kind of thing. so its a fake. probably in the 30-40lm/w

aim for the name brand stuff. Cree,
ssc, luxeon ect

the P7 is wat i want.

The_LED_museum has a review of a 10W warm white version of this.

One of the good things in CPF is that sometimes I don't even have to ask the question and still I get the answer!

I got this 10 watt E27 replacement about a week ago and I almost asked does anybody in CPF know what kind of led it contains:

Thanks TMorita for answering my unasked question :tinfoil: Still, I better add some layers to my tinfoil hat.. just to be on the safe side..

Here's a video review of said 10W bulb:

300 lumens? You can get a 1W CREE that does 226lm and I trust their numbers more than some brand I've never seen before.

Nah, you cannot get a 1W Cree that does 226lm.

Remember, if you drive it at 1A, its a 3.5W Cree...

I second that. We have 3W bulbs that are 3 x 1W CREE LED's that aren't 240 lumens.

For $40, you can buy two 7x bin MC-Es from cutter. Those will be higher efficiency, vastly superior packaging, and higher quality light (3500k warm white with decent CRI vs probably 7000k+ nasty blue for the brand x)

Well that depends on the bin of Cree led's and the efficiency of the optics.. 3 Q5's at 1 watt should be over 300 lumen... Crap optics would probably be the reason you are seeing so few lumen's... Are you sure it's under 240 lumen? Maybe someone could mod it with some R2 bin Cree's.. or even with MC-E's for even better efficacy

Missed the amp specification. Still 3-4W giving off more than 10 in this case.
