I received the package a few weeks ago, but did not get to this write-up before.
An unpleasant surprise was that I had to pay customs, so another 18 euro's was lost :-( All in all I would not have ordered two bulbs and a bag of 5mm leds if the shipping+customs were to be 46 dollars.
The packaging was very well done:
and this was inside:
I did not have more than a first look on the 5700K 97CRI GU10 spot, but here are some findings on the E27 4000K 95CRI remote phosfor bulb:
It is smaller than I thought, quite elegant:
The bulb does not show any flickering when photographed, unlike the IKEA led-bulb that was in the floorlamp before:
IKEA: Yuji remote phosfor:
The white ceramic base of the bulb does get too hot to touch over time, but not so much that I get worried, many ledbulbs have that (including the above IKEA bulb). In my integrating sphere I measure 460 (djozz-)lumen after the bulb has warmed up for 10 minutes, which is in line with the factory-claimed 420 lumen.
I first put the bulb in the large floor lamp that is next to the couch. It gave a very good colour reproduction and the colour temp looked to be 4000K indeed, but it still felt weird. I then realised that the light was too dim for 4000K: light of that colour temperature (sun) is always very bright, if too dim it looks unnatural. The moment my girlfriend switched on the light later that day, she noticed the new type of light, said it was like hospital lighting and that the bulb had to go :bigsmile:
So it had to go into something smaller. I have a small worklamp for hobbying, and in there this bulb is just perfect: a good bright 4000K 95+ CRI soft flood, I'm really happy with that :-) :-)
So how are the 3200K 90 CRI 5mm leds? They are wonderful too. I have not measured the output yet, but the warm colour and quality light is evident. I put nine of these in such a typical 9x5mm 3xAA cheapo flashlight and it became my bedside flashlight instantly.
The die projected on the wall with a lens, and a stereo image of the led:
Conclusions from this one order:
-For now I'm fan of Yuji leds, thusfar they look like quality products that perform to the specs, products that are hard to find elsewhere.
-The pricing seems reasonable
-Buying from their store is easy (Paypal)
-The number of products is limited and even then not everything is in stock.
-Packaging is good, shipping was fast (DHL, one week if I remember correctly).
-Shipping and customs are very expensive if only a few bulbs are bought, like I did. For larger orders it is no problem of course.
