Pros: Appears to be reliable, after about 1500 hours of flawless operation.
Small form factor fits sku 13741 nicely.
Perfect current for a 3.5 Watt LED without running it on its maximum.
Doesn't seem to run hot. LED and driver in sku 13741 don't heat it up to more than being warm to the touch. Below 40 C, I measured once, but forgot the exact temperature, as being not too relevant, because cool enough.
Silent operation - no humming, cheeping, chirping or whistling.
Cons: They don't come for bargain prices in lots of 5 or 10
Other Thoughts: I still haven't measured the ratio between input power and output power, and as such, I can't really say a lot about how much sense it makes to use this device for energy saving purposes.
Bottomline: Good component for building your own LED bulbs. just add sku.13741 and a 21 mm star LED, preferably in warm tint.
small and does its job

Pros: -its really small, like mentioned a couple of times before me.
-Gives off almost no heat. Gets lukewarm after a couple of minutes
-powers a single 3 watt LED just fine. Tested it with a Cree Q2
Cons: -Gives off a nasty buzz when powered but not in use.
-too small to pick up when in use. you will be zapped.
- Pre-soldered wires are a little too short for most people i think. Get replacements ready when you order this.
Other Thoughts:
Bottomline: Perfect for most DIY projects if you need a good, small driver for a 3 watt LED. I wish there would be a version with a 1 amp output, but this one is the closest to that that i can find.
Works well even with 2 leds!

Pros: * Makes no noticiable heat
* Small
* Works even with two leds (5mm)
* Works at 220V 60Hz
Cons: * Price (i think it could cost less)
* Very dangerous if touch the AC area
Other Thoughts: * With one led it will blink it
* Two leds, it blinks less, but blinks
I am using them to illuminate a sewing machine (the area of sewing) and it works well with 4 5mm leds.
I like it! Best if
Bottomline: Very nice to have but it isnt cheap. I will buy again to small DIY projects, but the price holds me from buying a lot of units. Maybe bulk price isnt so attractive on this item.
LED's make light.

Pros: the smallest and finest 3 watt leddriver for AC use I've ever seen.
Perfect to build your own ledlight for home use.
Galvanic isolation for 230 VAC, the led can safely touched when in use.
Because the led itselve can become very hot , the danger of burning your fingers when touching the led still exists.
The driver itselve generates almost no heat.
Cons: none , really.
Other Thoughts: by combinating several drivers and more leds you can make your lightsource as powerful as desired.
The almost unmeasurable energy thid unit draws, expecially when combined with high efficiency 3 Watt CREE leds, you can save a lot of money compaired with other lightsources.
Use bulkrate and buy enough in one time.
Bottomline: Untill this moment, this driver is the best /cheapest on the market.
Watch out, the primary side of the driver/ water is as dangerous as
AC expecially when 230VAC.
