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 asAC expecially when 230VAC.
Pros: - Great! I am really positively surprised as it is indeed what I have wished to get- Very small, fits into the smallest DIY projects- Doesn't get very hot. This is very important for me
Cons: - I think the price increased. I would prefer a cheaper price.- To repeat the question: Why is the colour code not black/red? The batch I have received is white/red.- Two of the three drivers have lopsided soldered transformers. This is just a cosmetical issue as the soldering is in general very good.- The current could be higher: See Section Bottmline.
Other Thoughts: @DX: Please reduce price for the Bulk Rate of this item. If someone is needing one of these the price is ok, but if you need 10 of them because the current is not very high, than the price is not attractive.
Bottomline: I can recommend these with my one week experience with this item. Here are the spezifications of the drivers I received in April 2009:Environment: 240V AC, 1x CREE XR-E P4 (SKU3475)Measured Voltage: 3.4VMeasured Current: 650mA
Pros: It is very small, which means you can stuff it into any equipment or light fixture.
Cons: the presoldered wires are thin and the solder joints for the wires need redoing because otherwise they will just rip off
Other Thoughts: I used it for my solder fume extractor fan along with a edison optio emiter and it works a dream, that is after I resoldered new heaver duty wires on Im on 230v and it works well. Also when you turn it off, the light goes off, and then the capacitor disscharges through the light
Bottomline: I will get lots more when I need them!
Pros: - Very small- Simple to use- connections are labeled on the PCB- Stable 655mA output
Cons: - The LED wires should be black and white/red instead of white and light pink.- The diode gets very hot, too hot to touch.- preinstalled wires are very thin and surface mount only.
Other Thoughts: I tested this with a Cree Q5 and SSC p4 on 110AC with good results. Be sure to use a big enough heatsink; a modern northbridge heatsink works nicely as does a large RAM sink. I ripped an AC cord with switch out of an old lamp and used the top of a tap light for a diffuser. Both were from the thrift shop totaling $3.
Bottomline: It uses a little over 2 watts of power but makes for one hell of a night-light.
