Solid, reliable cool white emitter – 30W 2400LM LED Emitter Metal Plate - White (16V~18V) Reviews

Involvement:General (knows how to use it) - Ownership:more than 1 month

Pros:
* Much easier to use (wiring and heatsinking) than 30 x 1W LED, 10 x 3W LED, or such.
* DX now has drivers to support, such as sku.42746.
* DX has a couple of reflectors to support, such as sku.39963.
* Emitters are spaced out for good heat distribution to the plate.
Cons:
* I had at least one string of LEDs that had a "dud" (see pictures).
* Value is no longer very good compared to other options that are becoming available, such as sku.66382.
Other:
I used 3 of these in series, with a dimmable driver (purchased elsewhere). I had to dim down to ~700mA (32W total) to get a similar amount of usable light as the previous 80W fluorescent fixture.
Bottomline:
My experience with this type of emitter has been good overall. As noted, there are now better options in terms of value ($/Watt).
