  • Solid, reliable cool white emitter

    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.

    OtherThoughts:

    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).
