    Not bad, still only 9 lm a watt better than cree xpg's but if you wanted to concentrate a lot of light on one spot it could be nice. Would be a bit yellow though.

    Spec sheet I used is was an older download, the R1 bin. My bad.

    139 is probably the R5 bin. Tey make pretty good mid day supplements.

    Not sure, they have a few bright ones, not cost effective for this hobby though, and I doubt their kelvin ratings will be what we're looking for.

    Bridgelux however is making HUGE breakthroughs, high outputs with low usage and cost. I really think they'll become fav's under reefers soon.

    The problem with the bigger chips is blending the colours, so in the end it is better to get many 3w led's.

    The 3w led's is more than strong enough for it's purpose. There is quite a few reports of bleaching as well.
