While shopping for some SDHC cards for my new Canon 500D at Fry's in Oxnard CA, I browsed through the lighting section, as always. I came across a selection of fixed-lighting LED products I've never seen before, under the brand name "Nasun".
They were all $24.99 each, and come in various single-emitter and triple-emitter configurations, and are also available in "regular" lightbulb socket form (120V) and the two-pin 12V halogen formfactor. I picked up two of the 120V units, one called the "Raptor JDRE26" and the other an equivalent-but-shorter "Raptor E26".
The packaging uses a hand-written pen mark to identify the configuration of the unit. The total options are as follows, with the marked ones on mine bolded: (both of my units are the same options)
Voltage: 12V, 120V
Led/Watt: 1x1W, 1x3W, 3x1W
Colors: Red, Green, Blue, Yellow, C-White, W-White
I've been running them both in a tri-lamp for a few hours, together with the GE Par20 3-emitter warm white discussed here, while assembling this post. They show no signs of degradation so far.
The beam pattern coming out of these is just ridiculous: blue-purple hotspot in a notably yellow corona. If these are "warm white", the cool whites must be something to see
These lack the textured optics of the GE unit, but I don't think those would save the day here. At least there is no flicker or even any visible ripple from the driver.
Here's a beamshot of one Nasun, together with the GE warm white (left), on a popcorn ceiling.
(These link to images around 2300x1500 resolution, the smallest I can get out of a Canon 500D).
Now, the good news is that this thing is wide open; no loctite or potting, it's just six screws holding this thing together. This lends itself to perhaps some upgrades with newer/better emitters, including warm whites and/or something with a better beam pattern. The heat sinking seems good so far, though I've not yet measured the current, Vf or power dissipation in these unknown emitters yet.
The unit and packaging:
The face of the unit:
The top cover comes off easily with three screws. The optics look like the basic sort we know from various lights, and they come loose once the cover is off. (This is a mercy, as you can swap in your own optics, or leave the top off and add your own diffuser).
Here is the main board; note the next three screws which easily allow access to the innards.
Here's a closeup of one of the emitters. It's not a big-brand package (Cree, Seoul, Lux); anybody recognize this? And if you do, please post whether the slug is isolated Lux-style or linked to + Seoul-style, if you happen to know!
Edited to add: upon closer examination, that sure looks like the Cree die pattern in there.
The next three screws reveal the driver board, which is a compact little thing.
And here's another angle on the driver board, with the cap value for the curious:
