There is a size up and down from the one linked, they can get up to 173lpw and are extremly lightweight.

Geez, they had so much room to add a decent heatsink, but you know how corporate greed is.

From what I understand modern SMD LED luminaires rely less on heatsinks, take Cree's new Guideway series, that doesn't have much of a heatsink (though it does have way more diodes).

E-Cobra = EOL-Cobra

KarbonCobra = KrapCobra 

Just hope the KC series doesn't have plastic doors like the GCJ and GCM.

Seems promising, but I’d treat anything new Leotek offers with a grain of salt.

Hopefully Caltrans uses them, that'd be interesting.

not a bad looking design and for heatsink the top is the heatsink and that is why it is cut down compared to the gear compartment / slip fitter end

SMD LEDs are not somehow different from any other LEDs. About 70% of the power turns to heat, virtually nothing of it gets out of IR (due to no parts of the light source being at high temperatures). This heat have to be removed from the LED assembly and then from the luminaire body as a whole

The only question is, what is the actual power (the heat) vs. the surfaces area to dissipate it, regardless of whether it is shaped as visible fins or not
