It looks like Mars Hydro has upgraded their SP 250 light with the release of the SP 3000 (they still can't get away from that annoying practice though) which is a 300 watt light. The price is $399.99 US dollars.
MH say the light uses 960 Samsung LM301B and Osram 660nm LEDs. They claim a PPE of 2.74 -2.82 μmol/joule. The driver used is a Mean Well ELGC-300-H-AB. According to the drivers datasheet "de-rating may be needed under low input voltages" so anyone using 180VAC or under will only be able to use 85% of the drivers wattage potential.
Their sales page also mentions UVA 390-410nm and IR 730-740nm (please call it far red, darn it!), but there's no mention which diodes if any were used for those wavelengths. The MH site also says "More warm white and red chips have been added", so hopefully this light does a better job flowering plants than some of their previous offerings did.
