There are as many as two dozen manufacturers of panels now, some Do it Yourself. Look for panels that have good cooling systems as that controls how long the emitters last. Higher wattage means more heat to dissipate in the fixture. Nothing wrong with 1, 2 or 3 watt emitters as they are generally the same part, just driven with a higher current. Cree emitters in the 6 watt range are also popular. New multi-led
chips in 10-100 watt range are now out, but they should have supplemental blue spectrum support as they are rated at 6000K.
