How about using lights that actually use the same wattage? Rather than a CFL that only uses 65watts vs a 150watt HPS. That test was flawed because they used a 250watt EQUIVALENT CFL. Peppers flower under 10000K lights just like they do under 3000k lights. Much more important are the relative humidity, watering schedule and what you are feeding them.
