Just saw in wal-mart that they had 100 and 200 watt bulbs that are 2700k way cheaper than the bulb stores online. the 100 watter was 8 something and the 200 watter was like 12. looking online these same bulbs were like 30-40 bucks. so if you are on a budget or just want to amp up your wattage using cfls, this would be a good way to go with a few splitters. hope this helps some money conscious minds, lol
