I've also ran every bulb on the market and have seen amazing things since introducing solis tek 4k MH bulbs for flower with their ballast. I've been playing with the double ended bulbs by Phillips and
ushio 1000w with the e-papillon ballast but recently been learning about their d-papillon Very interesting stuff Phillips is doing these days. Here is a little info I found on them
The Philips GreenPower and Daylight grow lamps are full spectrum lamps that irradiate the farred and UV spectrum.
The D-Papillon Fixture consists of an Ultra durable electronic ballast which has a 50.000 hours average rated life with a 90% survival rate.
The average rated life of the GreenPower and Daylight bulbs are 16.000 hours with 80% lightoutput remaining.
The heat that is generated on the lamp surface is not transferred directly to the plant, but indirectly, with air acting as a carrier. Using the open reflector concept, a natural air current is created, with which the heat is distributed evenly throughout the environment, thereby preventing the formation of hotspots on the plant. The Reflector allows heat to dissipate away trom the canopy, greatly reducing garden hotspots and increasing overall lamp life (less heat build up).
Daylight lamp
The daylight lamp is optimized in a broad spectrum growthlight with an increased share of blue light. The lamp can be used for the growth stage of the plant.
GreenPower lamp
De GreenPower lamp is optimized in a broad spectrum with a peak in the 660nm DeepRed area. Because of the peak in the 660nm DeepRed area results makes the plant more generative which results in a stronger bloom of the plant in the flowering stage.
