    A lady went into a grocery store and looked into the turket section. She needed a bigger one for her family, so she asks the stock boy: \"Do these turkeys get any bigger?\"

    The stock boy replied: \"No ma'am, they're dead\"

    Halogen light is not very suitable for plants. It produces alot of heat and the majority of the light is nonusable for photosynthesis. So although it appears the plant is nice and bright the plant in reality is 'seeing' little of the brightness. You would be much better off with a couple compact fluorescent bulbs that screw into standard incandescent fixtures. Try and find as high a wattage as possible and preferably a daylight or coolwhite type.

    Hi,
    I agreed with Tony.
    The 100 watt halogen will produce about 1600 ~ 1800 lm Color temp at around 2800K, but product a lot of heat.
    In Singapore GE sell a 60w compact fluorescent (CFL) that gives out 3300 lm at 6500K (daylight). Otherwise you could use 2 or more 20 watt CFL daylight (1200lm each) from Ikea.
