I tried to install in my room of my father home the Philips ML 160W yesterday (2.dec.2010) and the high amount of light, the 100hz flickering, the moderate (65%) CRI and the strong UVA and heat, gave me a headache, and i feel that i can't continue to use this type lamps in my room .
Also our winter probably seems that it will be warm and very dry, with little rains, to be justify the use of a 160W SBMV heater in my room .

Funny enough I used one for years as a room light, it was just the right amount of light. Luckily I had mosquito netting on all the windows, though I did have to spray it regularly with pyrethroid, to keep the small bugs that had a near teleport capability down to a manageable level, mostly dead in a heap outside the window.
