as previously stated they are side lighting and yes they do put out some heat and they do put out plenty of lighting for the purpose that they are serving as yes i will get pics or video of my room to show you or anyone and no there not being used yet because my plants are only in the second week of vegitation. cfls here range here from 10 to 15 each so mabye much cheaper there. those lights are better than you think but i guess it depends on the persons opinion ive never grown a plant with them alone i've always used a metal halide to grow and just started using the halogen two years ago and they havent failed me yet but as i stated before its not advise just my opinion and i will get some pics up soon. (im not here to debate subjects nor to give advise just opinions)
