Par lights?

No, do not use parcan floodlights.. they are the wrong spectrum and you want to use either HID's like Metal Halide or High Pressure Sodium. Or if you can't afford those, go with Florescents like CFL's or say a Shop Light which houses two 48" bulbs.

Floodlights give off wayy to much heat and will do nothing for your plants. Read the Grow FAQ at the top of the page. I think, like many others probably do, that it will help people like you who have questions like this become educated on all aspects of a sucessful grow. READ UP AND SMOKE UP!

its not worth the effort of modifying a lite, it the wrong kind and too hot. go with what marky says hes write, hps, mh or flos

It is not the light it self I am modding. It is the socket. I like the design for the mount and all. I did read the grow faq, but will re-read it but didn't see anything on the parcan floodlights either as that or as par lights. The problem with the socket/holder is that the floros won't screw in because the ballast is too big around. The simple solution is to cut off the very end 1" or so of the lamp holder. I don't need the end of it anyway since the actual light itself will not fit inside of it. I just want the mount to be able to get my lights above my plants. I'm going to use splitters in the socket to give me two lights per holder with 42w cfl. Thanks for the help on this. When I can afford it I plan on purchasing a HPS security light and modding it like in the grow faq for my uses. Right now I'm just slowly getting things together.

Photosynthetically Active Radiation (PAR) would work with many kinds like.. High Pressure Sodium Lights..

Plants require red and blue light to produce sugar using photosynthesis. Historically, humans have grown plants outdoors where abundant sunlight is available. Indoor gardening requires a different approach since sufficient natural light is usually lacking.
Plants perform best in an environment with a combination of red and blue light of sufficient intensity. Incandescent lamps (as in the traditional Edison light bulb) are good for providing light for everyday activities, but are inappropriate for driving photosynthesis, since they have little output in the blue range and much of their energy is converted to heat.
Standard fluorescent tubes are adequate for some plant growing applications but specially designed plant grow lights produce high outputs in the wavelengths required for maximum biological and energy efficiency.
High pressure sodium (HPS) lights produce an intense illumination and are slightly biased toward the red end of the electromagnetic spectrum. This makes them ideal for plants that require a red shift to promote flowering. Sodium lamps may be employed singly, or in combination with metal halide lamps if a more balanced color spectrum is needed.
Like most conventional style bulbs, HPS bulbs emit light in all directions, so as much light as possible is directed toward the plants by using a reflecting enclosure over the bulb. Sodium lamps get hot so they cannot be placed too close to plants. They also emit ultraviolet light, so adequate safety precautions (UV absorbing glasses and skin protection) should be observed when working around them.

Better way to have these with metal halide flood lights.. Hope you have the info now..
