the local pet store is the easiest but you can order cheaper online/ebay. Penis EnlargementTCO will have a selection. There are a few things you want to take into consideration.
1) Clay or Infrared. Again i have had both. The clay is great heat but i think you need a stronger bulb. It also takes a few minutes to heat up. a negative to clay lamps is that you may leave on or burn yourself because there is no visual indication of if it is on.
2) Wattage. Again 150W is fine with infrared. You need only to buy a bulb and a bulb cage referred to as a "clamp lamp". I am sure you can go to 250W and be ok, you will just keep this farther away from your penis.
3)DLD to answer your specific regarding "sun lamps" I am not sure if you are referring to infrared and serotonin. the below is a clip from infrared in wikipedia
Heat
Main article: Thermal radiation
Infrared radiation is popularly known as "heat" or sometimes "heat radiation", since many people attribute all radiant heating to infrared light and/or to all infrared radiation to being a result of heating. This is a widespread misconception, since light and electromagnetic waves of any frequency will heat surfaces that absorb them. Infrared light from the Sun only accounts for 49%[9] of the heating of the Earth, with the rest being caused by visible light that is absorbed then re-radiated at longer wavelengths. Visible light or ultraviolet-emitting lasers can char paper and incandescently hot objects emit visible radiation. It is true that objects at room temperature will emit radiation mostly concentrated in the 8 to 12 micrometer band, but this is not distinct from the emission of visible light by incandescent objects and ultraviolet by even hotter objects (see black body and Wien's displacement law).[10]
Heat is energy in transient form that flows due to temperature difference. Unlike heat transmitted by thermal conduction or thermal convection, radiation can propagate through a vacuum.
The concept of emissivity is important in understanding the infrared emissions of objects. This is a property of a surface which describes how its thermal emissions deviate from the ideal of a black body. To further explain, two objects at the same physical temperature will not 'appear' the same temperature in an infrared image if they have differing emissivities.

I do want to comment on lighting in general and this is a very important and not understood subject. these are differences of opinions on this subject but mark my words. If you work in an office environment and have flourescent lighting overhead like everyone does, take these bulbs out, and replace them with Full Spectrum Lights from Home Depot. Light enters our eyes and the quality (wavelenghts) directly impact the pituitary gland. It is documented and proven that flourescent lights raise stress levels and alter the natural release of hormones via the pituitary.
If you replace these lights you will become familiar with the soft blue tint in the early morning before the sun shines in your eyes. This light is so much easier to sit under and you will probably notice a difference immediately.
I am just sharing something i have used over the years but do not need now as i do not work in this type environment.
