You could upgrade to a Metal Halide, replacement bulbs may be easier to get for you? Otherwise I suggest doing a plain old web-search for what you want, "150 watt halogen bulb UK" or whatever locaton, should turn up some stores near you.

Good luck,
Steve

Jessops uk (photography store) do like 400w OHP halogen bulbs for cheap but you''ll need to upgrade your transformer to 36V which you should be able to find in maplins or RS.

1. Ballasts ARE cheap if you know where to look. Old shop lights work, old street lights...etc I paid $55 for my ballast with a bulb and reflector included! They look less then 3 months old. Even the local hardware store sells them, I got a second one that is 175 watts for $30 total!

2. If you are unhappy with the 150 halogen, you must upgrade the insides to take a bigger wattage bulb anyways. This is why I said you might as well upgrade to a Metal Halide light, they put off less heat and TONS more light as well! You COULD add a second light but you will still need to deal with the extra heat and a power supply of some sort.
