Time to change bulbs/lights in home - cheap options for "bright white" light?

  If you want a bright white light globe you'll need to go for CFL globes. Those halogen globes you picked will still be very yellow-ish in colour. Also, don't be fooled by "energy saving" halogens, they're not much more efficient than the regular old light globes were.

  I'd suggest a 15W-20W compact fluorescent globe, I think Bunnings sell Phillips and Nelson branded globes. Also, when you pick out a CFL make sure you check the colour of the globe. Some will be a 'warm white' which is a very yellow colour and others will be 'cool daylight' or 'natural' which is the white colour that you want.

  If you want white(r) light rather than the yellowish stuff you currently have you need to look for bulbs that have a colour temperature rating of around 5000K(elvin) or above. They might be described as "cool white" or "daylight" etc. What you have now is a "warm white" which is in fact yellowish. See (at least the first few paragraphs of) http://en.wikipedia.org/wiki/Color_temperature.

  That's just for the colour of the light. For brightness you can go by the wattage (higher means it consumes more electricity but usually this is because it's producing more light), or if available the lumens - see http://en.wikipedia.org/wiki/Lumen_(unit)

  You'll also need to get one that has a B22 bayonet style mount, as it seems this is what you currently use. See http://en.wikipedia.org/wiki/Bayonet_mount#Light_bulb_bayone…

  You can get cheap-ish bulbs in supermarkets (coles/woolies) and department stores (kmart, bigw etc). Bunnings will probably have a larger range for you to choose from.

  Just an overall comment. It seems to be getting harder to get good light bulbs. The power-savers tend to be either blue or yellow, and not at all the kind of bright light I like behind my head when I'm reading or on the computer.

    Blue-ish = 5000K, Yellow-ish = 2700K

    Try for 3000K (halogen colour) or 4000K (Cool White office lighting colour)

  I want to replace bulbs in my lounge and study room. The present ones are bit yellow'ish which is bit problem for my parents while reading So we want to buy some bright white bulb.

  The colour of light is just the aethetics - blue-ish coloured bulbs are not "brighter" than yellow-ish bulbs.

  So, if they are having trouble reading, get brighter bulbs, which means higher wattage - your current ones are only 12W, so get some 18W or 20W instead
