Browse Forums Lighting + Lighting Design 1 Jul 31, 2009 6:04 pm Not sure who the lighting guru is around here but... I was just looking at some downlights I have ordered. It says they come with the following: Fixed White Downlight Frames with twist lock front - Cutout 70mm, Diameter 80mm 12v MR16 Lamp Holder 60va Electronic Transformer - DIMMABLE Premium 50w 5000hr MR16 Globe They were fairly cheap (that being the reason I bought them) and my sparky mate said they seemed to be ok, but I didnt get him to check the technical stuff I have posted above. Is anybody able to tell me if this is any good or not?? Im mainly worried about the transformer, as I know nothing about this kind of stuff. If you need any more details please let me know. Any advice would be greatly appreciated Building 'The Kingston' (with 'Boston' elevation) through Blueprint Homes in Hocking, Perth **PCI complete 06.02.10** My Thread - https://forum.homeone.com.au/viewtopic.php?f=31&t=17607 Re: HELP NEEDED - Downlights :) 2Jul 31, 2009 6:11 pm An electronic transformer is better than the alternative; a magnetic transformer (electronic = less losses). Everything else appears standard. If you like the look and you're allowed to use halogen (for instance, in NSW, BASIX pretty well forces to you to use CFL) then you've done well.

Will that chew a lot of power?

The next step up in energy effeciency is the 35W IRC halogens (you can get these later - just the high usage ones then as they blow). The next step up is CFLs, but these will not work with your arrangement. All things considered, changing the high usage ones to 35W IRC halogens will get you most of the way to where you want to be.

There are new varities that are better suited to fit inside a light fitting , only cause they look a bit odd without some sort of lamp shade or ceiling fitting ,these are 3.3 watts ane = to 40 watts and the other is 4.5 watt and =60 watts . These are straight 240 volt and are bayonette firiing or e 27 screw in . Warm white and cool white are available ,best is not frightfully expensive. Forget Halogens as they are the biggest waster of power above anything else. have a good look areounf thse are very new. Re: HELP NEEDED - Downlights :) 6Aug 25, 2009 2:25 am Hi there NatB, The specs you have listed seem to be fine. That being said, who says that the info on the transformer is correct? Unfortunately, these days there are many cheap and inferior transformers out there that have faulty soft starts, faulty overloads, faulty circuit protections, etc. Unfortunately, it's not until a problem happens, that you will realise this. Rule of thumb - pay less & you will get less! There are always bargains out there, as long as you are comparing name branded products.
