I calculated the payback time in upfront cost vs power saving and it ran into the decades. While there are loads of cheap and nasty LED's on the market at the moment I have also seen some quality ones appearing around the $50 range that equal the output of a 50w halogen. Paying $100+, crazy, they simply will never pay for themselves.

They work with the existing transformers etc, but this can lead to their downfall. The more expensive lights, like the D900, are built and installed with their own entire setup, meaning there is virtually no risk of fail. Because of this, they can design the light to produce more light. With a higher output, fewer lights are needed, resulting in a payback. It may not be as fast as the cheaper lights, but if building not replacing lights, it is definitely the way to go.

Sure, but there are "full kitt" options just like the brightgreens for under $50 as well with similar lumen output.

You would have to ask questions though, when all leading products are closer to the $90-$100 mark. Do they satisfy all criteria, lifetime, CRI, equally as efficient? I think a lot of the cheaper ones don't have the lifespan and could be susceptible to failing early due to higher operating heat. Re: Feedback on Brightgreen D900 LED 25Oct 16, 2012 3:42 pm As said in other posts, we purchased Wattsaver LED's. So far we have no problems with them. The output was equivalent or exceeded Brightgreen's. They cost around $45 for 70mm and $65 for 90mm. They have I believe a larger heatsink than the brightgreen, so I don't think heat will be a problem.

Being a new field of technology, I tend to be a bit wary when some products aren't covered. Re: Feedback on Brightgreen D900 LED 27Oct 20, 2012 12:54 pm As per their website they come with a 5 year warranty Settlement 1/2/12 New Shed 23/3/12 Slab poured 27/3/12 Frame complete 4/5/12 Roof complete 1/6/12 LOCKUP 29/6/12 Our new build blog http://kareenhillsownerbuild.blogspot.com/ Re: Feedback on Brightgreen D900 LED 28Oct 23, 2012 9:13 am delatite13 As per their website they come with a 5 year warranty Having a look now at some of the Wattsavers. Is the extra cost for extended warranty very much? The ones I'm looking at have 2 year warranty or 2yr extendable to 5yrs. Are the drivers expensive to purchase as well? Re: Feedback on Brightgreen D900 LED 29Oct 23, 2012 9:23 am As per their home page " Here at Wattsaver we have a minimum warranty period of 3 years on imported products and 5 years, extendable to 10 on our locally manufactured lighting. " The lights we purchased are locally manufactured NOT imported. They are assembled here. We didn't consider the imported ones as the specs etc of the local assembled versions was so much better at not much more cost. Also if you check their price list (under "information" on the right hand side and says "price list") for the lights we purchased the DL9 and DL7 the driver is $9.95 when purchased with the light. All the info is there.

Re: Feedback on Brightgreen D900 LED 37Oct 24, 2012 5:33 pm Re the dimming. The amount of dimming varies depending on which dimmer you use. From memory Stephen from Wattsaver recommended a HPM trailing edge dimmer for the best results. I have a different one that he said didn't dim as well as the HPM. I think that was the one recommended but if you shoot him an email he will tell you for sure. As for the percentage of dimming, yes I could handle it a bit dimmer after the dimming levels of halogen, however it really doesn't take long to get used to the slightly brighter level. It in obtrusive to me when watching tv or similar.

Brightgreens EDIT - Just received the Luxman dimmers in the post today. Installed them and now the Brightgreens dim right down to as good as 0%. So clipsal dimmers into the bin Only problem with the Luxman is they dont fit in the Clipsal Saturn plates perfectly, but with a bit of modification I think I can get around it. They would fit fine though in a standard CLipsal or HPM plate (White ones) https://forum.homeone.com.au/viewtopic.php?f=38&t=44762 My Owner builder journey extending a 1930's Bungalow As title suggests, looking at using the interlocking Pentablock stacked stone products to replace failing timber retaining… 0 17868 |
