I’ve been going around and putting finishing touches on the many projects that I’ve written about previously. I wrote previously about the custom solar powered LED light system that we built, but we hadn’t come up with a nice aesthetically pleasing design for a light switch and dimmer knob to control it. So we hacked…
Next test of prototype walkway lights
I wrote yesterday about hacking a 220V AC walkway light to use 4 of our 7W LEDs. After testing it, it was painfully bright. We intend to put individual dimmer circuits on each light pole, but why waste money on unneeded LEDs just to dim them? So we switched it out to a single LED…
DC solar powered walkway lights
We weren’t so happy with our options for outdoor DC walkway lights so we decided to try buying normal AC walkway lights and hacking it. We decided to buy this model from HomePro for hacking: (The photo here is at HomePro and shows it with an AC 220V compact flourescent bulb inside for display.) It…
Temperatures of new solar powered DC LED lights
I noted at the end of this previous post that we the heatsinks seemed to be getting too hot when we first tested the LED lighting. The heatsinks were getting up to about 90 degrees Celsius. So in our final install, we roughly tripled the size of the heatsinks, and the results were quite promising. We…
LED light final install in bathroom
Today, we finished up the wiring of the LED lights in the bathroom and had our first test of an actual install of our new DC lighting system. When we tested previously, it was just temporarily put in place as a proof of concept. But the concept was proven and we wired it up and…
Wiring up the LED lights
We are using small gauge VAF cable to wire up our DC LED lights now. VAF cable normally has a white PVC insulation on the outside for protection, so I decided to try make it blend in with the wooden walls better like we did with the PVC conduit piping. In addition, Praew really doesn’t…
New experimental LED lighting
I blogged about receiving these new LEDs off of eBay a few weeks ago: but it took a few weeks to set up a real test in the house. We attached these LEDs to flat aluminum heat sinks, and I finally got around to testing it on Monday by swinging by the new house after…
Very high power warm white LED
We’ve been exploring different options for DC 24V lighting in the house using solar panels to charge a set of 4x 6V lead acid golf cart batteries. Our previous LED light tests worked but the light was a cool white which I’ve never liked for home lighting. Also, the previous test used 0.5W LEDs which…
