Old tech, but I've had experience with em'...if you could use a simple contact closure to monitor, use a "current relay". To whit here's a link to one on ebay which maybe be just what you need (the relay coil is a heavy winding in series with the load)...

As far as z-wave dry contact sensors, it looks as if we're stuck with using a "window/door switch" type module either with a separate "dry contact" connection (or a fairly simple hack to disconnect the reed switch and make bring out an external contact connection). Aeon Labs has been...

Try this Link from LED's Magazine that discusses the liquid cooling (plus of course a product video...). There's a similar bulb out there already (Hydro 4 or something to that effect...), that says they are using a Paraffin Oil of some type for their cooling fluid...

Thanks for taking my RR address out, more SPAM I don't need! Switch Lighting mentions a $20.00 price point, of course pricing and release date are like when a company says something like "later this year", I always would like to ask them "just what year are we talkin'"...:).

These look interesting, if the price and release date (4th quarter) holds. An unfrosted version would probably sell well as an object of "techie art" :-) http://switchlightbulbs.com

Freed up my power meter and (at full on) reads 5.9 watts at 120v. Power Factor is .72, and projected operating cost (@ 10 cents per KWH) is $.42. The 60 watt halogen it is replacing (the Sylvania isn't quite the brightness of the 60 watt, but I'd give it a 40-50 watt. in apparent brightness)...

Did a check on stabilized temps near the base of the bulb heatsink (warmer there) and got at stabilized temp in 68 deg ambient of approx. 111 deg F at approx. 50% dimming and about 150 Deg. F at 100%. I'll get a power reading when I manage to get my Brand Electronics Powermeter disentangled from...

Yep, it was one of the HA07s (no ground), but given the low current I had no clear idea of how it would work, well until four hours later. :rolleyes:;) With the Sylvania though, the HA07 runs cool. The bulb heatsink fins just run slight warm to the touch. If I get a chance I'll use an IR...

The Dimmer (the Triac failed), the lamp lived. After a few days now the Intermatic Z-Wave dimmer and Sylvania UlTRA LED A19 at least so far, seem to be doing well.

Picked up one of the Sylvania A19 Bulbs yesterday at my Local Lowes for $19.95 (reduced from $30.00). So far so good and (fingers crossed) is working OK with my older Intermatic Z-Wave dimmer module. I tried a dimmable CCFL bulb with one of the Intermatics quite some time ago, and the "magic...

Although not an LED light, I've been watching an outfit called Vu1 which looks to have just got UL approval for a CFL which uses a non-filament electron source to light the bulb phosphors like an "old fashioned" CRT. According to them the dimming should play nice with most dimmers and the price...
