    Filament LED

    Re: Next generation Filament LED Look at "figure 2" in that article. Heat vs lifespan. Lifespan of LED jumps RAPIDLY from 30K hrs to 300K to 1 million hrs, dependent on temp. This is a rather interesting new filament idea also... https://www.youtube.com/watch?v=Nme8T2yLhL0 The poster says...

    these bulbs have no heatsink?

    You like HEATSINKS? One of the more efficient 100W equivelents. A 16 Watt GE. P/N 13909 Another from General Electric 165 Watt led165-m400-740 125 Watt Hyperikon P/N 501080538 Does this heat sink remind you of the "old-school" air tuned capacitors? Another way to...

    Cree bulbs with detachable glass

    Should call it the "Home Depot/Cree LED Lending Library" program! I think the best way to combat the whole heat problem is to UNDER-drive, by dimming, or buy led's with huge heatsinks. GE makes a 100W equivalent, INCREDIBLY well heat-sunken lamp (mod 13909). Consuming only 16W, I find it one...

    If you have a Menards near you, KILLER deal for Sylvania par 38. 20 W for a markdown price of $5.34.

    LED floodlight for back garden

    Seems kinda expensive. Why not get a fixture like this under your house's eave. http://www.homedepot.com/p/Heath-Zenith-110-Degree-Outdoor-White-Motion-Sensing-Security-Light-2-Pack-SLI5408WH9PP18/202351711 I hope that fixture is metal--stronger. And put 2 par lamps in it. Less than $30...

    these bulbs have no heatsink?

    Its almost as if I can see your lips move, but I can't hear a WORD you're saying! This message is hidden because SemiMan is on your ignore list.

    these bulbs have no heatsink?

    Call me "ranty" if you will, I'd call it an engineering compromise. Those of us that want a well heat-sunken lamp can still have them. Why should you or Semiman care. The theme of the thread seemed to be that many like the old-school (might we call it) LEds With heatsink. This is a vinyl vs...

    these bulbs have no heatsink?

    You snipped almost the entirety of my post, which was, linking some great deals to those upthread that desired LED lamps WITH substantial HEATSINKS! What rhetoric? More heatsink--lower junction temps--longer lasting lamp! FACT: LED output and lifespan reduces exponentially by time and...

    these bulbs have no heatsink?

    Yep, I long for the days of creative heatsinking! And as far as not being that popular, if you stage your buying when the retailer dumps them at HUGE discount, you save BIG. Depending on where you live Menards has closeout A19 equiv Sylvania's for $4. Forty and sixty watt equivalents. REALLY...

    SlimStyle CRI 90

    Depending on where you live Menards has 2 sizes of 93 CRI Sylvania Ultra HD Par 30 and Par 38's on closeout for $7 THATS RIGHT FOR SEVEN DOLLARS! The Par might be a little harsh tho with its 40 degree beam spread. https://www.menards.com/main/p-1444431958768-c-7482.htm?tid=-8709662500090934783...

    Philips announces a new but strange looking bulb

    Interesting... Was that switching power supply emitting RF? Was it interfering with HF or VHF receivers? Or was it interfering with the anti-lock brakes or some such thing? Oh how our lives have become SO complicated. Still resisting the computer controlled automobile, and driving my 30...

    New here...im wondering about these Feit 93 CRI BR30s

    Nice find on this HIGH CRI lamp! A little Google search finds this warehouse is Costco for $10 each. In store AND online. Plenty of insightful reviews to read about this lamp on their website also. Incredible price, considering the Philips L-Prize is STILL selling for $30 on Ebay! L-Prize...
