    new member looking for education and advice on leds.

    Warranty? Whats the warranty on a set of knees climbing up/down the ladder hundreds of times over years to replace hundreds of metal halide bulbs? Do bulbs/ballasts/transformers/... never burn out? What good is a warranty if you have to pay 5x more for the light with a fancy name attached to...

    Cree XM-L vs. Luminus SST-90?

    I wonder what would happen to the SST if Cree came out with LEDs as big as the SST50, 80, 90.....? 5-10mm² Cree flashlight LED? add xpg2/xpe2... to that above chart?

    You won't be able to easily build a light with 3mm, 5mm, or 10mm LEDs. And, they won't retrofit into a housing because you'll need a big waterproof heatsink/fan. I have a light with 400 5mm Nichia LEDs and it puts out maybe 1600lm. Do you really want to play with and solder/wire 7500 LEDs and...

    Any news on Switch light bulbs

    http://ledsmagazine.com/news/9/9/23 We might see some 100w LED equivlants A21's in a year. Switch who??? Just kidding. I wonder if Switch could make that bulb with other LED suppliers. Or, add more Rebels so we can call it the Luxeon showerhead bulb..I think there was a pun intended there...

    Advice on Outdoor Ice Arena Lighting

    Please list the suppliers of these $500-700 quality 100w LED floodlights. Last time I checked, GE and Cooper were still pushing $1500. I found an 80w Lithonia for $800 and Rabb for $600. I also think in local USD. Canada shipping/taxes/$/customs is unknown to me. Instant on $200 Chinese...

    Advice on Outdoor Ice Arena Lighting

    I won't disagree having seen the cree/citizen/bridgelux/sharp... LED fixtures from big name manufacturers. Semi, I'm talking about the <$200 import generic which IMO will match the fade of the HID. Not all can afford the $1000-2000 fancy LED fixtures. I think that 5k-10k hours on a generic LED...

    New BR30 LED Bulb reduces color temperature as it is dimmed

    Going to have to put this light on the buy list to compare with the available CFL and LowesDepot LED bulbs. Still a bit warm for me but only seeing it in action will determine if its compatible with the kitchen, hallway, living room, or somewhere. Hopefully, the LEDnovation bulb will force...

    NEED HELP WITH ME LED LIGHTS!

    Powered by what? a battery, or your AC outlet? What brand/type/pn of LEDs? What kind of light, multiple 30w individuals, or a single big 150w? Can't really help without real details. Research your components prior to purchase so that you won't need help from dying.

    Advice on Outdoor Ice Arena Lighting

    Watt for watt, LED and metal halide are similar in the lighting areas that I've seen. I haven't seen one trump the other at the same watt rating. Not sure why some members here are trying to compare 100w LED's to 250w metal halides. Failure comparison! 200w incan is pretty pathetic and I...

    Time to move to LED?

    No, I wouldn't move yet. Unless you're completely dissatisfied with your CFL, I'd wait. Unlike many ranting/raving about LED lighting, the available replacement bulbs are still lacking. The few BR/R/PAR LED bulbs that I've tested ended up outside in security/motionsensor mounts. Sadly had to...

    Solar Security Lights

    ~16x7ft isn't too large of an area to light for safety. Most of those security, PIR, motion sensor... type lights do work well, as long as you don't trigger the lights excessively. But, I do recommend that you waterproof them with some silicone sealant and nail polish. And, its always best...

    Solar panel project for low voltage landscaping lights

    I don't care what, anyone with a calculator, or someone who thinks that they are the greatest professional, thinks. Go out there and BUILD SOMETHING.

    Solar panel project for low voltage landscaping lights

    Unless you know all variables, your calculations are worthless. So, quit trying to figure out why my systems work perfectly, and why I have updated plenty of failed overpriced 'contractor' built systems. Math vs experience and what does/doesn't work in the real world at the location, for the...

    Solar panel project for low voltage landscaping lights

    Never had an outage. Any assumptions of such are false. Calculations and real world don't always coincide. The only issue is snow which needs to be removed(winter re-angling the panel, rain-x, and a little panel cleaning eliminated issue). Clearing/cleaning panel should be expected and...

    Lighting advice for a Tiny House... LED light bar?

    Micro-houses sure are cute. But some cost more than a simple ranch, mobile home, camper, RV, or 'boat'. For lighting, you need to choose between AC or DC. Once that is done, it'll be easier to build/source... what you want. Don't add the complexity of having a light use both AC and DC...
