    Reflector for bridgelux LED?

    I have the Bridgelux BXRA-50C2600-B-00 I was wondering if they made 32 mm reflectors for this? http://www.digikey.com/product-search/en?WT.z_header=search_go&lang=en&site=us&keywords=976-1085-ND&x=13&y=13&formaction=on

    Heatsink 6 LED's at 350mA

    I have been wondering maybe someone can help me out.. I how can you cool 6 LED's but getting the heat away from the LED's in a enclosed fixture that's mounted on a wall outdoors? I would assume it needs to be passive cooled?

    4000+ Lumen Test & BridgeLux LED Review

    I know this thread is old but I have a security light I want to retrofit, I was looking at the BridgeLux BXRA-50C5300-H-00 I just don't know if a 5 1/2" 6 1/2" aluminum heatsink is enough to cool one or two of them? Would I be better off going with smaller LED's? I need at least 6800 lm.

    My LED Worklight Project

    This was the thread I was trying to find.. I was thinking about doing the same to my flood light since the bulb blew and hard to find a replacement. But curious how the heatsink is mounted.. did you have to drill or anything like that?

    Cree Star and problem

    At this point I don't think the LED's would ever turn off.. sun does come in the window in the day but unless it's hitting the LDR it's never going to be bright enough.. I think I'm about to order this larger LDR to see if it helps since these are so small.

    Cree Star and problem

    :) then that makes sense :) One question on my buck I'm using a photocell aka LDR to dim the LED's.. however they don't dim that easy.. like turning on the light in the kitchen they still pretty much stay on.. However if I hit the LDR with my LED flashlight from maybe 15 ft away I can see the...

    Cree Star and problem

    Wow I really gotta mix some white in here.. I wonder if I could put one more star... I did not know royal blue was going to be a bit Uv'ish.. I have a stack of green papers that turn a bright green and all my LED's with yellow dies all glow under the the XR-E

    Cree Star and problem

    The stars or maybe the screws must be conducting on the bar because just touching my soldering iron anyplace on the bar causes the first LED connected to the buck to glow faint. Ahh never mind got it finally

    Cree Star and problem

    I was doing 13V then moved to 19V.. maybe I got the wiring wrong? it goes pos-neg from the driver and then pos from the first star to neg to the next? Don't I need to wire back from the last star?

    Cree Star and problem

    not sure what's up.. I just mounted two royal blue Cree XR-E's on a alimum bar with mounting screws.. So I wried in series and the LED's wont come on at all I'm using a buckpuck to drive them at 700mA

    How bright?

    Well I can almost 100% assure you that they know nothing about bright LED's.. you and I and everyone else here knows it's painful to look at so we look away.. I'm saying a normal person who knows nothing about this.. The camera wont be near the LED's but near by.. one other thing I'm trying to...

    How bright?

    So I think I understand what you are saying each LED star gets it's own PowerPuck but say if 6 is 4140 is that going to be enough to startle somone to look up at the LED's? What' I'm trying to do is have a PIR to trigger them to come on but It's a 12V PIR and the specs are.. - Rated Voltage...

    How bright?

    I understand it's 3 LED's on a star that's why I said a single tri-star The whole design will be switched on by a PIR.. (short story) The long story is it's for a room about 10Ft by 12 Ft room was broken in and I will be putting a camera in the room which has IR.. However I know when it's dark...

    How bright?

    I found the LED here http://www.luxeonstar.com/Neutral-White-4100K-20mm-Tri-Star-Rebel-690-lm-p/mr-wn300-20t.htm One question OK so if I do 3 instead of 4 will a 12V power supply be enough for it? the Vf for a single tri-star is 8.5V so I would need to up the power it seems which is not an issue.

    How bright?

    I'm not sure what info you are looking for but the supply voltage is 12VDC I've never driven that many LED's in series before.

    How bright?

    I should have no problem driving them with a 1Am power puck driver right in series?

    How bright?

    If you have one LED that's 939 lm at 1A how bright would it be total with 3 other LED's also at 939 lm?
