    How sweet of you to promote the product your boyfriend is selling. And you call me a troll? I have zero commercial interest here. Cannot say the same for you and your boyfriends.

    Seeing you know so much how is it the output of a driver looks like this? It appears to me the switching frequency shows at the output of the driver and in the LED string. What am I missing. You said it would be smooth.

    That's so sweet. You and gangrene707 working it together. You comment screams TROLL.

    LED Panel F-Series GEN 3 or Bridgelux EB Series Gen 2

    There are many variables to the PPFD. Mainly the height. At a height of 1 meter a 1000W HPS has a center output at 400 µmols/m²/s according to Cree. Figure about 100,000 lumens for an 1000W HPS. So if the strip is 5,000 lumens you need 20 of them for the 1000W equivalent. Using Inverse Square...

    LED Panel F-Series GEN 3 or Bridgelux EB Series Gen 2

    The BXEB-L0560Z-30E2000-C-B3 is still at $11.84. It was $7.36 in January.

    Absolutely. It does not hurt to try new things. Making our world a better place. Your knowledge on Bluetooth is impressive. I am surprised BT Mesh is moving along so quickly for a spec first finalized mid 2017.

    Pwm 0-10v led controller

    I came to the exact same conclusion. Yesterday I ordered half a dozen. They are cheap enough that just the terminals to connect the Mean Well driver to a cord makes them worth while. I'm tired of soldering on a plug. I will use some on my household lamps too so Alexa can turn them on and off...

    They are new. Not yet released. I don't like being a pioneer and debugging someone's stuff.

    LED Panel F-Series GEN 3 or Bridgelux EB Series Gen 2

    The difference between the Samsung F-Series and Bridgelux Gen2 strips is negligible. I bought samples of both. I went with 14 of the BX Gen2 because they ran cooler even at 1400mA. The BX Gen2 are in short supply. Arrow is the only one with stock now and they raised the price from $7 to $12...

    osram oslon sll or lumileds luxion which is better?

    I had not heard of LitePlacer. I was looking at openPnP. http://openpnp.org/ I had two Zevatech Placemat 760s. This photo was taken just before I drove the moving van away. This is just some of the stuff I left behind. That's a conversion oven in front of one of the Zevatech 760s. There...

    It appears the bluetooth is "bluetooth mesh". Not sure what level of programming you are familiar with (e.g. firmware), but using zigbee and bluetooth could be a major undertaking. Unless user level apps or APIs are provided.

    Help with cob

    I agree. It's difficult to make a 11x11 with 98" angle brackets. The size of the actual fixture(s) depends on the size of the strips and materials used. Probably more practical to use 88" and 44" dimensions. My head hurts thinking about it. But you are right, multiple smaller fixtures.

    Not so sure that is true. In a constant current driver design the max current can be adjustable but is typically set in design parameters for efficiency. As the max current load changes, to maintain efficiency, the switching frequency and output inductance must be balanced. In switching...

    Why not? It's actually better to do it that way. When you dim, the duty cycle of the PWM is reduced. At 1700ma if the duty cycle is 100%, at 1000ma it's 59% (1000/1700) This means the output is turned off 41% of the time. This increases the life of the LED about 40%. NOTE: There are...

    osram oslon sll or lumileds luxion which is better?

    By far the OSRAM Olson SSL have a higher efficacy. I like the Luxeon C Line, but they are too small. Can only be assembled by an expensive pick and place robot. And rework (replacing) would be a bitch. What I like about both of them is their wide view angle. Wider has better uniformity...

    That's how drivers do the dimming. The 0-10V signal changes the PWM dimming duty cycle from 0-100%. It's a constant current driver. What's the difference between current settings and dimming? All I had to go on is the attached PDF. Not very clear. Why?

    Why? It is an unreleased new product. Documentation sucks. Do you have a Bluetooth Mesh compatible controller? It's very new technology. It says the dimming is 10v PWM. What's programmable?
