24V LED Floodlight (48 x 5050 RGB LEDs)

[kane]

What sort of price range would you be thinking? (I haven't priced other version so I have no idea)

Can't say I've thought about what they will cost yet. More than $5. Less than $500. Zat help? LOL

I'll take 10 at $5 then

I'd been keen to see what you can offer these at David. I've just built my first two rainbow floods which was a lot of fun but I might wait to check yours out before I get any more from SE.

Im in for 20 at $5

deffintly in for 6 to 10 of them if board/BOM are reasonable. Can't stand my Rainbows, burned up 3 out of 6 so far. 2 from user error, 1 just had a melt down ??? I use them 365 days a year on landscaping lighting

Like the DMX option (while I would prob use a DC board). Let us know if they will run on 12vdc. (please)

This version is 24V (or a little higher) only. A 12V version could be done with some pokery jiggery. Maybe even selectable 12V/24V, but we'll leave that until I get the first one back.

Oh, Pokery Jiggery. Love it when you get all technical

I'll certainly be interested in a few myself. Have been speaking to my new next door neighbour, and he's happy to get his house involved with the show - and given their house is basically a big white box, it should be perfect for a bunch of rgb floods.

Prototype PCB is back and built:

How soon can you get us a completed one David?, Just for seeing how they go in real life.

What's the constant current value?


assuming 160mA

[David_AVD]

Phil - yes 160mA per colour. Have given it a quick test to confirm CC works in the 21.8V to 32V range. Have not run for long enough to gauge heat dissipation in the CC regulators.

 

[David_AVD]

First picture is ambient light from the light pole out the front. Others are each colour by itself. I think the camera makes the colour look more saturated than it really it. That said, it was quite reasonable in brightness. The garage doors are primrose (cream) in colour.

ohh very nice indeed. 24v the only version of this?

Im thinking i could use a few of those next year

 

[David_AVD]

I went with 24V to keep the current (cable losses) down and reduce heat in the constant current regulators. That said, I need to change the design a little as they run too hot for my liking.

 

[DeeJai]

i really wish you would stop designing and making things, i think i have already pre-spent my next 5 years worth of budget just because of you.

AS for heat, im guessing that the floods for a display would only be on for a few seconds at a time.. but thats probably just my thoughts
