Bridgelux EB series gen 3 strips
I can give you one of Vestas at a few different currents. I can only generate an IES file once I have done a test. I guess I could upload one here in a zip file. It would need to be tomorrow as I'm not at my computer today

I really appreciate that! I am looking for EB Gen 2 and F-Series at the moment. I might end up buying some Gen 3 as well. I Might send some your way for testing. I am really appreciative of what you are trying to accomplish. Transparency is key!
It depends if I hear back from bridgelux. I want to create lights for 3 4x4 Chambers. 12 lights per 2x2 driven at min 30 watts and max 60 watts. So a total of 144 strips. I'm wanting to use the hlg-240h-c1050a for each 2x2.
I'm interested in the IES files because I'd like to know how high I can hang the lights to maintain a minimum of 600 ppfd at 240 watts.
Actually I have a question if you don't mind. If my forward voltage during startup is higher than the driver range, what will happen? Will the driver just reduce the current until the lights heat up and the vf drops?
Here is my situation. The max output voltage of the 240h-1050 is 238v at 1050ma. The expected forward voltage of 12 eb gen 2 strips at 25*c is 240v. But when they reach stable operating temp the vf is 236.4v. Can the driver cope with that at startup or would it reduce the life of the driver? I don't want to run in parallel, hence my delima.
I really appreciate the help.
You would have to take a good look at the graphs to see the voltage drop at different temperatures, in theory they would take full current once they have heated up, but if they can not get enough current to begin with they may not get hot enough to drop voltage enough. You could also get an odd voltage bin that was a little higher than the specifications and your lights may not turn on at all. It is much easier and safer to run things in parallel.

Do you know of someone using such power levels? thats like 60w/ sq foot. 5.4 DLI per hour. PPFD should be closer to 1500 then 600BirdBare wrote: ↑Sat Aug 03, 2019 3:05 pm

Hate to shit on your idea, but the connectors and boards of slims are not rated to handle 240v. afaik their listed at 60V with the caveat that maximum voltage depends on end application.BirdBare wrote: ↑Sat Aug 03, 2019 3:05 pm

Good point, I have never built or designed a product to work with high voltage in series, to me it increases the risk of fire and electrical saftey. I have been in the game for 13 years and have always run products in parallel, now more than ever due to tight voltage bins it is safer.

Honestly, I'm depending on a normal voltage level bin. I know at 700ma, from others experimentation, the temp and voltage levels stabilize around 45*C and 19.5ish Vf. I hate running things in parallel because from my point of view, if one fails they will all fail. Also from a DIY perspective, everything has to be close to perfect. Definitely not my style. I like quick and easy. Series does that for me.TEKNIK wrote: ↑Sat Aug 03, 2019 9:02 pmYou would have to take a good look at the graphs to see the voltage drop at different temperatures, in theory they would take full current once they have heated up, but if they can not get enough current to begin with they may not get hot enough to drop voltage enough.

Edit: I was wrong, Stabilized around 19.26vf at 43.4*c

I'm referencing this thread: https://www.rollitup.org/t/samsung-f564 ... ld.953509/ I am more interested in this being an all fits one lamp. I want to be able to set this at 5-7ft away and still get decent par levels. I looked at getting a hlg-185h-c1050 but I do not believe I will be able to increase the height more than 1 ft. away. Please change my mind!unkle_psycho wrote: ↑Sat Aug 03, 2019 9:44 pmDo you know of someone using such power levels? thats like 60w/ sq foot. 5.4 DLI per hour.
