if you look at lm the breidgelux vero 29 1750k decor seems a good option as im designing a pcb with 1000 lm561c leds on 800 3000k and 200 4000k and wanted to add reds so thought adding the vero29 1750 might be the best option over lots of indervidual reds simuar pcbs are using about 20...

i have found this cheap ir camera that can be used to measure plant health . i had the idea of trying to use this data to automaticly adjust led lighting blues uva and reds and to also adjust feeding etc this does seem to be quite complicated how ever but im shore its possible was in idea i...

im trying to work out what would be better 1 breidgelux vero 29 1750k decor or about 20 red leds possibly a mix of 10 of each ish Lumileds Luxeon C Red Lumileds SunPlus 20 Deep Red is there a simple umol calculator in excel or somthing that will convert the data i need

does any one still have the calculator as its not on drop box any more thanks

you can have them made compleatly they will do the gerber pcb file for you and put the leds on etc at a cost the more boards you have done the cheeper it gets at they charge you a setup charge etc im looking into haviing my boards made in chinna then have the leds put on in the uk but i suspect...

can i ask who made your boards im looking to do the same and have some made i have found a few on alibaba with some good quotes im looking at making 300x 300 boards with a prity dense amount of these leds on

i just made my own uniseals by casting two originals in silcone rubber , then using a marrine rubber to make the seals with polyurethane composite el110h/bk or el230r/bk . i did this as uniseals are so expensive these come in at about £3 each

i was told i didnt need resistors by the manufacturer how ever the wizard i used realy thinks i do

well these come in at just under $60 each if i order 100 with 702 leds on , if i feel i need red i might add a 49.2 size hole that pops out so you can add a BXRC-17E10K0-C-74 1750k 80cri . i thought the puk that pops out could function as a small cob on its owen and could...

they are 300x 300 im debating less however i can always turn them down getting a quote in the morning im getting a small batch made to test then will look at perhaps selling these once the design is tweeked i may add some reds to the design but the leds are hugely more expensive

the funnyest thing ive just by chance stumled across the manufaturer of quantum board s and they are going to make mine happy days with even more leds

I've been thinking about haveing made some pcbs with over twice the leds (624) on around the same footprint as a quantum board I'm thinking of adding the option of perhapes some reds to the board also . Or the ability to add a cob like a bridglux 1750k I'm thinking this as i can have these...

you can prob save by using invotronics drivers as they are much cheaper than mean well with realy good effency and use vero 29 c cobs

does any one know what lv flux is as i was looking at red leds and intsead of lm they are using lv is this a new type of flux as these leds say 400lv cree reds are 80-100 lm so is lv better ??

im trying to work this out my self i was lookig at running more cobs at 1050ma or slightly higher so you get realy good effecncy and more protons etc you can run 10 cobs off 1 invotronics 400w 1050ma driver and im also going to run them passively was looking at a combo of these cobs...

ok im looking to build a light using these vero29 se i thinking of using 5x BXRC-35E10K0-C-73-SE <----less light more red 5x BXRC-40E10K0-C-73-SE <--- these seem to throw out more light but are more blue if i use BXRC-35G10K0-C-73-SE lf i use these would this give me even more reds as...

im looking to build light thats runnig 10/11 vero29 3500k at 700ma- 1050ma any one else doing this as from what i can gather its the most efficient

im looking to build light thats runnig 10/11 vero29 3500k at 700ma- 1050ma any one else doing this as from what i can gather its the most efficient

i must admit its tempting to get 4 of these quantum boards and put it together this with some extra reds

i just saw these Quantum Boards aswell how do you like them how would you compare to say cobs ? on the driver front the the Inventronics EUD-200S105DV 1050mA 95V~ 190Vdc 200w dont look bad they are the same drivers that growmau5 freind at chilled are using in there light and are a fraction...
