@GARDENFIRELED Man those are some rough words. Instead of trashing someone who a lot of people consider a subject matter expert. Why don’t you tell us your qualifications to make these remarks? I’m very curious as you seem to know a lot but you will have to let everyone in on your qualifications to...

I didn't find anything in the 420nm in a 2835 but I did find a decent UVB in that size VioSys Z5 LEDs. Did U go with the 2835 over the 2020 or 3535 for price or? Thanks for the reply. The 2835 package was chosen for availability and price of both LEDs and Prebuilt / Pre-Engineered PCBs (Had already...

Cheers Any reason U didn't leave a couple Sammy's on the board? (I haven't looked at the data sheets I imagine they have dif electrical requirements?) Didn't need the additional White LEDs (intended use as PC-Red Supplement) and also the Polarity (Anode - Cathode) is reversed as noted in the OP... ...

Nice work and great idea! The link for the Samsung strips is like 6 bucks though U mentioned 50 cents? Maybe I'm reading this wrong So U basically upgraded the Samsung strips with the surplus line? So U ended up with spare Samsung diodes? I must have missed something Thanks Thanks. Just got the Sam...

I agree the eb strips are the best bang for buck right now

Because of the optics on Buddies it makes them much better for suppliment strips as they blend better into normal white strips or boards. https://growlightsaustralia.com/product/buddies/ Im working on a blu...

Initial testing will be performed next week on these DIY Lumileds SunPlus Purple 2.5%, 2835 Strips... DIY Luxeon SunPlus 2835 - 32 LED Strips.jpg They will be compared to the Commercially available strips from; https://eng.e-neon.ru/ Commercial Sunplus 2835 LED Strips... https://eng.e-neon.ru/catal...

The sunplus 2835s do not use the most efficient chips. They have nice colours but will be poor efficiency These LEDs would work for my use / application supplementing White LED strips, even being less efficient, especially since they are more readily available at my location (US).
