I have attached a picture of a real LM301B LED and a Fake LM301B LED for you to see above, the real LED has the butterfly solder, the fake LED has the the dual square soldered backs. All our LEDs and products are 100% Genuine from Samsung, CREE and Mean Well!This listing is a private listing all buyers are kept anonymous. Guarantee, you can return them for any reason. We do not recommend the dual spectrum boards as well, where the board contains CREE 660nm and LM301B together on the same board I will explain why. This is because the CREE XPE2 LEDs run up to 2w per LED and the Samsung LM301B typically run at 0.2w per LED, running them at the same current you are only getting 10% of the light output from the CREE LEDs.
So if you had 8 CREE 660nm Red LEDs on a dual spectrum board you would only be getting 1.6w of red light output! This is why it's advised to run these using a different driver and on completely different boards. We run the CREE XPE2 LEDs at 1.5w per LED on our boards so for 20 of our CREE XPE LEDs you would get 30w of red light output. Also not to mention the cost of the CREE XPE2, as they cost substantially more you will be saving on cost run the LED chips at their recommended output rather than 10 / 20% of their output which combined LED strips / boards do.
I also have 660nm boards in stock EACH BOARD HAS: 20 units of CREE XPE2 LEDS QB20 with 660nm xpe2 which can run up to 30w Again genuine CREE XPE2 LEDS you can search on google. We recommend CREE XPE2 board per 2 Samsung boards. We also highly recommend using 3500K when running 660nm LEDs, this is the same spectrum combination all of the top LED grow light manufactures use inducing Spectrum King and H. This spectrum is best due to increased canopy. 3000k is however better if you are not using the.
It is also better to use heatsinks with fin backings as they disperse heat far greater especially when running the boards at higher output. The heatsinks we supply all have fins.
In this listing you are purchasing. 4 units LM301B 3500k Boards with 288 Samsung LM301B LEDs.2 units of dual heatsinks. 1 unit of Meanwell HLG 480H 2800B (These run at 480w).
1 unit of dimmer for the HLG 480H 2800B. HLG-60H-C1050 is also a option this would run the CREE XPE2 LED board at 22w.
But these would run 10 units of LED strips. They should be here on the 4th of November. If you would like 3000K or 4000K boards get in touch.
