Home Made LED Panels

[pan4gold49]

I guess after looking at ways to grow and seeing threads on using Leds for lighting.
I looked at 168 led panels, supermotojoe setup and Irie prycon lights.
DYI Panels

First was led selection. Since they come in all sizes 3mm to 10mm I chose 10mm.
The 10mm is the biggest bullet size with a big lens without going to 1 watt.
Next I found some leds that had a 70,000mcd over the 5,000mcd led found in most 168 led panels.
Since the leds also come with the resistors needed for a 12vdc supply.
I will be making 12" x 12" panels of 125 Leds. 72 red and 40 blue leds like moto's panels.

I am hoping for 9,000 lumens per panel with a 30 watt power requirement.
Led order has been placed in HK hope to start this weekend

Sounds interesting cant wait to see what you come up with. I will be keeping up with this post and good growing.

Right on. Very interesting indeed..

Hi yall.

The LED order has been shipped from Hong Kong. I ordered 200 blue and 300 red
this will be enough for 4 ea 12" x 12" panels and 1 40 LED Veg panel. Each 12" will use 2.24 amps @ 12vdc so I can use old power packs or a car battery or an old computer power supply.
As far as lumen's go this has been a chore to calculate. 125 point sources a 15 degree lens a 24" focal point you get the picture. Thanks to excel this is 9400 lumen. With 4 panels this should get about 36,000 lumen's. The veg panel will produce 3300 lumen's but have not laid out the panel size yet. I was going to build my veg cabinet but a snow storm has stopped me in my tracks. Crap snow already!!!!

Your going to be very disappointed with these LED's. They seem to work alright for small vegging plants but not much anything else. the yields gotten from them (if any yield at all) has been reported as dismal. Personally i would have used my bucks for decent HID's which guaranty a yield. Good luck though.

^ I agree..

Racefan I am looking for a new way to grow. This will also work on 12vdc a good thing for solar or wind power. I did a lot of research into the panels and leds. I found that most leds used in those panels 3,000 mcd red and 5,000 mcd blue. Also have to look at the lens of most leds have wider diffuser 30 to 45 degrees . The led I have chosen are 70,000 mcd with a 15 degree diffuser that's 439 lumens at the focal point and 303 lumens at focal point times 2. Since this is no box here I will be free to explore the possibilities.

off topic but notable - Re: your sig: Have you ever broke your scale and had to weigh your weed at the local produce stand?

Nope, but back in the day we used the postal pkg. scale at the US Post Office on the first floor of the Federal Bldg.....didn't dawn on us to use a grocers scale - but all was uneventful, went well, was an incredible rush, and makes a great story to 'tell the grandkids...'

All I can say is...good luck and keep us updated.

hey man great effort with the led light cant wait to see an assembled panel or some operational shots right ...keep us in formed i am very interested in the solar aspect of led light so hook em up grow something and show us some results please ...im very interested in this and hope to see more

I think that it will be the only way to go once Obama introduces his carbon credits after he signs the Kyoto Protocol. Then there will not be much of a choice addapt or die lol.

Hi Yall.
I was hoping to get the leds today but nope. Got the tracking info it left New York on the 7th. Thats weird Hong Kong to New York then back to the west.
Got the frames cheap one's at wally world. I been thinking on how to aim 500 leds ?

Hi yall.
Well the leds are here big 10mm round and brite wow! Very little dispersion thats good they will reach into the canopy. I have my camera charging so will post more later.

I'm looking forward to this- if those make as many lumens as alleged, then I have a feeling they might do well for you. best of luck man.
