Indoor MOD 420 Horticulture COB Lighting

[HLG1]

MOD 420 is a universal frame for assembling a COB lamp with hundreds of different configurations.
Developed by @Bobby from Mi and myself.

The original prototype was Mod 8 for 8 cobs.

We redesigned it to accommodate 4 cobs

The final version of Mod 4 comes in 2 pieces can be can be joined to make a complete 4 cob frame. The COB distance(center to center) is 12" However we plan to add a 14" option soon.

An optional link can be added to join 2 or more frames together.

Where to Buy:

Frame is available here

Heatsinks and other components available at northerngrowlights.com
Frames will be added to northerngrowlights.com soon.

I like it mate...simple and effective..

Assembly is quick and easy. No drilling, no tapping, no soldering, and no hassle.

Start by bolting on the driver and junction box.


The driver can be connected to the potentiometer (dimmer) and the AC power cord at this time using the Wago connectors that are supplied with the junction box.


Next you can install the heatsinks on the frame.


All wired up.

With the exception of mounting the COBs to the heatsinks and installing optics thats the whole assembly. Takes about an hour. I left out the COB install do to there being so many options. We can get into that later on.

Compatibility List

Heatsinks
Mod 4 is compatible with SST 105, SST 120, SST 140 and SST X
SST 105 - is suitable for under driving cobs to 35 Watts or lower
SST 120 - is suitable for driving cobs to 50 Watts or lower
SST 140 - is suitable for driving cobs to 80 Watts or lower
SST X - To be released in 5 weeks. Suitable for driving cobs to 120 Watts or lower

Theses recommendations are on the conservative side and no air movement. You can dissipate more power as most grow spaces have a good airflow.

COBS
These heatsinks come presrilled for popular COBS. The COB that can be used depends on the Heatsink used.

Currently SST 105 and SST 120 is available in 2 options
Option 1: Compatible with Bridgelux Vero 29 and Cree 3590
Option 2: 35mm spacing Compatible with Cree CXB/CXA 3070, Citizen CLU048, Bridgelux V22, Bridgelux Vero 13, Bridgelux Vero 18. All ideal COB holders with 35mm screw spacing listed here and here.

Currently SST 140 available in 1 option
Option 1: Compatible with Bridgelux Vero 29 and Cree 3590

COB Driver

12" frame - This option has center to center distance of COB LED of 12".
14" frame - This option has center to center distance of COB LED of 14"

The 12" frame is compatible with 3 most popular COB Drivers.
HLG-120H - 150-155 Watts - http://www.meanwell.com/mw_search/HLG-120H-C/HLG-120H-C-spec.pdf
HLG-185H - 200 watts - http://www.meanwell.com/mw_search/HLG-185H-C/HLG-185H-C-spec.pdf
HLG-240H - 250 watts - http://www.meanwell.com/mw_search/HLG-240H-C/HLG-240H-C-spec.pdf

We plan to add a 14" frame soon. The 14" frame is compatible with 4 most popular COB Drivers.
HLG-120H - 150-155 Watts - http://www.meanwell.com/mw_search/HLG-120H-C/HLG-120H-C-spec.pdf

HLG-240H - 250 watts - http://www.meanwell.com/mw_search/HLG-240H-C/HLG-240H-C-spec.pdf
HLG-320H - 300-320 watts - http://www.meanwell.com/mw_search/HLG-320H-C/HLG-320H-C-spec.pdf



Optics
Optics help you increase the light utilization by ensuing you get maximum Photons delivered towards your canopy.
These heatsinks come presrilled for popular Optics. The Optics that can be used depends on the Heatsink used.

All Heatsinks (SST 105, SST120, SST140) are predrilled for LEDiL Angelina Reflectors.

SST120 are predrilled for popular 100mm glass lens. Glass Lens from different suppliers may not be the same. Verify that the diagonal mounting positions 112mm before buying the lens.
100mm glass lens are available in various configurations. Some lens may not have enough depth for COB holder and may be incompatible with your COB holder. KB-HB100-80 is compatible under Ideal holders.

SST140 are predrilled for Khatod Silicone Optics. These Type V distribution produces a circular distribution that has the same intensity at all angles.
This distribution has a circular symmetry and provides an evenly distributed light. Gives a very even coverage.
Compatible with Vero 29.
Compatible with Cree 3590 using Bender+Wirth 449 holder. Ideal holder will not work with this optics.


You can see 4 options here. No optics, Glass lens, Reflectors, Silicone Lens

It is a good idea to ground the frame. Yellow wire in the photo below.

Lots of great info thanks for posting

I would like to have a frame like the mod 8 but only 4 .. As I want to run 4 COB's in a straight line. Call it the mod 4 haha.. Is something like that in the works?

I have alot of people ask for a similar design. I have started to play around with the idea as far as where the driver, junction box would go. Thats as far as I've gotten do to ☝.

Let me ask you this, what kind of COB spacing would you like to see in a design like this?
