Today I will finish my H-Series build for tomato seedlings just in time, as a couple of my tomato seedlings are just starting to peek out from the soil ever so slightly. (I'll probably also use this light for culinary herbs, orchids, and/or playing with hydroponics after the tomatoes move outside). ...

Great tip! I've never heard of that stuff before, and it does indeed look very useful. Thank you again for your help!

If you are worried about it then buy some liquid electrical tape. Chances of you shorting them are minimal, liquid electrical tape is pretty cool stuff to have kicking around.

I just realized that the Cutter strips have non-insulated Wago 2065 terminal blocks. Should I cover these with something to reduce the risk of electric shock from accidental contact, since the PCBs will be exposed, or am I being paranoid? What could I use to insulate them?

I have the power supply and dimmer, and I'm expecting the light strips and heatsink any day now. But it will probably take me a little while to get around to picking up the wood and the rest of the bits and pieces. I'll post a photo and a parts list when I get it done. @MadCowTX how is the build pro...

I think I've decided that 80 Watts is overkill for orchids and ornamental houseplants, so I'm going to go with 2x Cutter Cree J-Series 560mm 90CRI strips (www.cutter.com.au/product/ssk-1560-3590cr/). I'll mount them on 4-foot 1" HeatsinkUSA, which should give me plenty of heat dissipation and a slim...

Would this heatsink be sufficient for 2x 4-foot EB gen 2 side-by-side at 1050 mA (84 Watts)?
EDIT: Keep in mind that this will be enclosed on four sides by a wood frame, so air movement will be limited.

Thanks for that tip! Unfortunately, using C channel does complicate the design I had in mind. I wasn't planning to have any screws on the outside of the frame. I was imagining a simple 4-sided wood box with a 1/4" ledge on the inside so it could just slip over and rest on top of the aluminum bar. Ha...

On further consideration, I think I'm going to build the wood frame because it will look nicer and cost less. Do I need heatsink for 2x 4-foot EB gen 2 strips side-by-side at 1050 mA (84 Watts), or can I get away with mounting them to a length of 3-inch wide flat aluminum bar (the top will be uncove...

For my first LED build, I’m trying to figure out how to make an aesthetically acceptable 4-foot LED bar to hang over a shelf of houseplants in my living room. I’m thinking I will shoot for around 80W but probably run it dimmed to about half that and hanging 18-24” over the top of my plants. So far, ...
