Help decided which strips

[colbygingles]

As I look to finalize the strips I want to use for my terrariums, I am looking for some feedback. Below is an overlay of 3 strips compared to Chlorophyll.
Bridgelux Thrive
Bridgelux EB3
Samsung HB282
I am balancing looks with plant growth and am using 5k Kelvin.
Taking lumens into account for brightness, which strip would you personally use? I like the samsungs due to brightness but am wondering if the Thrives will perform better due to their high spectrum even though they produce less lumens.

Any strips you would consider?
Heat is a huge factor and minimal heatsinking is required. I do have them mounted inside a 100mmx35mm aluminum profile.

I will try to get some thrive strips and test for performance in the next few weeks. Its the only way to really know performance for sure.

I look forward to the results. I really want to try their 5700k strips but everywhere has an MOQ of 200. Know where I can get smaller quantities?

I havent looked at availability at all, usually if they have a high moq it means they are not in stock yet. Normally someone let's me know when the new bridgelux products are in stock and sends some to me for test results. I will have another product in about 2 months that will be an add on for normal bridgelux strips to increase the blue region of the spectrum correctly. It should be a pretty good product and will cost about $60 including driver. This way you can buy the high efficiency EB gen3 and then buy my add on later. Plants don't care too much about CRI, they are more interested in spectrum overall

I am taking the Samsung H-Series out of the running as they are running just to hot for me. I cant seem to get them dialed in to run cooler unless i go CC. My entire design is based on CV wall adapters for plug and play capabilities and at 20V they are way to dim, 24V they run way to hot.

I might try and find a 22V wall/laptop power adapter for more testing.

Grow Lights should be (First) "Sized" by Grow Area and Plant Specific Growth Stage... download/file.php?id=4438
and SPD Charts (Spectral Power Distribution Charts) alone don't provide enough info for best comparisons, you also need to know the Percentage SPD (%B-G-R-FR)

But if you're looking to match a Driver's or Power Supply's fixed, non adjustable Volts and Amps (Watts) with a LED Strip then the Selection should be with the strip's rated Vf (Forward Voltage) and Watts.

Example A:
LED Driver 24 Vdc 25 Watts;
Samsung LT-H562D, 80 CRI, 5000K, 560mm;
2080Lm , 193Lm/W (29PPF, 2.7PPE)
10.8 Watts (480 mA)
22.5 Vdc
25 Watts (Driver) / 10.8 watts per Strip = 2.3 strips req'd
560mm Samsung LT-H562D (H-Series)... https://www.digikey.com/en/products/det ... US/6149748


Example B:
LED Driver 24 Vdc 25 Watts;
Bridgelux Vesta-2750G, 90 CRI, 2700/5000K, 560mm;
3352Lm, 135Lm/W (57PPF, 2.3PPE)
25 Watts (1000 mA)
24.8 Vdc
25 Watts (Driver) / 25 watts per Strip = 1 strip req'd
560mm Vesta BXEB-TL-2750G... https://www.digikey.com/en/products/det ... 13/7899252


Comparisons of Percentage Spectral Power Distribution (%SPD, %B-G-R-FR) show Bridgelux 90 CRI LED Strips have better spectrum (% SPD) for plant growth than Samsung 80 CRI LEDs, even when they're supplemented with added 660nm, Samsung 5400K Horticulture L2 strips (~6500K plus 660nm) are;
UV - 0
B - 22.8
G - 34.8
R - 40.9
FR - 1.5


SPD (Spectral Power Distribution) Percentage comparisons


BTW, Both Samsung and Bridgelux LED Strips typically run cooler when powered below half (< 50%) of Maximum Rated Watts...

Thanks @PeteR_1


I think i am going to stick with the Thrive and mix 5700 with 3500 for my purposes. Now to figure out a way around the 200 MOQ for my one single test fixture.

[colbygingles]

Amps are seemingly a lot lower than advertised?
Testing a single 560mm strip wired parallel
20V 60W 1.2A CV Driver pulling 290mA
19.5 V 75W 3A CV Driver pulling 110mA
Or am i converting my decimal point way wrong?

The fixture was scorching hot when running 20V.

What driver are you using?

[colbygingles]

Disregard, I have it figured out.

Know anywhere that has the eb 3’s in stock in the US? I can’t find them anywhere.
