What are you guys using for cheap frames and heat sinks for led strip style lights like the bridgelux EB series? I’ve got some EB at a inch width and some kingbrite style that are 2inch in width two strips in one. The last time I built my EB light I used aluminum flat bar that I ordered from the internet and chopped down to size for each strip. The two inch wide flatbar is expensive. I looked at heatsinks from heatsinkusa.com and dam $$. I was wanting to build a decent frame and have each strip on a heatsink to help make them last longer.

cheap heat sinks for led strips?

Its hard to know for sure I'm not an electrician. Can you give some more details or post a photo? Someone will come around and help you.

get a cpu heatsink and DIY with that. cheap and efficient
You could use aluminum U channel - available at Home Despot etc in 8' lengths. Buy 1/2" and cut and bolt/glue pieces together to get your 2" and to increase surface area for heat sinking.

They are very responsive to emailed questions
Not my photos these are from the tank light builder forum some tech nerds there for sure
Be sure to click the see more link in the post!!!
Bluefish controller always wanted one of those to mimic the strain im growing native climate perfectly
What driver and how many EB do you wish to run ?
I did a cob build and the hardest part is a quality frame and heat sink bars try the 4x4 canopy with the flat bars
Think you will be happy with the modular build and quality you can stack that fame light or heavy with multiple bars id think but id email the guys over at rapid led and see what they recommend for the tank light builder guys, prob what were looking at above?

Solar irradiance - Wikipedia
Solar irradiance is often integrated over a given time period in order to report the radiant energy emitted into the surrounding environment (joule per square metre, J/m2) during that time period. This integrated solar irradiance is called solar irradiation, solar exposure, solar insolation, or insolation.
Irradiance may be measured in space or at the Earth's surface after atmospheric absorption and scattering. Irradiance in space is a function of distance from the Sun, the solar cycle, and cross-cycle changes.[2] Irradiance on the Earth's surface additionally depends on the tilt of the measuring surface, the height of the Sun above the horizon, and atmospheric conditions.[3] Solar irradiance affects plant metabolism and animal behavior.[4]
The study and measurement of solar irradiance have several important applications, including the prediction of energy generation from solar power plants, the heating and cooling loads of buildings, climate modeling and weather forecasting, passive daytime radiative cooling applications, and space travel.
Common questions I ask myself is, how much light do I need to make the plant perform to the best of its ability? My garden outside looks like it struggles at full sun, but thrives on cloudy days.
Does my dimmable LED need to run full power all day ?

Figure 1. A simplified representation of the suppression of genes having the proteins and photoreceptors present during the functioning of 24 h circadian rhythm. In the presence of light, these photoreceptors Cryptochromes (CRYs) and Phytochrome B (PHY B), which are represented in yellow and pink squares, help in the functioning of genes and proteins; along with the formation of two different negative loops. That is, these morning loop genes [CIRCADIAN CLOCK ASSOCIATED 1 (CCA1) or LATE ELONGATED HYPOCOTYL (LHY)] combine with Pseudo-Response Regulators (PRR7 or PRR9) and suppress the action of CCA1 or LHY (represented with black lines with arrows). On the other hand, TIMING OF CAB EXPRESSION (TOC1) combines with GI, which then leads to the activation of the TOC1 gene. ZEITLUPE (ZTL) is activated with the help of GI, and then GI itself combines with ZTL and suppresses the function of TOC1 (indicated with the black lines along with arrows).

Yeah. Or buy aluminium sheet and use that.

My cheap option is also U channel. Though China pricing for something better isn't high.
Don't be tempted to polish them, as they won't work as well. Likewise, black is a much better radiator, but paint is adding insulation. Just as it comes is technically acceptable.
If you want to bond two thinner ones, some heatsink plaster is useful. It's somewhere between paste and epoxy. I have little cobs stuck in place with it, so between some U channel it's alright. Not staying wet like paste, or expensive like epoxy.
Obviously coppers thermal conductivity is great for pulling the heat from the individual LEDs hot spot quickly. There is an option to use a thin copper sheet to get that pull and spread going, in a composite design with an alloy backing. Some CPU blocks can be seen using this idea. Where the CPU contact area is copper, which is implanted into a larger alloy block. I have my cobs plastered to round copper disks, that are plastered to alloy heatsinks. As the contact area increases, the thermal conductivity of the material matters less. In your case, a thin copper sheet could be used to get the heat from the package, and transfer it to the alloy channel, which is the designs physical strength.
It could look quite good. Kinda steam punk.

Here's my old light..I used aluminum flat bar that I ordered from the internet and it was cheap..now it's expensive I guess from covid or whatever. It's the same flat bar for the frame and sinks. I think it cost me $30 dollars to built it. looks like now with what I need I'm looking at $100 minimum.

Most of the stuff I buy for things like this is from Mcmaster Carr. The more specific you are in what your looking for helps with pricing. Always look at multiple sources before you buy.

U-profiles are the best option when it shouldn't be too pricey.
I think at some point it doesn't make sense buying expensive heatsinks, you can rather get more stripes for the money.

Dont underestimate the need for proper heatsinks and thermal interface materials. More strips do not make sense if you cannot cool the ones you have. Always use proper materials for the job...you wont regret it. Skimping out now means replacing stuff at the worst time...like 4 weeks into a grow. I have NEVER regretted building something right the first time. I have however regretted going cheap.
peace, negative.
