I am looking for a product I heard about that is similar to Silver Solder. It a matter of heating it up & pouring it in to fill any gaps.

If there is any visible gaps or you want to run stringers.... Just heat up a cone and give her a good few Whaps with the hammer
She will fit right in the gaps and if you have the gas up you will be mint....
Although im sure your more than fine now seeing the shawdy heatsinks i have seen on car amps/ballasts running tripple or more watts/amps the fins are half useless anyways and your way overkill .

Not going to do any more welding on them except to connect the fins to the end caps. To much weld and it will warp for sure. There is only 3/8" between fins so the only way to do any more weld in there is with some aluminum stick rods & they are very messy. The Loctite stuff is the answer to bold it all together.

This looks awesome so far! The heat sync is a massive beast, love it.

When looking into the acrylic, did you manage to find some that doesn't pull out some of the light's spectrum? When attempting to make lids for my tank I ran into this issue and ended up scrapping the project. $200 worth of acrylic lying around now

Are you planning to put any bracing in for the acrylic? That stuff likes to bow like crazy in higher humidity and temp.

Looks pretty impressive so far. Out of curriousity what is the weight of that beast?

I haven't looked for the acrylic yet but will be stopping at Sabic next time I go to Calgary. I am going to use 1/8" or thinner & will be held in place on all 4 sides by the frame of the heat sink.

I would guess it around 50 lbs each, but I will have to actually calculate the weight.

Patience grasshopper, patience just got my last 2 drivers tonight & hope to work on them some more this weekend in between work and finishing a buddies stand skirts.

I am going to get at least one done & test drive it beside my 2 - 250w MH & 2 - T5's fixture for some comparison.

That makes 2 of us, wish I could take a week off work and just work on my tank & LED's but it will not pay the bill o I have to settle for what time I have. Also working on a 2800 sq ft dog run to top it all off.
