Having money left over for the old in-n-out with a gal is not the same thing.youre blinding them with science!
i do love the ol' in-n-out with my gal
That's last generation as far as I know. Better off with the 3618, but I'd run 6 at 150W if you want to replace a 1000Wer. Citizen and my digitized data says that puts you at 2000 umols, combined with real world measurements, maybe a bit more. Harder to say at high currents.Anyone have info on the clu550? It seems like it would be awesome to replace 1000w hps with 4 of them run at 250w each
Whats the price on those? I was thinking the clu550 at 250w would cost less than 250 but I didn't look up heatsink cost. And it might shut up all the hps guys that preach about penetration hahaThat's last generation as far as I know. Better off with the 3618, but I'd run 6 at 150W if you want to replace a 1000Wer.

Actually this is something I discussed briefly with @Growmau5 in a PM, if you combined a couple of these https://www.cdiweb.com/ProductDetail/ICELEDULTRA-mechatronix/573532/ for $14 with a couple CLU058s running at 150W, you'd have a $200 monster, driver included. That's the loudest cheapest light I can think of.Whats the price on those? I was thinking the clu550 at 250w would cost less than 250 but I didn't look up heatsink cost.

What's wrong with them? Serious question. @nevergoodenuf mentioned but didn't necessarily recommend them to me.I have a couple of those heatsinks I dont think I would buy one again I'll do a little more research I'm thinking a CPU cooler might be a good cheap option if it could cool 250w
Nothing is really wrong with them I just wasn't impressed they seem kinda cheap and I didn't like how the chips mounted to them I don't use them anymore I bought a heatsink usa bar and sold the lights that I made with those heatsinks but I know the grower that's been using them for like 6 months an they work fine I would go with pin heatsinks for future builds. There are some sweet looking high bay heatsinks but they don't show the price onlineWhat's wrong with them? Serious question. @nevergoodenuf mentioned but didn't necessarily recommend them to me.
I'd want a massive passive if I was building a 150W light for myself, but you mentioned cost.
Your thread is awesome.There is nothing wrong with the CLU 550. It's just expensive at over $100 each. This is what I have been trying to show in my thread. Running Soft right now with 1800 watts, I am only using 12 COBs (about 60 square feet). I do have a CLU550 and CLU056 3618's in the mix. I will be updating my thread soon.View attachment 3721075 I would like to see some #'s to see the difference that $40 makes between the CLU058 and the CLU550 @ 200w and 250w.
Not according to Citizen, no. The CLU550 is one generation back, like I said. So presumably the improved efficiency and thermal resistance of the CLU058-3618 more than makes up for the reduced die count.There has to be some kind of advantage to the CLU550 over the CLU058 if you take price out of it, right?
Again, I can only tell you what Citizen says, the CLU058-3618 is newer and better at all currents. Even @ 300W.i think the clu550 is like 2x 300w cobs in one while the clu058 is a single 360w cobs
so in theory if we were to drive both cobs at say 100w then we would actually be driving 2 300w cobs at 50w vs 1 360w cob at 100
efficiency should be much higher, right?
No, I'm never sure...let me check.Are you sure Jorge??? I can't use excel, but the CLU058 @168 watts is 135 lm/w and the CLU550 @ 243 watts is 134 lm/w, according to CDIwebs pages.
Well, there's good news and bad news. The good news is we are both right, and the bad news is...well, it's the same thing.No, I'm never sure...let me check.
Further investigation reveals that the data sheet is likely incorrect.Are you sure Jorge??? I can't use excel, but the CLU058 @168 watts is 135 lm/w and the CLU550 @ 243 watts is 134 lm/w, according to CDIwebs pages.
