Don't see any screws... what's holding the strips on? Thermal tape?This will be my veg and flower light.
I'm using the Meizhi while they are still small and once they get large enough I'll switch on my DIY frame as well.
Let them veg for a couple more weeks then. Flip to flower.
I wouldn't even bother - its just going to make a big fat hot spot in the center. Be much better off putting a couple more of the TCI strips down the middle, and lose the MehziI'm also running a Meizhi in the middle of all of this
Is that the 2.079 from Heatsink USA?I think these will do nicely.

Yeh, I used a thermal adhesive to stick them on. If for some reason it fails to do the job, I'll screw them down like I did on my previous 'build'.Don't see any screws... what's holding the strips on? Thermal tape?
I don't have any spare TCI strips at the moment, and I like having the ability to raise/lower and switch on the two lights individuallyI wouldn't even bother - its just going to make a big fat hot spot in the center.

Two more bars with four more strips total should fill it in nicely.Yeh, I used a thermal adhesive to stick them on. If for some reason it fails to do the job, I'll screw them down like I did on my previous 'build'.

However, as soon as I can afford more strips, I'll be adding another 5 and replacing the Meizhi all together.
In your opinion, How many strips would you recommend to replace the Meizhi?
The Meizhi draws around 250w (from what I've researched) and 5 strips at 23w each totals 115w, but earlier in this thread I seen someone say they had 5 strips drawing 154w..
So are the diodes in these TCI strips that much more efficient?Two more bars with four more strips total should fill it in nicely.
Its not so much about total, its about evening out the spread. That meizhi is going to make a huge hot spot in the center.So are the diodes in these TCI strips that much more efficient?
Because the Meizhi is drawing more than x2.5 the wattage of 4 strips. (I know the Meizhi is just a cheapo light, but 2.5 times less efficient seems a bit of a stretch.)
I'd love to be able to replace it with just 4 of these TCI's!
That looks like the '600w' Meizhi 277w actual. rough numbers... but the Amazon page says 16500 lumens for that light.. that's about 5 tci strips.So are the diodes in these TCI strips that much more efficient?

grab one of those lux meter apps... numbers are helpful in a relative sense... useful tool to determine hot spots. Helped me figure out that my cob led fixture was way too close to the canopy, too bad I measured at the end of flower.@nfhiggs @Hairiest_Stamen thanks for the advice, just seems to easy to replace a £110 light (Meizhi) with £40 worth of these TCI strips.
I'm not doubting the numbers, but I'll have to stick with this set up until I can get 5 more strips.
I grabbed some stuff from ebayWould someone mind throwing up a link to some thermal tape/ adhesive that you have found works well? Just trying to get an idea of what your are using and what may be available here.
Thanks in advance.
I'm still slightly confused as to how the switches work, or rather how I know what mode they're in without having a way to measure.More playing around. Have one of these lighting some seedlings. Forgive the crap cable management.

4 power levels using supplied driver..measured with a killawatt:
26w
24w
19w
17w
Also... measured back of supplied driver temps... 120F in the center of the driver... Hot!
Not sure it's a great idea to lay the drivers directly on the heatsinks that are cooling the strips.
