Grow sun 160 watt 12 band vs. 300watt (192w true watt) 10 band generic

Just added a grow sun 160 watt on Friday. It has 20 watt multi chips in it x8. Has built in timer and a remote control. Has seedling , veg and bloom settings. You can adjust the intensity of the light from 10% to 100% in 10% increments. Multi chips can be replaced without soldering. You just unscrew the ring around the lens. Pull the lens out then the reflector and the cob come right out , just pop a new one in reassemble and your good to go.

Thought i would start this thread on it since i could not find much on these lights after searching. So going to give it a whirl and see what it does.

Took pictures of all the cycles and timer but only a couple turned out. Stupid camera doesn't like to focus sometimes.




Unfortunately i had a light leak threw a vent that has put the plants on the right about two week behind the plants on the left. I am not going to do this very scientifically no divider or separate spaces for the two lights. The grow sun is hanging on the right side and the ebay special 300 watt (true watts 192) 10 band is on the left. Should be able to tell if one side does better then the other.


Will add more pictures in about a week. By then the new grow room should be completed so they will be in a new home. Peace

My bad they are multi chip and not cobs.

They dont give much info on the spectrum besides the range 400-760nm & white.

Would have to look into removing the lenses, Thinking the lens helps compress the reflector and led chip into place. So i might have to crank up my metal lathe and make some rings for that to work.

no wattage draw and what sort of white light are they using?
wattage draw on bloom at 100% is 160 watts. They dont tell you the spectrum besides the range.

Here is a bit more info from a ebay seller that is selling these. Not sure how true it is Since since some of these LED light peddlers Will tell you the Sun is green if they think it will sell you a light.

LED’s – Custom Bridgelux and Cree 20 watt true draw LED chips are made up of full twelve bands scientifically calculated for best spectrum with maximum photosynthesis results possible using LED light while reducing light waste from approximately 80% (HID lighting) down to less than 5%. This makes it the best and most efficient way to grow. Twelve bands cover 400nm to 760nm. Each 20 watt chip compares to twelve 3 watt chips of high quality and about 25 3 watt chips of standard to lower quality.

The good news is, if in fact the MCs can be removed, you should be able to replace them with a combination of CW an WW chips

They can be removed Although it has some screws that need to be taken out first. Looks like just the Reflector is held in by the lens from the video they have. When i get my grow room done and move the light i will take a closer look at it. I think the Led chips are soldered to the removable PCB. So i would have to design a PCB etch and solder mask. Then reflow the led on it. Pretty much green when it comes to these LED's though, besides making a 100x 1 watt array of UV leds for curing UV curable solder mask my main focus is designing variable voltage vaporizers.

Here is their video on chip removal [video=youtube_share;4Zmxkc2W_Xo]http://youtu.be/4Zmxkc2W_Xo[/video]

You want to research for drop in CW and WW replacements

2 CW in the middle the rest WW, and again dump the reflectors! While they control the direction of the light, they hold back 10-15%. At best, it's a wash, but it's much better than that

You can test it if you can operate one or a couple at a time. Aim it to the floor from ~ 2-3ft

It will be interesting to see how well that pcb set up works in the long run. I suspect they will improve on it, so, as their efficiency improves ,you can swap them out.

Most DIY uses emitters hard soldered to a heat sink. PITA, and not without problems, such as cold spots when solder paste does not flow 100% evenly between the chip and the heat sink

Yes subbed in looking forward to the journal i was looking at the multichip fullvspectrum on ebay for my journal but im doing a diy led panels

Make sure you save this picture as a guide to see how long before noticeable light degradation

Well i added another light so this wont be much of a comparison. Someone else posted a journal in here with the grow sun 320. Believe he got 250 something grams off of one plant. I would for sure check that journal out if your interested in the grow sun. Link to thread https://www.rollitup.org/t/eshine-growsun-320w-complete-grow-dark-devil-auto-45l-airpot.820286/

Here are a few pics from today. Got the Candy Kush back left . The Indica is back right She is slow , going to be 10 plus weeks on her. Thinking about dropping the Indica next flower cycle and doing two Kush. Front are both Strawberry coughs. Due to light leak issues one on the right is almost 3 weeks behind the one on the left. Still kicking myself in the ass on the strawberry on the left. It was a weak cutting and didn't notice till i got home from the store with it. Also didnt help I let it get locked out once.



Here is the New light i add a DIY CXA3050 2700k ....Adding one more today, when I finish building it.




Kush is my favorite





Some Strawberry
