Thank you Alpo0721
I have no complaints with the viparspectra. I have switched to a QB but Iâm definitely not throwing out the vipar. It got my lady to this point then I swapped to the QB.

u r gonna see the difference with great lighting.!!
i have never used Vipar LED, butâŚ
taking in consideration the spectrum and efficiency,
HLG QB is roughly twice as good as Viparspectra.!
400-1000w HPS is probably 50% better�??
light is the food for your plants, better light means better growth and better flowers.
Nice looking
You are correct at double the output at 136w. Both running at 136w the ppfd for both lights at center is roughly 500 @18â. But as you start venturing outwards, the ppfd for the vipar 12â from center is about 100 less than the QB and at 24â from center the vipar drops off with QB at about 215 where the vipar is at about 80.
The vipar was also less than 1/2 the price of the QB.

that is the price u pay for mediocre instead of great.!
great lighting sucks to purchase/run, but worth every dollar if u want great bud.!!

I use Viparspectra and have had good results, I recommend the par series , with led sometimes an extra light is needed to get a good footprint . I have two lights in my 4x4 and there growing like crazy . They work great for me , Viparspectra is very decent but electric sky 300 is the best !!
Itâs working little by little. using a combo of cfl and Fiet grow light until I can get the bigger ones
Iâm curious as to what specifically makes you say that, or what lights you are comparing to? I feel itâs a good light, but I couldnât find any categories it was better than every other light available.
About 5x the amount I have to play with. You guys had good ideas BUT, you didnât listen when I explained my situation. I HAVE to work on a shoestring budget.

Hps is as good or better than inexpensive led. A âgoodâ led fixture is better than hps fixture.
@dbrn32. To me itâs the best because itâs basically a stretched out quantum board which has all the color spectrums covered from 2700k - 6500k by alternating the leds , the leds look like the Samsung v2 board leds . And it has a lens which focuses the light of the quantum board for way better light efficiency. Itâs basically just a well built quantum board with a nice case and the driver built in to the case. But honestly you could easily build a stronger quantum board way cheaper

Thatâs fair. Unfortunately theyâre 20% less efficient than quantum boards.
The lens actually blocks light in order to give higher intensity reading directly below. So its technically less efficient if measuring power in against light out.
Iâm not sure what led theyâre using, but the listed photon efficacy seems too low to be lm301b or equivalent. I guess my thoughts are for the price you donât even have to build a light to be more competitive. Based on two fixtures for 4x4 at $1400. Thatâs same price as latest fluence fixtures that provide pretty much same light spectrum. The fluence fixtures run 2.7 umol/joule vs the electric sky 300 2.0 umol/joule. 35% more efficient for basically the same price on a fluence fixture.
The one thing they have going for them is a commercial light specifically designed for 2x4. The industry seems to be lacking there.

The leaves drooping or curling? Watering issue or PH? Maybe atmospheric?
To much water or to little water.
@dbrn32 - Do you know anything about the Illumitex Neo Solâs? I think they have a rectangular footprint but at $1,500, I am not sure⌠just curious⌠
It does, awfully expensive for 1.6 umol/joule. Their flagship light is the neo par, much more competitive with latest and greatest from other manufacturers at 2.7 umol/joule

The price is really high⌠not sure why. I donât see anything âwowâ that would suffice 1.5k .
Thanks
