My Impression of the Maxspect Razor 420 120watts LED (8000K)

[David]

Yup...that was max power....but I needed to cut down to 70%.....Just gotten green water all over again.....

Hi,

Saw the Maxspect Razor on my uncle's reef tank.
First impression was... wow it's slim and inbuilt fan (2).

Currently on 4 x 36W DIY PL lamp (3ft mini pellia & dwarf hair grass).
Guess's its time for a change.

I believe 120W would be sufficient instead of the 160W?
Where can I find the best deal? In LFS or online?

Thanks

The wattage difference is based on the length of the light set. The 120w is for 2ft while the 160w is for 3ft.

Yan...try De-Lighting .....Razali is the owner and he is the distributor of Razors....9752 5051

this thread is poisonous better stay away or else more $ to be spend

@milk_vanilla....technically speaking I got poisoned by you indirectly because you gave me Razali's number....so I am just merely returning the favor....

Wait till I review the Mitras 8000K in a couple of months time....I think the ones I ordered will be in by September....

Once mitras kicked in, You should impress more people by open house bro.

I'm using the 60w 1ft version for my nano tank. It has to be placed at the highest position using the provided legs, or light spread isn't sufficient and stem plants grow towards the middle. Even at the highest position, running the lights at 70% gave me green water with ample co2 and ferts. Now running it at 50% and its all good.

@illumnae...you bought the 1ft 60 watt Razor? Its available in 8000K? Looks like you are also have the focus spot issue as well.....

30w only.....if I'm not wrong.

Yup, I have the 16000K 3ft 160W version for my marine tank and liked it alot, so I actually got the 16000K 1ft 60W version for my office marine nano. When I converted the office nano to a planted instead, I purchased the 8000K pad from Razali and he showed me how to change the pad (I still have the 16000K pad so I can switch it back when required). When he changed it for me, his spare 8000K pad had some issues, so he actually took a pad from an existing 8000K 1ft 60W version to swap into mine. At that point in time he had 2 pcs of the 8000K 1ft 60W versions in stock. And yep, the lenses don't seem to have wide enough spread, so when it's at the middle position marker, the centre is obviously brighter than the sides, which led my background stems to grow upwards towards the middle. Problem was solved when I raised the light to the maximum height position. As the light is so high up, I guess that's why 30W led over a 1ft cube is sufficient light, compared to say the UP Aqua Z series LEDs or ADA Aquasky, which use lower powered lower wattage LEDs, but place the LEDs much closer to the surface.

I am running the 160w, 10k x 2side by side on my reef tank. Maybe switching back to low maintenance biotope concept. I tried earlier adjusting the whites and a mix of blue to give a cool white colour. Hope it can pull off for the plants.

Wonderful. This means that a five feet tank can be configured.

@tropic...I could be wrong but if you use a 10K for a planted tank, you may encounter more algae issues.

Hi David, I'm glad you mentioned green water. I'm using the 160w 8000k model on my 2.5x1.5x1.5ft, planted, EI dosing, religious WC, good co2 4bps, good circulation, yet bloom, all kinds of algae festival including green water and hair algae the worse. I suspect it was the light, so I tuned in down to A:40% B:60%, 8 hours a day. Still algae persist. Do you think I am at the right % range for my tank size? This light is really difficult to catch the correct zone.

Light is hung 25cm above tank rim. My tank holds exactly 115L or 30g after minus all the scapes.

Hi Henlek

Have you settled the green water? Water change is not enough and you need use a UV sterilizer of at least 10watts and above and run your tank water till it becomes crystal clear. Do not fertilize the water while using UV. clean your filter and throw away the wool and use a new one.

I don't understand why did you turn up the percentage of the blue spectrum and cut the red spectrum. Blues somehow encourages algae growth. Keep the red and blue spectrum equal.

The 160watt Razor to be frank is a little of an overkill for your tank dimension. but since you have already bought it, lets work from here. Cut down your lights to 36% for both A and B. Observe if your plants are photosynthesizing. If no, increase both A and B by 1% till you do. If yes, you can now decide if you like to decrease both A and B by 1% to 35% (in my opinion, I would) till you reach a percentage when you don't see photosynthesis. (By this means the lowest possible plant).

As for your hair algae, you need to re-check your water circulation and the amount of CO2 present in your water column.

What kind of plants are you growing at the moment? Is this tank new or has it been running for awhile. What is the bio-load currently in the tank?

[David]

If you do cut percentage from 36%, when you reach a percentage that you don't see photosynthesis, it means your last percentage is the minimum that you need.

[tropic]

10k you may dim the blues to ensure a whiter output. 10k has more reds in the warm whites. But still I believe 8000k is still whiter than a 10k whites, if you know what I mean.
