May be the design, may be just that board..
Sorry if I'm being an idiot here - you mean the dimmer itself may be defective or it is poorly designed? The light itself is fine?

That is what I suspect.. Or it's the power supply"ringing"..
The light head is diodes and resistor for the most part. Nothing that would make noise.

Capacitors or chokes or any coils could which are in the power supply but you need to pin point the noise.
If in the dimmer, it's the dimmer ..which btw doesn't have coils but will have capacitors..

The noise is definitely coming from the light itself - on the side and close to where the light switch itself is. The dimmer and the power supply for the LED light are silent.

Well you got me then. The 2 were the odds on most likely spots for noise..

Not really much in the light head itself..

The light is bright and has good color, however the AC converter is making a horrible loud high pitch mosquito noise..

Just an FYI..Also note the below is mostly referrring to AC leds w/ drivers built into the bulb itself..so much doesn't apply here..

Causes and corrective actions

The main cause of noise can usually be found in the LED driver of the lamp. With LED lamps, driver electronics are integrated; for example with LED ceiling lights, the driver is usually located in the base. This electronics consists of several components. These include:

Switching power supply
Coils/chokes
LED driver
Beamsworks have no drivers.. Constant voltage using resistors to limit the current.

OPP's forgot to ask.. You don't have their timer module hooked on as well do you?

That's just weird for there to even be anything by the switch that would hum. I don't have the nicrew dimmer but I have 5 S2-Pro dimmers and 3 of the potentiometer dimmers on beamsworks and none of them produce a humming noise, any hums I have are the cheap psus. Also the s2-pro does have enough time settings for split light cycles as well as you set the ramp time (theres 8 available time settings instead of the 15min ramp up / down time) and 1 ebay listing says it works up to 36v 100W though I haven't tested that. It also has a battery/doesn't lose the time (they all had weird times on arrival and moving them between tanks they didn't lose settings)

I do not have the Beamswork timer module hooked up, only the Nicrew unit.

Its a high pitched whine, not particularly loud to be honest, but can be heard when standing in front of the thank. With it at 100%, no noise at all.

Maybe I just happen to have a strange but defective light? Does not seem like any of the usual culprits here!

Thanks for everyone's feedback thus far!

At 100% there is no "pulsing" of the voltage, just straight DC..

So the on/off current is setting up some sort of harmonic in the light head.
LED "chips" don't suffer from it.

Has to be either a capacitor on board or and ic somewhere on it .
Don't think resistors ever "sing"...

If you are handy I'd recommend a dis-assembly for a look see..
Pretty sure it comes apart quite easily..
https://www.nano-reef.com/forums/top...420-need-help/
Maybe check the board screws on the (unlikely) chance the al plate is vibrating..



You could contact "topdogsellers" on eek bay and ask if he ever heard about this..
Huge Beamswork seller there and at least in my experience, responds well to request even if not about a sale..

So this thread is awesome and unfortunately came too late since my optibright plus is passed the return window. I’ve decided to upgrade it a beamworks regardless but have a quick clarifying question.

Can someone explain the major difference between these two lights and which would be better for a low-med light plant tank? Have some amazon swords, java fern/moss and Some reopens.

Either one of them will work, but you'll want to dim the light. They're both reasonably intense lights.

I am so thankful to have found this thread! Thank you to everyone that has contributed such valuable information about Beamswork light fixtures. I have read all 24 pages here, and it was a lot to absorb, so forgive me if I am asking for redundant information...and also if I get a bit long winded here lol.

Long story short, I moved from Louisiana to Georgia and downsized to one aquarium. It was damaged by movers, but holds water so for now it's an unscaped holding area for the anubias, hornwort, duckweed, and java fern that made the move with me until the reimbursement check comes in and I can get new glass.

My tank is 25 inches tall and 36 inches long, 65 gallons. I looked at the chart that was posted, and am unsure if the "pent 0.50w timer 6500k" fixture is the same as the light that I currently have or not. It is a DA 36" 6500k .50w fixture, it does have 5 rows of white lights with a few blue ones mixed in, but it does not have a timer. It seems similar enough to me for the information in the chart to be accurate for my setup, but I wanted to ask rather than assume. My current low light plants are doing great with this light and I have no algae issues. I would like to try for a carpeted look in the new tank, maybe microsword or dwarf hairgrass, monte carlo, etc but I don't know if this light by itself can support that type of plant growth. I understand that at a certain point, CO2 injection becomes a requirement. I live in the north GA mountains, and every winter we have 2-3 power outages due to high winds and/or ice. We have a generator, but I'm still not sure if a high tech system would be the best option given the pretty much guaranteed outages that we experience. I am wondering if I buy an additional light exactly like the one I currently have, would it be possible to maintain a carpeted aquascape at 23" depth with ThriveC and ecocomplete soil or would I be sliding into CO2 territory? Has a carpeted scape ever even been successful without CO2 injection, or does it usually end up being a temporary success story for most folks that try it?
