LED dimmer

[Dual40IM]

I have purchased an Orphek OR LED light bar. My question is, am I able to purchase a different driver/power supply that would be dimmable/adjustable? It does not need to ramp or do anything fancy, I would just like to be able to at least control the intensity of the light output. I am afraid that it may be too powerful for my IM Lagoon 25 gal. I do have some electrical experience just not with LED drivers/power supplies. Thank in advance.

AFAICT yes.. but it's a bit hard to find. Inventronics makes more "compatible" ones but Meanwell has some close.

Need specific bar size though..

I purchased the OR 60 (24"). Do you need me to get you the specs?
Thank you for the response.

Inventronic
LUD-060S055DS2 550mA 31-156V DC OUT
Need to check.. this is a bit from memory..

Meanwell IDLC-45-500 (54-90V) w/ 500ma current as well. Slight loss of output.

This is what you need to match..more or less.

New OR 60: Input : Voltage:100V-240V AC .

Output : Voltage :40V-80V DC . Current :550mA

Power Consumption: 35W+/_5%.

Bar is 18 roughly 3.3V diodes on average most likely..

Ahh ok thanks. I was looking on Orpheks website and it says they use 3 watt LED's. So I guess 3.3 is pretty close. Thanks again.

Should, like ALL these types, be more correctly labelled "3W Class" diodes..
Wattage will depend on drive current. At 550mA's you will most likely never get "3W" each..

3W/ .550 Amps = 5.45V 750mA would probably get you 3W each.

If i use a driver that is 750mA will it damage the light do you think?

Thought I answered this.. Well it depends..
Depends on the heat sinking... I've not known any decent3W diodes that couldn't run at 750mA except for some UV/Violets and deep reds.

The heat sink is a bit small, no active cooling, and a fairly high density to believe that, at the least, one would shorten their lifespan...

You can get drivers that one can "tweak" the current.
Sadly w/ Meanwell in the past you had a choice.. Dimming or current adjustment. A few had both.
They now have an A/B series where one can do both..

Sorry no definitive answer but see little gain in going beyond spec..600 or so.. maybe.. 1A not likely..
750mA will put them at or above their 3W "class" limit.

These are not "state f the art" diodes AFAICT so pushing them could be problematic.
