Best light for shimmer effect

What should I look for in a light to get a natural 'shimmer' effect?

Thank you!

Shimmer is a product of point light sources and surface agitation.
Even Kessil can't make a still tank shimmer..


Cheaper Kessil substutes..
What light will depend on tank size and light needs.

Next up w/ be lights w/ 3W leds.
Then less dense sub 1w panels .

If you don't want a pendant-type of setup, the Beamswork FSPEC has quite a bit of shimmer. I'm sure that others in that category will do the same. However, you'll want to avoid LEDs that have diffusers on them, as this will greatly diminish/eliminate shimmer, e.g.; I grew tired of the shimmer effect and upgraded to a Twinstar SA (which is quite a bit better than the Beamswork). The Twinstar SA has such a filter, so no more shimmer.

Might not be at all the direction you were thinking but MQI (metal halide) bulbs have the most shimmer effect of any light I've personally owned. Bulky, produce heat, lots of potential downsides especially on a smaller tank, though.

Nothing good happens fast in an ecosystem.

For me, the shimmer that LEDs give off does not look natural at all. Looks like a disco ball to me. Metal halides are the only lights that gives a natural looking shimmer IMO.

For added shimmer that is far more flexible to match what you like personally, I suggest some very simple LED bulbs added to the normal lighting. Since there are numerous bulbs that are often used in cars, finding a 12 volt DC bulb, simple plug in bulb holders and then playing with cheap bulbs for number and location is one way to get close to what you feel is right.
A search on E-bay will turn up an amazing variety of cheap bulbs and holders for under a dollar and I pick up 12 volt power supplies at the salvage stores for around a couple dollars. add a timer to each light and you can get all kinds of effects like daylight and dark.

I run 2x20w RGB led floodlights on my 75g and with surface agitation I get a nice shimmer effect. Not quite Kessil level, but a fraction of the cost!

75g...medium tech...?
