Decided on lights. Any compatibility issues with this?

Shopping list x 3

ballast

Lumatek DIMMABLE 250W / 400W Metal Halide Electronic Ballast

bulb

RADIUM 400W 20K Single-Ended Bulb

reflector

Lumen Bright 3 SE Mogul Base PENDANT By CoralVue

***Note: The ballast is "dimmable" but I don't think the bulb is. Would this cause issues? I have a 2 year old (almost 3) I can see him turning the knobs

Is there a better ballast?

I'm going to add 4 of these over my 72Lx24Dx30T

I am not totally positive but you need a magnetic ballast, not electronic, for the radium bulbs. Also, you don't need 4 of them over that tank. 3 will be plenty with a good reflector.

Oh. I meant 3. Thank you for catching that!

I looked on marine depot :

Radium*20000K metal halide bulb offers excellent coloration and good*intensity.*It is*crisp-white with a strong*blue tint. It brings out the fluorescent pigments in*corals nicely.*Fluorescent supplementation*is usually not necessary, but can be used for added intensity and to simulate dawn and dusk. An electronic ballast, magnetic pulse-start ballast or magnetic HQI ballast is required to ignite this bulb.*This bulb is white with a blue tint on a magnetic HQI ballast. It*will burn more blue on an electronic ballast*or pulse-start ballast. An excellent choice for* reef tanks 18" or deeper.

I'm not sure how accurate this is.

It does not mention if it can run a 400w HQI

Runs 250W Metal Halide HQI or standard mogul MH; 250W HPS;
* *400W Mogul Base Metal Halide or HPS
120/240V (for 240V purchase 240V cord separately)
