I have in my possession 2 light kits. Free of charge. Enit good when you find stuff like this rare accasion but yer.

A mate moved house.

In a box there was 2 600w ballasts and 2 wing reflectors.

Can you run any smaller bulb on them or will the excess wattage will turn to heat from ballast?

Only if the ballast (digital are they?) dims down to the bulb wattage i would have thought

I don't know only at quick glimpse I saw 600w sunmaster, are 600w ballast only come in dimmable?
.

Ther sat in my van. I have look when I go up to the birds.

Just spotted part2 of your q. If you put a 400 bulb in a 600 ballast, that doest have the switch/knobs to step down voltage to 400, it will blow the bulb, or at best, burn out the bulb pretty quick. Always try and have your bulbs matching the highest wattage of your ballast.
Good bulbs can handle a bit more..thats how the superlumens work on digital ballasts, but not by 200w, only 40w or so.
Plus if the kit is in anyway dodgy/low quality then the consequences could be much worse than a blown bulb [emoji317].
Best to play it safe for the sake of a 25quid bulb.

Thats a magnetic ballast (had one myself), it needs a matching bulb

Looks like I won't be using this in my wardrobe. U less I want to keep warm with a fire.lol

Just quickly dimpled reflector or shiney Mylar type?.

As they came with dimpled wing ones

[olmec]

They work fine but there noisey, run very hot and cost a bit more lecky to run than a digital ballast

[uk Percy]

Noisy it sad in advert quiet.lol..

I won't be using them jus yet.

Perhaps in future when I get my own house where a out house can have a secret garden in it.
