Ballast Resistor HELP!

[brando132]

2W seems a bit low. Isn't the recommendation 4W or more?

Why is 2W not enough?

I think 75K will work wont it dave? If so here:

Meredith Instruments

They don't ship to Canada unless your order total is more than 25$, which sucks. but I think Jerry is going to send me some.

Hahaha oops! im so used to dave helping I thought he was sending them lol

Jerry is helpful too. Hi Jerry :wave:

Or you can even use 4pc 68K 2 watt resistors in Series Parallel
to get 68K 4 watt...

Wouldn't that be 8W?

Why is 2W not enough?

Let's say you try dissipating 3W with a resistor rated for 2W. What happens?
