u/typeT21 ยท 1 pointr/electricians

There's a wall light here that went out recently, and I've never seen this kind before. From the label "Use only Type T21, 150 Watts Max" it looks like it's a "T21 bulb"?

I searched online for where I could get a replacement, and all the links are over $100. For example, https://www.amazon.com/SOX90-PRESSURE-SODIUM-LIGHT-HOURS/dp/B000STF83M/ is $135 + $10 shipping.

My questions (if anyone is knowledgable about this kind of bulb) are:

  1. Is this a T21 bulb?

  2. Are they really $135? Or is there a better place to get them?

  3. If I order one, can I change this light myself, or do I need a professional to do it for me? I can't quite tell if it's just a matter of taking out the glass thing, removing the burned out bulb, and putting a fresh one in, or whether there are more complicated steps involved.

  4. The light this is connected to is currently on a dimmer switch. If I look for a new T21 bulb do I need to find ones that specifically say "dimmable", or can I assume that they're all dimmable? For example, would the Amazon one ("SOX90 WATT LOW PRESSURE SODIUM BULB SUPRA LIFE T21 SHAPE BY22D BAYONET BASE SOX LAMP 90 WATTS") work? (it doesn't say "dimmable" anywhere in its description)

    Thanks for any help!
