I will try these out in my Moffatt too, Thanks.
"Hykolity Outdoor Led Flood Light, Waterproof PAR38 LED Bulb, Dimmable, 15W=150W, 5000K Daylight, 1600lm, E26 Base, UL Listed (6 Pack)"
I just got them they are too big for the Moffatt light. These are like 4.75" wide (at the lens). And the opening of the Moffatt light is about 3.5"
This is what I got as per above recomendation. Need to figure out the right size
Off the Moffatt website I think I might need to use "A16"? Whatever that designation means.
• Flexible Arm LED Task Light with C-Clamp Base attaches to any surface up to two inches thick. • Arm Length Options: 18” or 24” • Bulb: Installed, non integrated 12 watt (1100 Lumen), A19 size, LED bulb (75 watt equivalent). • Innovative aluminum heat sink maximizes LED bulb and switch life. •...

Edit: still searching and still don't quite understand the sizing. But, I think the Moffatt needs a “PAR20” or "PAR30 Short", if you want a focused beam "Flood Lamp" type bulb.
But look at the ad before you buy as some of the "PAR30 Short" are saying 3.75" wide at the lens

If anyone has used the PAR30-Short please chime in. From my searching on Amazon I see some saying that the PAR30-Short is 3.75" wide at the lens and that won't work.
From my research there are these sizes...
Bulb Shape | Bulb Size |
---|
PAR20 | 3.50" x 2.50" |
PAR30 Short | 3.50" x 3.75" |
PAR30 Long | 4.50" x 3.75" |
PAR38 | 5.00" x 4.75" |
