Where to buy an FML27 Ballast? « on: April 23, 2012, 07:36:02 PM » Author: LampLover
I have one of those infamous Daylight lamps and the ballast failed, I first thought the lamp died, but I tried a new $$costly$$ lamp and it still does not light I checked the socket + cord and all is good except the ballast Is there a standard size for these or are they made specialty to fit the small arm of the fixture? The lamp says FML/27/865

There isn't a replacement, to my knowledge. You may be able to extract the ballast, find some replacement capacitors of the same (or higher voltage) ratings, and replace the capacitors to revive the existing ballast. It's usually not worth the trouble. The "ballasts" are usually just a simple unencased circuit board. You could also try removing a "ballast" from a Lights of America 27w wall or flood light, a 27w LOA CFL (if you can still find one), or even their 30w circline adapter (I have run one of my FML27's from a LOA 30w electronic ballast with no problems - and the plug fits the lamp base perfectly). A remote magnetic ballast would be a nice upgrade, but I'm not sure of the proper current for a 27w CFL - it might be about the same as a 28w PL-C. A 22w preheat circline ballast will light the lamp, but I'm sure it underdrives it.

A pair of F15T8 preheat fluorescent tube choke ballasts connected in parallel will run FML27 CFL lamps at full power.

A pair 15 watt chokes with 360 mA current is a bit high   I would recomend a pair crappy GE chokes that Home depot once sold before gone off the shelf those would of been perfect as choke  Is 320 mA and be about with in Spec of the lamp if it combined with two chokes   Or u can take a 25 watt preheat ballast but that only  430 mA

No LED gadgets, spins too slowly.  Gotta  love preheat and MV. let the lights keep my meter spinning.

You must use the FCL30 ballast made in Japan or the European standard circular tube 32W ballast .

Since a FML27 lamp runs at 55v 0.61a, a pair of dedicated F15T8 preheat fluorescent tube choke ballasts will run a FML27 at full power. Alternatively, a pair of 13w GX23 PL-S/PL-C preheat CFL choke ballasts in parallel will also run a FML27 at full power too.

In China, fml27 is often used in desk lamps. They often use warm-start electronic ballast to run, but low-power operation, the actual power is only 18watt, and the service life will be longer.
