Hopefully this would work. I found at Homedepot last night a florescent bulb made by G.E. that says it puts out full spectrum light. It was called the ‘Sunshine’ bulb or something like that. At $4.95 for a 48" bulb this would be alot cheaper than other things I have seen. Has anybody tried these bulbs for curing UV resin? P.V.

Yeah, I almost suckered into “sunshine” bulbs until I checked out their spectral curve. They turn out a full spetrum of visible light. Cool white bulbs turn out far more UV light.

I’ve been using both types,cools,and sunshine.The sunshine bulbs work better,much better…I read the specs too.The cools should be the better bulb,so what’s up?..Herb.
Herb: I’m still following this with interest on this end. I’ve not used bulbs yet for full board exposures but have done a fair ammount of large repair areas. I’ve found that the Sylvania F40-BL (black light for insect zappers, 48" shoplight size)lamps works very well at handheld distances. The catalyst is triggered immediately and cures within 2-5 minutes. Tell us a little about how you have be using the Daylights. Full boards? or otherwise. The Mercury Vapor light project is ongoing but not finalized yet. I’ve yet to mount the thing above the work area at a distance that would allow for use over an entire board.

I’m probably wrong.>>> Don’t listen to me. I don’t have any direct experience with sunshine > spectrum. …I’ll have to see if I am totally correct.I’ll give it another comparison(maybe try some others too,like the blacklites,where did you get them Tom?)…it maybe due to something that I’m doing,right or wrong?Herb.
I always thought a “Grow Light” plant light would be swell. I thought that if you could put a grow light bulb in a flashlight…it would be a trick way to cure small ding repairs or fins…[smile]
I believe I found these at a True Value Hardware store. They stock lots of bug light bulbs, the twisty shaped ones and apparently there are some big industrial ones that use 48" standard ones too. They are really no cheaper than tanning bulbs, just more readily available.

L. I tried a herp bulb like you would use to keep your lizard warm. It was O.K. but not enough UV. It was dissappointing. I’m using the black light type flourescents used in bug zappers. The UVa and UVb wavelengths are what we’re after. There are also small UV light units used in windshield repair, dental repair and in nail salons. I just use a regular shoplight fixture and hold it over the ding work, what a time saver. Lam job and hotcoat in minutes. Tom>>> I always thought a “Grow Light” plant light would be swell.

Some 6 inch models that could be used in a handheld flourescent camplights are GE F4T5/BL and F4T5/BLB. BL lamps used in bug zappers produce long wavelength UVA radiation in the 350-400 nanometer range. Diazo Reprographic lamps emit a blue light, peaking at 417 nanometers, I’m not really sure what you need for this application, if you post it, I’ll find a good source and price for you…
